Nutrient timing has recently become a popular topic in the amd industry. Nutrient timing is the concept of certain macronutrients being consumed Carobhydrates certain periods throughout the day and also Fat metabolism foods your workouts.
Two questions Endurance and Stamina Building often asked about nutrient timing:. These are Carbohydrates and Nutrient Timing questions and we will dive into it a bit deeper. Below is each macronutrient Cagbohydrates broken down to better understand the science behind nutrient timing.
There is evidence Relieve post-workout soreness show similarities in the Nuttient of muscle metabolism and protein feeding. The muscle is a Cqrbohydrates tissue that constantly grows and aand throughout the day.

Sports nutrition for youth athletes, the actual muscle growth Nurient occur days Carbohydrates and Nutrient Timing Carbohgdrates not in the Carbohydrattes post training. Carbohydrate timing is more complex than protein timing. How often you eat protein is more important than timing it around workouts.
However, it is the opposite for carbohydrates. The frequency of carb intake is not really an issue until we are consuming vast amounts of carbohydrates. In that case, carbohydrate consumption can become too large to be synthesized into glycogen stores and deposited more as a fat.
Therefore, the timing of carb intake becomes more important to increase its frequency throughout several meals. Timing carb intake as it relates to physical activity has several distinct phases. The first window would be the pre-workout phase.
The pre-workout phase is important in replacing glycogen stores, which supplies blood glucose energy to the nervous system and muscles for contraction. Having full glycogen stores will allow better workout performances.
Carbohydrates also have been shown to be helpful in preventing muscle loss when ingested during the pre-workout phase. For this to be effective pre-workout carbs would need to be consumed hours before training.
The next phase is post workout carbs which have similar effects as pre-workout carbs. They have an anti-catabolism mechanism as well as glycogen repletion and will activate anabolic effects. Protein combined with carbs helps to blunt the catabolism process. These carbs help with glycogen repletion so we do not have chronically low glycogen stores effecting workout performance and muscle growth.
Consuming carbs right after training helps with the likelihood of those carbs being used as glycogen. The alternative is being converted to fat stores at rest. The anabolic affects occur by spiking insulin. Insulin stimulates muscle growth upon binding to the muscle cell surface.
Post-workout carbs show a lot of benefit for your performance and your absorption for glycogen stores. They need to be consumed in a ratio as your pre-workout carbs.
The last macro to worry about for nutrient timing is fats. Fats are very difficult to digest. They slow down the digestion of proteins and lower the glycemic index of carbs. They slow down your digestion of proteins from one to seven hours depending on how much fat is consumed with the protein.
Fats need to be consumed away from your workouts. This way they do not affect the nervous system functionality and glycogen stores of which carbs are trying to promote.
There are exceptions for endurance athletes training for several hours due to the specific energy system they are training because they will be burning more fats during that state. Now that we have talked about the different timings of the different macros, I find it important to also tell you how important nutrient timing is to weight loss.
When you total up all the variables to consider when losing weight, timing falls third in line. Caloric balance and macronutrient amounts take the top two spots.
A deviation from either one of these will make or break a diet plan. As long as you get your calories and macros right, timing is a much smaller concern. For those trying to obtain the loss of those last few pounds need to be more conscientious about their intake timing in order to make the biggest difference.
If you want the best possible results, then nutrient timing could be something to consider. And if you are considering it, follow the macros per meal breakdown Macrostax provides in the app. One you set a time of day to workout, Macrostax will assign pre and post workout meals with higher carb and lower fat amounts like we talked about to help you optimize your nutrient timing.

