Randomization envelopes with four different codes stratified by gender were generated using a random number generator by the study coordinator. Body composition, waist circumference, handgrip strength and physical performance were assessed at study baseline and after 5 and 10 weeks of intervention.
All subjects followed a hypocaloric diet of kcal below estimated energy needs [ 17 ]. Energy needs were estimated by multiplying measured resting energy expenditure using indirect calorimetry Vmax Encore n29; Viasys Healthcare, Houten, the Netherlands with the estimated physical activity level using a 3-day physical activity record.
Prescribed dietary protein intake was 0. For each subject the amount of energy kcal and protein g was calculated and incorporated in the dietary advice, which was given at study baseline, together with a specific food variation list for either the high protein or the normal protein diet.
Foods were not provided. During intervention, subjects of all groups received five dietary consultations; two times during a face-to-face visit at week 5 and 9, and three times by telephone in week 2, 4 and 7.
Dietary intake was assessed by a 3-day food record at baseline, after 5 and 10 weeks of intervention. Intake after 5 and 10 weeks was used to evaluate compliance to the prescribed diet. Food records were checked for completeness during study visits and additional information about unclear items or amounts was obtained.
Total energy and macronutrient intakes were calculated using a computerized Dutch Food Composition Table [ 19 ]. The exercise program involved resistance training 3 days a week for 1-h sessions.
The training started with a min warming up followed by two sets of 50 s of the following exercises: squats, lunges, chest press, shoulder press, biceps curls, triceps extensions, standing rows, step-ups and crunches.
During the week period the number of sets was gradually increased from 2 — 3 set for all exercises, the time to perform the exercises increased from 50 — 75 s, and resistance was increased by using dumbbells, elastic bands, medicine balls and a step bench.
The training ended with 5-min cooling down. The exercise program was developed by certified trainers and a physiotherapist and training sessions were supervised by certified trainers. Attendance to the training sessions was recorded by the trainer.
Body composition including FFM primary outcome and FM was determined using air displacement plethysmography BODPOD, Life Measurement Inc. BW was measured on the calibrated scale as part of the BODPOD system.
Waist circumference was measured in a standing position halfway between the anterior superior iliac spine and the lower rib after normal expiration. Handgrip strength was measured with an isometric handgrip dynamometer JAMAR J1, Sammons Preston Rolyan, Bollingbrook, CA while the subject was seated with the elbow flexed at 90°.
Three consecutive measures of handgrip strength kg at both hands were recorded to the nearest 0. Double-data entry was performed and discrepancies were checked and adjusted.
Statistical analyses were performed with FFM change as primary outcome. Subject characteristics and dietary intake at baseline were compared between groups using an independent samples t-test or the Fisher Exact test. This interaction tested whether the effect in the exercise groups is dependent on whether the subjects received the high or the normal protein diet and vice versa.
Within group changes over 10 weeks were estimated using a paired t-test. Statistical analyses were performed using SPSS software version Data in text and tables are expressed as means with SD, unless stated otherwise. We randomized subjects into the four study groups.
Before the baseline visits 22 subjects declined study participation for personal reasons. The number of subjects screened, excluded, randomized, and included in the analysis is shown in Fig. Mean age of the study population was Flow chart of number of subjects screened, randomized, completed intervention and included in the analysis.
There were no differences between groups in self-reported mean dietary intake at baseline and the energy reduction during treatment Table 2. Protein intake during the trial was 1. In the normal protein groups the protein intake during the trial was 0. The high protein groups had on average a The week weight loss trial resulted in a significantly decreased BW, waist circumference and FM in all groups.
Overall loss in BW was Figure 2 shows that the intervention did not significantly affect change in FFM, with exception of the high protein-exercise group which showed a significant increase in FFM of 0.
There was no significant effect of high protein and exercise on change in FFM and FM, but exercise significantly decreased body fat percentage with 0.
Change in body weight, fat mass and fat free mass in the four study groups. No significant change in handgrip strength was observed over time whereas all physical performance tests improved over time.
However, no significant effects of protein and exercise on handgrip strength and physical performance tests were observed Table 3. In the present randomized controlled trial in overweight and obese older adults during weight loss, we observed no significant effect of the high protein diet although at a lower level than targeted and resistance exercise on FFM preservation and no statistically significant interaction between high protein and resistance exercise.
However, only in the group with the combined intervention of high protein diet and resistance exercise program, FFM significantly increased. The recommended dietary allowance RDA for protein is 0. However, the recent expert opinion on protein requirements of older adults is higher, and recommended protein intake ranges from 1.