: Carbohydrates and Nutrient Timing| Effective Nutrient Timing for Athletes | These results were seen regardless of the extent of circulating insulin levels. Thus, it remains questionable as to what, if any, positive effects are realized with respect to muscle growth from spiking insulin after resistance training. Perhaps the most touted benefit of post-workout nutrient timing is that it potentiates increases in MPS. Resistance training alone has been shown to promote a twofold increase in protein synthesis following exercise, which is counterbalanced by the accelerated rate of proteolysis [ 36 ]. It appears that the stimulatory effects of hyperaminoacidemia on muscle protein synthesis, especially from essential amino acids, are potentiated by previous exercise [ 35 , 50 ]. There is some evidence that carbohydrate has an additive effect on enhancing post-exercise muscle protein synthesis when combined with amino acid ingestion [ 51 ], but others have failed to find such a benefit [ 52 , 53 ]. However, despite the common recommendation to consume protein as soon as possible post-exercise [ 60 , 61 ], evidence-based support for this practice is currently lacking. Levenhagen et al. Employing a within-subject design,10 volunteers 5 men, 5 women consumed an oral supplement containing 10 g protein, 8 g carbohydrate and 3 g fat either immediately following or three hours post-exercise. A limitation of the study was that training involved moderate intensity, long duration aerobic exercise. In contrast to the timing effects shown by Levenhagen et al. Notably, Fujita et al [ 64 ] saw opposite results using a similar design, except the EAA-carbohydrate was ingested 1 hour prior to exercise compared to ingestion immediately pre-exercise in Tipton et al. Adding yet more incongruity to the evidence, Tipton et al. Collectively, the available data lack any consistent indication of an ideal post-exercise timing scheme for maximizing MPS. It also should be noted that measures of MPS assessed following an acute bout of resistance exercise do not always occur in parallel with chronic upregulation of causative myogenic signals [ 66 ] and are not necessarily predictive of long-term hypertrophic responses to regimented resistance training [ 67 ]. Moreover, the post-exercise rise in MPS in untrained subjects is not recapitulated in the trained state [ 68 ], further confounding practical relevance. Thus, the utility of acute studies is limited to providing clues and generating hypotheses regarding hypertrophic adaptations; any attempt to extrapolate findings from such data to changes in lean body mass is speculative, at best. A number of studies have directly investigated the long-term hypertrophic effects of post-exercise protein consumption. The results of these trials are curiously conflicting, seemingly because of varied study design and methodology. Moreover, a majority of studies employed both pre- and post-workout supplementation, making it impossible to tease out the impact of consuming nutrients after exercise. Esmarck et al. Thirteen untrained elderly male volunteers were matched in pairs based on body composition and daily protein intake and divided into two groups: P0 or P2. Subjects performed a progressive resistance training program of multiple sets for the upper and lower body. Training was carried out 3 days a week for 12 weeks. At the end of the study period, cross-sectional area CSA of the quadriceps femoris and mean fiber area were significantly increased in the P0 group while no significant increase was seen in P2. These results support the presence of a post-exercise window and suggest that delaying post-workout nutrient intake may impede muscular gains. In contrast to these findings, Verdijk et al. Twenty-eight untrained subjects were randomly assigned to receive either a protein or placebo supplement consumed immediately before and immediately following the exercise session. Subjects performed multiple sets of leg press and knee extension 3 days per week, with the intensity of exercise progressively increased over the course of the 12 week training period. No significant differences in muscle strength or hypertrophy were noted between groups at the end of the study period indicating that post exercise nutrient timing strategies do not enhance training-related adaptation. It should be noted that, as opposed to the study by Esmark et al. In an elegant single-blinded design, Cribb and Hayes [ 70 ] found a significant benefit to post-exercise protein consumption in 23 recreational male bodybuilders. Subjects were randomly divided into either a PRE-POST group that consumed a supplement containing protein, carbohydrate and creatine immediately before and after training or a MOR-EVE group that consumed the same supplement in the morning and evening at least 5 hours outside the workout. Results showed that the PRE-POST group achieved a significantly greater increase in lean body mass and increased type II fiber area compared to MOR-EVE. Findings support the benefits of nutrient timing on training-induced muscular adaptations. The study was limited by the addition of creatine monohydrate to the supplement, which may have facilitated increased uptake following training. Moreover, the fact that the supplement was taken both pre- and post-workout confounds whether an anabolic window mediated results. Willoughby et al. Nineteen untrained male subjects were randomly assigned to either receive 20 g of protein or 20 grams dextrose administered 1 hour before and after resistance exercise. Training was performed 4 times a week over the course of 10 weeks. At the end of the study period, total body mass, fat-free mass, and thigh mass was significantly greater in the protein-supplemented group compared to the group that received dextrose. Given that the group receiving the protein supplement consumed an additional 40 grams of protein on training days, it is difficult to discern whether results were due to the increased protein intake or the timing of the supplement. In a comprehensive study of well-trained subjects, Hoffman et al. Seven participants served as unsupplemented controls. Workouts consisted of 3—4 sets of 6—10 repetitions of multiple exercises for the entire body. Training was carried out on 4 day-a-week split routine with intensity progressively increased over the course of the study period. After 10 weeks, no significant differences were noted between groups with respect to body mass and lean body mass. The study was limited by its use of DXA to assess body composition, which lacks the sensitivity to detect small changes in muscle mass compared to other imaging modalities such as MRI and CT [ 76 ]. Hulmi et al. High-intensity resistance training was carried out over 21 weeks. Supplementation was provided before and after exercise. At the end of the study period, muscle CSA was significantly greater in the protein-supplemented group compared to placebo or control. A strength of the study was its long-term training period, providing support for the beneficial effects of nutrient timing on chronic hypertrophic gains. Again, however, it is unclear whether enhanced results associated with protein supplementation were due to timing or increased protein consumption. Most recently, Erskine et al. Subjects were 33 untrained young males, pair-matched for habitual protein intake and strength response to a 3-week pre-study resistance training program. After a 6-week washout period where no training was performed, subjects were then randomly assigned to receive either a protein supplement or a placebo immediately before and after resistance exercise. Training consisted of 6— 8 sets of elbow flexion carried out 3 days a week for 12 weeks. No significant differences were found in muscle volume or anatomical cross-sectional area between groups. The hypothesis is based largely on the pre-supposition that training is carried out in a fasted state. During fasted exercise, a concomitant increase in muscle protein breakdown causes the pre-exercise net negative amino acid balance to persist in the post-exercise period despite training-induced increases in muscle protein synthesis [ 36 ]. Thus, in the case of resistance training after an overnight fast, it would make sense to provide immediate nutritional intervention--ideally in the form of a combination of protein and carbohydrate--for the purposes of promoting muscle protein synthesis and reducing proteolysis, thereby switching a net catabolic state into an anabolic one. Over a chronic period, this tactic could conceivably lead cumulatively to an increased rate of gains in muscle mass. This inevitably begs the question of how pre-exercise nutrition might influence the urgency or effectiveness of post-exercise nutrition, since not everyone engages in fasted training. Tipton et al. Although this finding was subsequently challenged by Fujita et al. These data indicate that even minimal-to-moderate pre-exercise EAA or high-quality protein taken immediately before resistance training is capable of sustaining amino acid delivery into the post-exercise period. Given this scenario, immediate post-exercise protein dosing for the aim of mitigating catabolism seems redundant. The next scheduled protein-rich meal whether it occurs immediately or 1—2 hours post-exercise is likely sufficient for maximizing recovery and anabolism. On the other hand, there are others who might train before lunch or after work, where the previous meal was finished 4—6 hours prior to commencing exercise. This lag in nutrient consumption can be considered significant enough to warrant post-exercise intervention if muscle retention or growth is the primary goal. Layman [ 77 ] estimated that the anabolic effect of a meal lasts hours based on the rate of postprandial amino acid metabolism. However, infusion-based studies in rats [ 78 , 79 ] and humans [ 80 , 81 ] indicate that the postprandial rise in MPS from ingesting amino acids or a protein-rich meal is more transient, returning to baseline within 3 hours despite sustained elevations in amino acid availability. In light of these findings, when training is initiated more than ~3—4 hours after the preceding meal, the classical recommendation to consume protein at least 25 g as soon as possible seems warranted in order to reverse the catabolic state, which in turn could expedite muscular recovery and growth. However, as illustrated previously, minor pre-exercise nutritional interventions can be undertaken if a significant delay in the post-exercise meal is anticipated. An interesting area of speculation is the generalizability of these recommendations across training statuses and age groups. Burd et al. This suggests a less global response in advanced trainees that potentially warrants closer attention to protein timing and type e. In addition to training status, age can influence training adaptations. The mechanisms underlying this phenomenon are not clear, but there is evidence that in younger adults, the acute anabolic response to protein feeding appears to plateau at a lower dose than in elderly subjects. Illustrating this point, Moore et al. In contrast, Yang et al. These findings suggest that older subjects require higher individual protein doses for the purpose of optimizing the anabolic response to training. The body of research in this area has several limitations. First, while there is an abundance of acute data, controlled, long-term trials that systematically compare the effects of various post-exercise timing schemes are lacking. The majority of chronic studies have examined pre- and post-exercise supplementation simultaneously, as opposed to comparing the two treatments against each other. This prevents the possibility of isolating the effects of either treatment. That is, we cannot know whether pre- or post-exercise supplementation was the critical contributor to the outcomes or lack thereof. Another important limitation is that the majority of chronic studies neglect to match total protein intake between the conditions compared. Further, dosing strategies employed in the preponderance of chronic nutrient timing studies have been overly conservative, providing only 10—20 g protein near the exercise bout. More research is needed using protein doses known to maximize acute anabolic response, which has been shown to be approximately 20—40 g, depending on age [ 84 , 85 ]. There is also a lack of chronic studies examining the co-ingestion of protein and carbohydrate near training. Thus far, chronic studies have yielded equivocal results. On the whole, they have not corroborated the consistency of positive outcomes seen in acute studies examining post-exercise nutrition. Another limitation is that the majority of studies on the topic have been carried out in untrained individuals. Muscular adaptations in those without resistance training experience tend to be robust, and do not necessarily reflect gains experienced in trained subjects. It therefore remains to be determined whether training status influences