Specific recommendations for obese older adults during weight loss do not exist. Weijs et al. In this study we demonstrated that it is difficult to reach a 1. Although subjects in the high protein groups had a 16 g per day higher protein intake compared to the normal protein groups mean intake was 0.
Previously, we studied the effect of a high-whey protein, leucine and vitamin D supplement during weight loss on muscle mass preservation in older obese adults [ 15 ]. This difference resulted in a muscle preserving effect of 0. However, besides the difference in protein intake, also other components of the supplement, including leucine, vitamin D and other micronutrients might explain the effect on preservation of FFM in that study.
Two other possible explanations for the absence of a high-protein effect on FFM preservation in the present study should be considered. Firstly, older adults might require a minimum threshold of protein with one eating moment to raise muscle protein synthesis levels.
Previous studies showed that a minimal amount of 20 g of high quality protein per meal is needed to stimulate protein synthesis above baseline levels [ 27 ]. In our former study, the protein supplement was, ten times per week, supplied as 21 g protein at once [ 15 ].
A second explanation for the absence of a high-protein effect on FFM preservation is the protein composition of the diet. Whey protein has been shown to be very effective in stimulating postprandial muscle protein accretion in older men [ 2829 ], which has been ascribed to its fast digestion and to the high leucine content.
Since we did not focus on specific types of proteins during dietary counseling it is likely that the amount of leucine known to stimulate muscle protein synthesis at least 2 g per meal [ 12 ] for older adults was not reached for most subjects in our study.
We observed no overall exercise effect, except for relative fat mass Table 3. This is in line with expectations based on literature [ 30 ]. We observed a significant improvement in physical performance during weeks intervention in all groups.
: High protein diet and exercise| What Is the High-Protein Diet? | Before commencing the test, the researchers described the goal, associated risks, discomforts, participant obligations, benefits, questions, and permission. Water consumption was permitted. Participants then completed two attempts, noting their heaviest weight lifted and the number of repetitions. The number of repetitions required to reach fatigue did not surpass ten. The participants were given 3—5 min of rest between trials, and there was no stimulating input throughout testing. Upper- and lower-body anaerobic power was assessed via Monark Wingate cycle ergometry Monark model e, Vansbro, Sweden as previously described 35 , Briefly, participants were acquainted with the test and instructed to stay seated in the saddle for the test duration. Participants cycled or cranked against a pre-determined resistance 7. Peak power output was documented in real-time during the test using Monark Anaerobic test software 3. Liver enzymes [alanine transaminase ALT; intra-assay CV: 1. Liver and kidney function markers and lipid profiles [low-density lipoprotein LDL; intra-assay CV: 0. were measured in duplicate using Pars Azmoon kits and the spectrophotometric method DiaSys Diagnostic Systems GmbH, Germany. This phase allowed instruction relating to correct lifting technique, and familiarization with all exercises and equipment, and ensured that the participants initiated the study with a comparable training base Repetitions varied from 6 to 12 and exercises in order included leg extension, leg curl, leg press, calf raises, chest press, lat pulldown, lateral raise, biceps curl, triceps extension, abdominal crunch, and back extension. Participant supervision was performed using one personal trainer for five participants eight personal trainers in total. The periodized RT protocols were adapted from previous literature on older adults 9 , 39 — RT volume was calculated using the following formula in each session and was reported weekly 43 :. To assist in achieving their targeted protein intake i. Participants attended consultations with an accredited practicing dietitian every week, where they were provided guidelines to reach protein and energy needs. Protein quantities were consumed via foods, and habitual dietary protein intake remained stable throughout the intervention for both groups. Participants were asked to remain in a positive energy balance to alleviate any potential of energetic stress-related interferences to anabolic adaptations 44 , All dietary intake data were analyzed using Diet Analysis Plus, version 10; Cengage to ensure the same food database was used for all analyses. A priori sample size calculation was conducted using G-power 3. The normality of the distribution of all variables was evaluated before performing statistical analyzes using the Shapiro—Wilk test; there were no missing values at any time point. Baseline characteristics at PRE between groups were reported using mean SD. Effects of training and nutritional interventions on dependent variables were analyzed using analysis of covariance ANCOVA to determine the differences between the groups over time. Training volume was analyzed using repeated measures of ANOVA. Values between 0 and 0. Values between 0. All analyses were performed using SPSS 26, and figure production was performed using GraphPad Prism version 8. Sixty participants were assessed for eligibility and twenty did not meet the inclusion criteria Figure 2. Three participants from each group personal issues and COVID withdrew from the study. There were no significant between-group differences in all baseline characteristics Table 2.