the hypertrophic response to post-exercise nutritional supplementation. A final limitation of the available research is that current methods used to assess muscle hypertrophy are widely disparate, and the accuracy of the measures obtained are inexact [ 68 ]. As such, it is questionable whether these tools are sensitive enough to detect small differences in muscular hypertrophy. Although minor variances in muscle mass would be of little relevance to the general population, they could be very meaningful for elite athletes and bodybuilders. Thus, despite conflicting evidence, the potential benefits of post-exercise supplementation cannot be readily dismissed for those seeking to optimize a hypertrophic response. Practical nutrient timing applications for the goal of muscle hypertrophy inevitably must be tempered with field observations and experience in order to bridge gaps in the scientific literature. With that said, high-quality protein dosed at 0. For example, someone with 70 kg of LBM would consume roughly 28—35 g protein in both the pre- and post exercise meal. Exceeding this would be have minimal detriment if any, whereas significantly under-shooting or neglecting it altogether would not maximize the anabolic response. Due to the transient anabolic impact of a protein-rich meal and its potential synergy with the trained state, pre- and post-exercise meals should not be separated by more than approximately 3—4 hours, given a typical resistance training bout lasting 45—90 minutes. If protein is delivered within particularly large mixed-meals which are inherently more anticatabolic , a case can be made for lengthening the interval to 5—6 hours. This strategy covers the hypothetical timing benefits while allowing significant flexibility in the length of the feeding windows before and after training. Specific timing within this general framework would vary depending on individual preference and tolerance, as well as exercise duration. One of many possible examples involving a minute resistance training bout could have up to minute feeding windows on both sides of the bout, given central placement between the meals. In contrast, bouts exceeding typical duration would default to shorter feeding windows if the 3—4 hour pre- to post-exercise meal interval is maintained. Even more so than with protein, carbohydrate dosage and timing relative to resistance training is a gray area lacking cohesive data to form concrete recommendations. It is tempting to recommend pre- and post-exercise carbohydrate doses that at least match or exceed the amounts of protein consumed in these meals. However, carbohydrate availability during and after exercise is of greater concern for endurance as opposed to strength or hypertrophy goals. Furthermore, the importance of co-ingesting post-exercise protein and carbohydrate has recently been challenged by studies examining the early recovery period, particularly when sufficient protein is provided. Koopman et al [ 52 ] found that after full-body resistance training, adding carbohydrate 0. Subsequently, Staples et al [ 53 ] reported that after lower-body resistance exercise leg extensions , the increase in post-exercise muscle protein balance from ingesting 25 g whey isolate was not improved by an additional 50 g maltodextrin during a 3-hour recovery period. For the goal of maximizing rates of muscle gain, these findings support the broader objective of meeting total daily carbohydrate need instead of specifically timing its constituent doses. Collectively, these data indicate an increased potential for dietary flexibility while maintaining the pursuit of optimal timing.

During exercise, frequent feedings of g of high GI carbs per hour of training can help increase performance, maintain normal blood glucose levels, and prevent early fatigue. Post-exercise, protein should be consumed as soon as possible after exercise. However, you can still maximally stimulate muscle protein synthesis up to 2 hours post-exercise by consuming g of a rich protein. When it comes to strength, recovery, and improved body composition it is recommended that protein be consumed in intervals of every hours to promote a positive state of nitrogen balance. If your goal is to build muscle, carbohydrates, and protein should be consumed together. Nutrient timing can be employed at any level, however, if you are looking to gain a competitive edge and boost your performance, nutrient timing may be the key to your success.

| Does Fast-and-Burn Work for Weight Loss? | The alternative is being converted to fat stores at rest. The anabolic affects occur by spiking insulin. Insulin stimulates muscle growth upon binding to the muscle cell surface. Post-workout carbs show a lot of benefit for your performance and your absorption for glycogen stores. They need to be consumed in a ratio as your pre-workout carbs. The last macro to worry about for nutrient timing is fats. Fats are very difficult to digest. They slow down the digestion of proteins and lower the glycemic index of carbs. They slow down your digestion of proteins from one to seven hours depending on how much fat is consumed with the protein. Fats need to be consumed away from your workouts. This way they do not affect the nervous system functionality and glycogen stores of which carbs are trying to promote. There are exceptions for endurance athletes training for several hours due to the specific energy system they are training because they will be burning more fats during that state. Now that we have talked about the different timings of the different macros, I find it important to also tell you how important nutrient timing is to weight loss. When you total up all the variables to consider when losing weight, timing falls third in line. Caloric balance and macronutrient amounts take the top two spots. A deviation from either one of these will make or break a diet plan. As long as you get your calories and macros right, timing is a much smaller concern. For those trying to obtain the loss of those last few pounds need to be more conscientious about their intake timing in order to make the biggest difference. If you want the best possible results, then nutrient timing could be something to consider. And if you are considering it, follow the macros per meal breakdown Macrostax provides in the app. One you set a time of day to workout, Macrostax will assign pre and post workout meals with higher carb and lower fat amounts like we talked about to help you optimize your nutrient timing.

Again, however, it is unclear whether enhanced results associated with protein supplementation were due to timing or increased protein consumption. Most recently, Erskine et al. Subjects were 33 untrained young males, pair-matched for habitual protein intake and strength response to a 3-week pre-study resistance training program. After a 6-week washout period where no training was performed, subjects were then randomly assigned to receive either a protein supplement or a placebo immediately before and after resistance exercise. Training consisted of 6— 8 sets of elbow flexion carried out 3 days a week for 12 weeks. No significant differences were found in muscle volume or anatomical cross-sectional area between groups. The hypothesis is based largely on the pre-supposition that training is carried out in a fasted state. During fasted exercise, a concomitant increase in muscle protein breakdown causes the pre-exercise net negative amino acid balance to persist in the post-exercise period despite training-induced increases in muscle protein synthesis [ 36 ]. Thus, in the case of resistance training after an overnight fast, it would make sense to provide immediate nutritional intervention--ideally in the form of a combination of protein and carbohydrate--for the purposes of promoting muscle protein synthesis and reducing proteolysis, thereby switching a net catabolic state into an anabolic one. Over a chronic period, this tactic could conceivably lead cumulatively to an increased rate of gains in muscle mass. This inevitably begs the question of how pre-exercise nutrition might influence the urgency or effectiveness of post-exercise nutrition, since not everyone engages in fasted training. Tipton et al. Although this finding was subsequently challenged by Fujita et al. These data indicate that even minimal-to-moderate pre-exercise EAA or high-quality protein taken immediately before resistance training is capable of sustaining amino acid delivery into the post-exercise period. Given this scenario, immediate post-exercise protein dosing for the aim of mitigating catabolism seems redundant. The next scheduled protein-rich meal whether it occurs immediately or 1—2 hours post-exercise is likely sufficient for maximizing recovery and anabolism. On the other hand, there are others who might train before lunch or after work, where the previous meal was finished 4—6 hours prior to commencing exercise. This lag in nutrient consumption can be considered significant enough to warrant post-exercise intervention if muscle retention or growth is the primary goal. Layman [ 77 ] estimated that the anabolic effect of a meal lasts hours based on the rate of postprandial amino acid metabolism. However, infusion-based studies in rats [ 78 , 79 ] and humans [ 80 , 81 ] indicate that the postprandial rise in MPS from ingesting amino acids or a protein-rich meal is more transient, returning to baseline within 3 hours despite sustained elevations in amino acid availability. In light of these findings, when training is initiated more than ~3—4 hours after the preceding meal, the classical recommendation to consume protein at least 25 g as soon as possible seems warranted in order to reverse the catabolic state, which in turn could expedite muscular recovery and growth. However, as illustrated previously, minor pre-exercise nutritional interventions can be undertaken if a significant delay in the post-exercise meal is anticipated. An interesting area of speculation is the generalizability of these recommendations across training statuses and age groups. Burd et al. This suggests a less global response in advanced trainees that potentially warrants closer attention to protein timing and type e. In addition to training status, age can influence training adaptations. The mechanisms underlying this phenomenon are not clear, but there is evidence that in younger adults, the acute anabolic response to protein feeding appears to plateau at a lower dose than in elderly subjects. Illustrating this point, Moore et al. In contrast, Yang et al. These findings suggest that older subjects require higher individual protein doses for the purpose of optimizing the anabolic response to training. The body of research in this area has several limitations. First, while there is an abundance of acute data, controlled, long-term trials that systematically compare the effects of various post-exercise timing schemes are lacking. The majority of chronic studies have examined pre- and post-exercise supplementation simultaneously, as opposed to comparing the two treatments against each other. This prevents the possibility of isolating the effects of either treatment. That is, we cannot know whether pre- or post-exercise supplementation was the critical contributor to the outcomes or lack thereof. Another important limitation is that the majority of chronic studies neglect to match total protein intake between the conditions compared. Further, dosing strategies employed in the preponderance of chronic nutrient timing studies have been overly conservative, providing only 10—20 g protein near the exercise bout. More research is needed using protein doses known to maximize acute anabolic response, which has been shown to be approximately 20—40 g, depending on age [ 84 , 85 ]. There is also a lack of chronic studies examining the co-ingestion of protein and carbohydrate near training. Thus far, chronic studies have yielded equivocal results. On the whole, they have not corroborated the consistency of positive outcomes seen in acute studies examining post-exercise nutrition. Another limitation is that the majority of studies on the topic have been carried out in untrained individuals. Muscular adaptations in those without resistance training experience tend to be robust, and do not necessarily reflect gains experienced in trained subjects. It therefore remains to be determined whether training status influences the hypertrophic response to post-exercise nutritional supplementation. A final limitation of the available research is that current methods used to assess muscle hypertrophy are widely disparate, and the accuracy of the measures obtained are inexact [ 68 ]. As such, it is questionable whether these tools are sensitive enough to detect small differences in muscular hypertrophy. Although minor variances in muscle mass would be of little relevance to the general population, they could be very meaningful for elite athletes and bodybuilders. Thus, despite conflicting evidence, the potential benefits of post-exercise supplementation