Changes in body composition throughout the intervention are shown in Figure 3. Figure 3. Effects of resistance training in combination with high and low protein diet on body composition and muscular performance. Changes in muscular performance throughout the intervention are shown in Figure 3. To investigate any potential relationships between training-induced changes in SMM Δ SMM and changes in muscular performance Δ performance variable, independently of RHP or RLP group , a correlation matrix was generated Figure 4A. Lower body strength Figure 4C , upper body power Figure 4D , and lower body endurance Figure 4G showed moderate positive relationships with Δ SMM, while upper body strength Figure 4B and upper body endurance Figure 4F showed a weak positive relationship. However, lower body power Figure 4E showed a weak negative relationship. For linear regression of individual Δ performance variable as a function of Δ SMM, data were examined by the extra sum-of-squares F test to first consider if pooled data could be considered as a single model. All data except for Δ upper and lower body strength were considered a single group. All data showed a non-significant relationship with changes in SMM. Figure 4.

Effects of resistance training in combination with high and low protein diet on relative estimated training volume. Our results demonstrate greater gains in SMM and muscular strength both upper and lower body with a daily protein intake of 1. These findings are of clinical importance since such improvements in SMM and muscular strength are important to reducing the adverse effects of sarcopenia on musculoskeletal function and health. Maintenance of skeletal muscle strength is an important factor to preserve functional capacity and independent living with advancing age Nevertheless, even in very physically active older adults e. The greater increase in SMM and strength from a high-protein diet in our current work supports previous findings in older males. However, the gains in fat-free mass and absolute 1-RM strength were not statistically significant compared to the control group 1. In regards to power, no change was noted in the countermovement jump. Overall, these results suggest that the intake of a high-protein dairy milk beverage, in combination with RT, elicits greater effects on skeletal muscle strength, but not muscle hypertrophy or power outcome, than consuming the dairy milk beverage or RT in isolation When compared to the results noted in the present study, it seems that the main influencer of the lack of difference in fat-free mass between a high protein diet in combination with RT in comparison to RT in isolation and control is the dosage of protein ingestion per day, which was not statistically different. However, in the present study, the dose of protein in the high-protein diet group 1. Second, the quantity of daily protein consumed by the supplementation groups may not have been adequate to produce a meaningful difference in strength across groups. For instance, cohorts receiving additional milk servings were ingesting 1. Muscle hypertrophy and strength adaptations may necessitate a higher protein intake e. Due to the importance of dietary distribution during the day in older adults 7 , particularly as research suggests that the distribution of protein is often inadequate at breakfast, lunch, and post-exercise in older adults 56 , we instructed our participants to consume 0. This may be another important factor in increases of SMM and strength. In contrast to changes in SMM and strength, no between-group differences were observed in the magnitude of increases in muscular power both upper and lower body , which is in agreement with a recent study in which countermovement jump was measured as muscular power Also, in the present study, there was no relationship between SMM and muscular strength with power outcomes. These results indicate that the gains in muscular power are independent of protein ingestion or SMM values and may be more dependent on exercise training mode. As muscular power is the product of contraction force and movement velocity, it is conceivable, biomechanically, that fast concentric contractions would improve muscle power more than traditional RT. Since we used traditional RT in the present study, the lack of difference between groups is perhaps unsurprising. High protein diets have been linked to possible negative effects on renal function, namely glomerular filtration rate 22 — Specifically, it has been proposed that high and persistent consumption of dietary protein may eventually lead to glomerular damage, renal impairment, and kidney failure Although such associations may be more probable in those with impaired renal function such as chronic kidney disease 60 , the relationship between increased dietary protein availability and impaired kidney and liver function seems to be significantly less pronounced in individuals with healthy kidney function Considering the protein component of our high dietary protein intervention group, which was two-fold higher than the most current national recommended daily allowance for daily protein intake, we evaluated several biochemical markers of lipid, kidney, and liver function. Our results indicated within-group increases in GGT, AST, ALT, creatinine, and urea while only ALT and creatinine values were greater in RHP compared to the RLP group. Nonetheless, our data show that older adults with healthy kidney function can consume a high protein diet i. Finally, both groups similarly decreased LDL and cholesterol with no changes in HDL, indicating the role of RT independent of protein ingestion on blood lipid health. There were several limitations of our present work. Firstly, bioelectrical impedance was used to assess body composition which is not as accurate as dual-energy x-ray absorptiometry a more suitable method for body composition measurements although is still a reliable method 66 , Additionally, we lacked control over age-matched individuals that were not previously in the military. Regarding strengths of our study design, we investigated a cohort of participants that are under-represented in the skeletal muscle and nutrition research field. Moreover, we used nutrition software to track macronutrient intake which is rarely used in the literature, in older adults. In conclusion, a daily intake of 1. Such knowledge is of critical importance for older populations since gains in SMM and strength can reduce the many deleterious effects of sarcopenia, reduce the risk of falls, and improve the quality of independent living 7 , Therefore, older adults could use the intake of 1.