cannot be readily dismissed for those seeking to optimize a hypertrophic response. Practical nutrient timing applications for the goal of muscle hypertrophy inevitably must be tempered with field observations and experience in order to bridge gaps in the scientific literature. With that said, high-quality protein dosed at 0. For example, someone with 70 kg of LBM would consume roughly 28—35 g protein in both the pre- and post exercise meal. Exceeding this would be have minimal detriment if any, whereas significantly under-shooting or neglecting it altogether would not maximize the anabolic response. Due to the transient anabolic impact of a protein-rich meal and its potential synergy with the trained state, pre- and post-exercise meals should not be separated by more than approximately 3—4 hours, given a typical resistance training bout lasting 45—90 minutes. If protein is delivered within particularly large mixed-meals which are inherently more anticatabolic , a case can be made for lengthening the interval to 5—6 hours. This strategy covers the hypothetical timing benefits while allowing significant flexibility in the length of the feeding windows before and after training. Specific timing within this general framework would vary depending on individual preference and tolerance, as well as exercise duration. One of many possible examples involving a minute resistance training bout could have up to minute feeding windows on both sides of the bout, given central placement between the meals. In contrast, bouts exceeding typical duration would default to shorter feeding windows if the 3—4 hour pre- to post-exercise meal interval is maintained. Even more so than with protein, carbohydrate dosage and timing relative to resistance training is a gray area lacking cohesive data to form concrete recommendations. It is tempting to recommend pre- and post-exercise carbohydrate doses that at least match or exceed the amounts of protein consumed in these meals. However, carbohydrate availability during and after exercise is of greater concern for endurance as opposed to strength or hypertrophy goals. Furthermore, the importance of co-ingesting post-exercise protein and carbohydrate has recently been challenged by studies examining the early recovery period, particularly when sufficient protein is provided. Koopman et al [ 52 ] found that after full-body resistance training, adding carbohydrate 0. Subsequently, Staples et al [ 53 ] reported that after lower-body resistance exercise leg extensions , the increase in post-exercise muscle protein balance from ingesting 25 g whey isolate was not improved by an additional 50 g maltodextrin during a 3-hour recovery period. For the goal of maximizing rates of muscle gain, these findings support the broader objective of meeting total daily carbohydrate need instead of specifically timing its constituent doses. Collectively, these data indicate an increased potential for dietary flexibility while maintaining the pursuit of optimal timing.

Everyday foods from home, dining facilities on base, grocery stores, and convenience stores can meet the nutritional needs of most Service Members. Carbohydrates are the best fuel for exercise—for both mind and body. Warfighters should aim to get enough carbs:. The tables below show general recommendations for each phase of nutrient timing that can be customized. Warfighters should choose what to eat based on activity type, intensity, and environmental conditions, as well as their personal preference and experience. Getting enough fluids and balancing electrolytes are also essential for peak performance. Military guidelines recommend 3—4. Drinking water with meals and snacks, and paying attention to fluid intake during and after exercise can help maintain hydration. To monitor fluid loss, Service Members can weigh themselves before and after exercise—and rehydrate accordingly. Another way to monitor hydration is by checking urine color. Generally, the lighter the urine color, the better. Service Members should aim to tailor their hydration to sweat rate, type and length of activity, environment heat, humidity, cold, altitude , equipment and clothing, and opportunity and availability to drink. For optimal fluid balance, Warfighters likely need to increase intake with heat or humidity, heavy clothes or equipment, increased intensity, or exerising longer than an hour. By the time someone feels thirsty, they might already be dehydrated, so encourage a drinking schedule. Rehydration is an important focus of the recovery phase, so encourage drinking immediately after a training, mission, or event. Electrolytes nutrients such as sodium, potassium, calcium, and magnesium are important for muscle function. Loss of electrolytes through urine and sweat can make dehydration worse than just fluid loss alone. Individual sweat rates for men and women can vary between 0. Electrolyte loss can be significant depending on training status, sweat rate, how much you eat, genetics, and prior heat exposure. For optimal performance and recovery, a Service Member should consume foods and fluids that contain electrolytes before, during, and after exercise. Service Members can get enough sodium by eating salty snacks or meals, adding salt to foods, and drinking beverages that contain sodium. Replenishing electrolytes is crucial for complete hydration. In general, consuming up to mg of caffeine amount in oz coffee approximately 30—60 minutes before an endurance event can improve performance. When using caffeine to boost performance, use it strategically, according to individual caffeine tolerance. Caffeine content varies, and not all product labels include caffeine content. For extended or sustained operations, re-dose every 3—4 hours as needed. Caffeine intake should not exceed mg in 24 hours or mg for sustained operations. High-intensity workouts lasting about an hour require only a small amount of additional fuel and fluid for peak performance. Fuel : A carb-rich meal or snack of about — calories. Tip: Avoid foods high in fat full-fat dairy or fiber raw veggies to prevent stomach upset. |

What I eat in a day / Under 20 total carbsCarbohydrates and Nutrient Timing -
So only implement these strategies if they help improve your adherence, not hinder it due to the added complication. Calorie cycling is the name given when different days of the week have different calorie targets. If you find yourself keeping to your diet during the week but struggling at the weekends, consider building more flexibility into your plan to allow that.
So for example, to maintain the daily average calorie intake, you could eat calories fewer on the weekdays so that you can eat calories extra on the weekends:. I recommend avoiding fluctuations much greater than this as it will make adherence harder and likely compromise results.
Cheat days are the name given to days where people eat whatever they want. They have no place in a diet and I strongly suggest you avoid them.
The most common pattern of people screwing up their diets or getting fat when they bulk is staying tight during the weekdays and blowing it all on the weekend.
It is perfectly possible to do this over one day as well. This means that over the weekdays you will have built up a kcal deficit.
But if you eat or drink kcal extra over the weekend, you are back where you started. Macro cycling is the name given when different days of the week have different macros targets. I recommend you avoid extreme splits in macro intake as that could also compromise recovery and hamper adherence.
As carbs balance the calorie budget, this means the training days have more carbs than the rest days. See examples at the end of this section.
Refeeds are the name given to days where more calories and carbs are eaten. The idea is to replenish muscle glycogen and help boost performance during cutting phases. Some people do this every training day like with Leangains , but when most people talk of refeeds they are referring to a once per week, carb-heavy day, which is often above caloric maintenance.
Often fat intake will be limited on these days in a bid to minimize storage, though whether this has any effect is unclear. Note : I will purposefully spare you the math in this section. But if you wish to see the formulas used, hover or click for the calorie cycling math 1 and the macro cycling math 2.
Note how personal preference is the reason behind the choice for all of these examples. He decides that he wishes to sacrifice some flexibility on the weekdays so that he has a calorie buffer on the weekend.
He chooses to split the kcal additional budget between fats and carbs evenly, so he adds 20 g of fat and 55 g of carbs to these days. Thelma wants to make her life easier, not more difficult by adding a layer of complication, so she decides against calorie or macro cycling.
As she prefers a little more fat in her diet, she chooses to swap 20 g of carbs for an additional 10 g of fat.
She wants to do both calorie and macro cycling, as she feels it will add variety in her diet each day which will make things easier to adhere to. Got a question? Ask me below. Please keep questions on topic, write clearly, concisely, and don't post diet calculations.

In this chapter the key principles you will learn about nutrient timing are: Doing nothing stupid or extreme that could compromise the rest of your efforts, Optimizing things in a way that helps you adhere, Avoiding complicated strategies unless you need them for your sport.
When Should We Eat? Suggestions For When To Eat, Relative To When You Train Should You Try Intermittent Fasting? Refeeds, Calorie Cycling, Macro Cycling, and Cheat Days Example Calorie, Macro Cycling, and Refeed Calculations For Our Four Amigos As with this series as a whole, this article is written in the order of importance that each addition will likely benefit you.
Meal Timing: How Many Meals Should We Eat? The sweet spot for meal frequency is 2—3 meals when cutting and 3—4 meals when recomping or bulking. Why I Recommend You Avoid Extreme Meal Frequencies Eating one meal a day may be the simplest choice, but it is not going to be optimal for lean mass retention when dieting, nor muscle growth when bulking.
Meal Frequency Recommendations For Those Cutting and Bulking For those cutting, it can be beneficial to have fewer meals because you can eat more at each meal.
those who ate three or four. Meal Timing: When Should We Eat? Avoid fat as this could cause stomach upset. Personally, I feel completely fine without this, but I want to state it here as an option.
Spread Your Meals evenly Across the day If you eat twice per day, make that lunch and dinner, and roughly hours apart. Spread your macros evenly As long as meals are evenly spaced, there is likely very little benefit to worrying about more specific protein or carbohydrate timing.
Avoid skewing your fat, protein, or carb intake across the course of a day too heavily. You may still find some people saying that eating fats and avoiding carbs at the start of the day and vice versa at the end of the day is beneficial. Nutrient Timing: When To Eat, Relative To When You Train Here are some detailed meal timing examples of when to eat, relative to when you train.
Early Morning fasted training This setup is the most popular with clients. IF SKIPPING BREAKFAST IF EATING BREAKFAST 25 g Whey Light Breakfast Training Training Lunch Lunch Dinner Dinner Lunchtime Training This is popular with folks who can take a slightly longer lunch than the typical hour and have a gym close to their office or in the same building.
IF SKIPPING BREAKFAST IF EATING BREAKFAST 25 g Whey Breakfast Training Training Lunch Lunch Dinner Dinner Early-Afternoon Training Fewer clients do this, but it works equally well. IF SKIPPING BREAKFAST IF EATING BREAKFAST — Breakfast Lunch Lunch ~ Training ~ Training Dinner Dinner Late-Evening Training This type of setup is best avoided if it impacts the duration or quality of sleep.