| A High-Protein Diet Plan to Lose Weight and Improve Health | This can be difficult, so most people prefer to loosely follow a high protein, low carb diet by replacing high carb foods with protein sources. Although people who lead sedentary lifestyles require less protein, physically active individuals, athletes, and pregnant women need significantly more than the current RDA of 0. As such, high protein diets may provide numerous benefits — as may low carb eating patterns, which are often associated with weight loss. Protein is the most filling macronutrient and helps decrease hunger and food intake, two effects that promote weight loss. In particular, foods high in protein boost levels of fullness hormones while lowering levels of hunger hormones like ghrelin 6. High protein diets also help enhance the thermic effect of food, or the calories burned during digestion. This may be due to the greater oxygen demand required to break down protein-rich foods 6. These diets also lead to higher ketone body production, particularly of beta hydroxybutyrate BHB. Your liver produces ketone bodies when glucose availability is reduced. Studies show that increased BHB levels help suppress appetite 8. On average, the men in the high protein, low carb group lost 15 pounds 6. Many other studies reveal that high protein, low carb diets are more effective for weight loss than those higher in carbs and protein 9 , 10 , 11 , Still, total calorie intake and calorie burning are the most important factors for weight loss. Yet, this loss can gradually lower your metabolism, as greater muscle mass increases the number of calories you burn while at rest High protein diets can help preserve muscle mass during weight loss and may even increase muscle mass. Increasing protein intake while cutting — calories per day has been shown to maintain muscle mass while promoting fat loss. However, this effect is lost during more severe calorie restriction, such as during poorly planned, very low calorie diets 14 , Additionally, studies show that combining a high protein diet with exercise can boost fat loss while building lean body mass. In a 4-week study, 20 men who exercised intensely 6 days per week ate either a high protein diet of 1. Those following the high protein diet lost more body fat and gained about 3 pounds 1. Other studies note that high protein diets promote increased or stable muscle mass during weight loss for both men and women, compared with lower protein diets 10 , Plus, eating a low calorie, high protein diet has been shown to help athletes gain muscle mass during training. A study in 48 athletes found that those who ate a minimum of 1. These results occurred despite the high protein group consuming more calories per day than the control group. Low carb diets have likewise been shown to help reduce fat mass while maintaining muscle mass 20 , High protein, low carb diets may promote weight loss, preserve muscle mass, improve blood sugar control, lower your risk of heart disease, and enhance bone health. Some studies associate high protein diets with an increased risk of heart disease and heart failure. However, the men with the highest protein intake were also more likely to be overweight and have diabetes, both of which are risk factors for heart failure Research has also linked high protein diets — primarily those with lots of animal protein — to an increased risk of certain cancers , including colorectal cancer, as well as negative effects on bone, liver, and kidney health 31 , It should be noted that high protein diets are widely considered safe for those with normal kidney function, though those with kidney disease should avoid this eating pattern 2. Very low carb diets are also tied to negative effects, including a potentially increased risk of death from all causes. Nonetheless, more high quality, long-term research on the downsides of both low carb and high protein diets is needed 2. For most physically active people, a daily protein intake of 0. Eating a balanced, nutrient-rich diet, staying within your calorie needs, exercising , and reducing your intake of processed foods and added sugar are much more important to your well-being than your macronutrient ratios. High protein, low carb diets are linked to a few downsides, including an increased risk of some cancers. Plus, most people have no need for all the protein that this eating pattern encourages. You should limit the following:. You can include healthy, high carb foods like starchy vegetables and fruits in moderation. Remember that your total carb intake depends on your desired macronutrient ranges. Depending on your macronutrient goals, you may also need to reduce your intake of high fat foods like fatty meats and oils. Highly refined carb foods like pasta, bread, sugar, and sweetened beverages should be restricted during a high protein, low carb diet. Eating mostly whole, nutrient-rich foods is best on a high protein, low carb diet — as with any healthy diet. Fruits, starchy vegetables, and high protein grains like quinoa can be enjoyed in moderation depending on your level of carb restriction. Fat intake also depends on your individual dietary regimen. Egg yolks, avocado, nut butters, fatty fish, and olive oil are good choices for healthy fat sources. High protein, low carb diets emphasize high protein foods like eggs, fish, tofu, and chicken, as well as low carb foods like non-starchy vegetables. The high protein, low carb diet has no one set definition but may be best for people like athletes who want to promote weight loss while preserving or increasing muscle mass. Along with HIIT, protein has really had its moment over the past couple of years. As the health and wellness movement has grown, so has the interest in the food group you learnt about in school, and lots of people have switched to high-protein diets to accompany their exercise regimens. It's easy to see why the two go hand in hand; eating a high amount of protein allows for muscles to develop, repair and maintain themselves by keeping your metabolic rate high. Which is why Dr Josh Axe DC, DNS , co-founder of Ancient Nutrition is here to lend a helping hand, flagging six of the most common mistakes people make when adapting to a high protein diet:. Dr Axe is quick to urge you to take care when selecting proteins, as some can surprisingly be harmful to your health. In fact, while salmon, chicken and grass-fed beef are all highly nutritious, processed meats like bacon, corned beef, sausage and jerky are often pumped full of additives and preservatives that can be harmful to your health," he says. Not only that, but eating processed meat has been linked to a number of different diseases, including heart disease, COPD and colorectal cancer. So what proteins should we be eating? The word protein might cause meat to spring to mind, but that's not the only option, you know. Beans, seeds, lentils and tempeh are a few of the top plant-based sources of protein, each of which offers a unique array of nutrients and health benefits," he explains. Protein might be good for you, but the same 'everything in moderation' rules apply to that, too. For example, if you eat more protein than your body needs, excess amounts will be stored as fat in the body, leading to weight gain. Eating high amounts of protein can also force your kidneys to work harder, which may worsen kidney function in those with kidney disease," the doctor adds. As a general rule of thumb, aim for 30ml of water for each pound of body weight to stay hydrated.

Additionally, many popular low carb diets, such as Atkins and ketogenic diets, are not considered high protein, low carb. This can be difficult, so most people prefer to loosely follow a high protein, low carb diet by replacing high carb foods with protein sources.
Although people who lead sedentary lifestyles require less protein, physically active individuals, athletes, and pregnant women need significantly more than the current RDA of 0. As such, high protein diets may provide numerous benefits — as may low carb eating patterns, which are often associated with weight loss.
Protein is the most filling macronutrient and helps decrease hunger and food intake, two effects that promote weight loss. In particular, foods high in protein boost levels of fullness hormones while lowering levels of hunger hormones like ghrelin 6.
High protein diets also help enhance the thermic effect of food, or the calories burned during digestion. This may be due to the greater oxygen demand required to break down protein-rich foods 6. These diets also lead to higher ketone body production, particularly of beta hydroxybutyrate BHB.
Your liver produces ketone bodies when glucose availability is reduced. Studies show that increased BHB levels help suppress appetite 8. On average, the men in the high protein, low carb group lost 15 pounds 6. Many other studies reveal that high protein, low carb diets are more effective for weight loss than those higher in carbs and protein 9 , 10 , 11 , Still, total calorie intake and calorie burning are the most important factors for weight loss.
Yet, this loss can gradually lower your metabolism, as greater muscle mass increases the number of calories you burn while at rest High protein diets can help preserve muscle mass during weight loss and may even increase muscle mass. Increasing protein intake while cutting — calories per day has been shown to maintain muscle mass while promoting fat loss.
However, this effect is lost during more severe calorie restriction, such as during poorly planned, very low calorie diets 14 , Additionally, studies show that combining a high protein diet with exercise can boost fat loss while building lean body mass. In a 4-week study, 20 men who exercised intensely 6 days per week ate either a high protein diet of 1.
Those following the high protein diet lost more body fat and gained about 3 pounds 1. Other studies note that high protein diets promote increased or stable muscle mass during weight loss for both men and women, compared with lower protein diets 10 , Plus, eating a low calorie, high protein diet has been shown to help athletes gain muscle mass during training.
A study in 48 athletes found that those who ate a minimum of 1. These results occurred despite the high protein group consuming more calories per day than the control group.
Low carb diets have likewise been shown to help reduce fat mass while maintaining muscle mass 20 , High protein, low carb diets may promote weight loss, preserve muscle mass, improve blood sugar control, lower your risk of heart disease, and enhance bone health.
Some studies associate high protein diets with an increased risk of heart disease and heart failure. However, the men with the highest protein intake were also more likely to be overweight and have diabetes, both of which are risk factors for heart failure Research has also linked high protein diets — primarily those with lots of animal protein — to an increased risk of certain cancers , including colorectal cancer, as well as negative effects on bone, liver, and kidney health 31 ,