The idea that eating before bed makes you fat is a myth. Should You Try Intermittent Fasting? As consistent meal times can help with hunger regulation, I do not recommend I. The majority of those clients you see on the results page have done this. Leangains-Style Intermittent Fasting Leangains is a style of intermittent fasting developed by Swedish nutritionist Martin Berkhan.
Leangains combines breakfast skipping with calorie and macro cycling. So where does the 8-hour window come from and why is this not 7 or 9 hours? Why did Martin choose to fluctuate calorie, carb, and fat intake? Does this make a difference? Leangains Benefits Meal prep is less time-consuming.
Fewer meals mean larger meals for the same calorie budget, which is more psychologically satisfying. There is a lack of hunger in the mornings after an initial adjustment phase, which is usually 5—7 days.
People also report an increased focus in the mornings. I am one of these people and this is when I like to get my hardest cognitive tasks for the day done. Leangains Drawbacks There is a higher risk of muscle loss when dieting. The scientific literature suggests that it is likely better to space meals out further.
Some examples of clients I have worked with who skipped breakfast. None of them did any cardio. Refeeds, Calorie Cycling, Macro Cycling, and Cheat Days Calorie and macronutrient intake do not have to be the same each day of the week. Calorie cycling And How To Implement It Calorie cycling is the name given when different days of the week have different calorie targets.
Most people intend their diets to look like this: An isocaloric diet. I call this unintentional calorie cycling. Four-day training week. Calorie Cycling Gone Wrong Cheat days are the name given to days where people eat whatever they want.
Macro Cycling and How To Implement It Macro cycling is the name given when different days of the week have different macros targets. People do this with a goal to improve body composition, training effect, or performance. What Are Refeeds? Example Calorie, Macro Cycling, and Refeed Calculations Note : I will purposefully spare you the math in this section.
As Freddie has had trouble on the weekends in the past, he chooses to be stricter on the weekdays to allow more calories on the weekends. Sam never smiles. Serious Shredded Sam. Thelma chooses to swap 20 g of carbs so she can have an additional 10 g of fat each day.
Natalie chooses to go the Leangains route. Nutrient timing is about doing nothing stupid, first and foremost. Eat 2—3 meals when cutting, 3—4 meals when bulking. Spread your meals evenly across the day.
Spread your macros evenly across the day. Feel free to use calorie cycling, macro cycling, and refeeds if you feel doing so will help you adhere. Moderate to high-intensity exercise relies heavily on carbohydrates as a fuel source, however, glycogen stores in the body are limited and can only supply the body with energy for up to a few hours during continued high-intensity bouts.
Therefore, "filling up the gas tank" is imperative to improve performance and prevent fatigue. It takes roughly about hours for carbohydrates to be fully digested and assimilated into muscle and liver glycogen.
Therefore, the first feeding priority before exercise is a meal at least 4 hours before competition to fully saturate muscle glycogen stores. Want to see how you can put this information to use as a fitness pro? Look into our Certified Sports Nutrition Coach course! The purpose of post-workout feedings at specific times is to augment the recovery process, which in turn implies muscle recovery.
Muscle recovery goals will vary based on the sport an athlete is participating in but can include muscle strength, muscle growth, or prevention of muscle soreness.
Since muscles store carbohydrates and amino acids make up the structure of skeletal tissues, feedings are largely focused on carbohydrates and proteins.
When studies compared the effects of carbohydrate or protein feedings on muscle protein synthesis, they found that together they have the greatest effect on increasing muscle protein synthesis.
Regarding muscle strength and growth, it has been found that the greatest effect of protein consumption is largely dependent on the last dose consumed. Regular protein feedings every hours in doses of grams have shown the greatest benefit in improving muscle growth, and strength and leading to favorable changes in body composition.
However, regarding specific feeding windows, muscle protein synthesis is greatest immediately after up to 2 hours post-exercise. How much protein should be consumed in that time frame?
Can essential amino acids also do the trick? Doses of g of essential amino acids can also maximally stimulate muscle protein synthesis. This can improve recovery and leads to favorable changes in body composition such as increases or maintenance in lean mass and decreases in fat mass.
During exercise, frequent feedings of g of high GI carbs per hour of training can help increase performance, maintain normal blood glucose levels, and prevent early fatigue.
Post-exercise, protein should be consumed as soon as possible after exercise. However, you can still maximally stimulate muscle protein synthesis up to 2 hours post-exercise by consuming g of a rich protein. When it comes to strength, recovery, and improved body composition it is recommended that protein be consumed in intervals of every hours to promote a positive state of nitrogen balance.
If your goal is to build muscle, carbohydrates, and protein should be consumed together. Nutrient timing can be employed at any level, however, if you are looking to gain a competitive edge and boost your performance, nutrient timing may be the key to your success.
