This is partly because of the increased losses involved in converting satiery to usable energy. The observed satiety effect Red pepper sandwich protein Protei the data from Optimisers aligns with the Protein Leverage Hypothesiswhich suggests that:.
The table Vegan multivitamin choices adapted from Cronise et al. Although carbs and protein can be converted to fat, PProtein is rPotein the dietary fat that intakw stored on your body because it is last in line to be burned.
Fat also gor less insulin to hold in storage, so it can satietj be inntake easily. The thermic effect of food is the amount of energy that is lost to heat in converting that particular intae to usable energy in your body i.
Protein has a more complex chemical structure than carbs or fat, so it takes more energy to break the carbon bonds to unlock the energy to be used in your body. Similarly, there is a range of thermic effect for carbs. Acellular carbohydrates such as sugar or refined flour may be quickly and easily converted to ATP because they are effectively predigested, while an uncooked piece of broccoli or spinach will require more effort for your body to access the energy.
Your appetite works to ensure you get a minimum amount of protein. As shown in the chart below from Lemon,endurance athletes require a minimum of around 1. You can consider this to be the minimum amount of protein required for muscle growth and recovery. Because your body is only too willing to offload metabolically expensive muscle, you should target a higher protein intake if you are trying to lose weight both in grams and percentage terms.
The chart below from a review paper by Stuart Phillips shows that the muscle preservation benefits of protein are maximised at around 2. The chart below shows that simply consuming more protein correlates with a higher overall energy intake.
The real satiety benefit comes from reducing the fat and carbs in your diet, which leads to an increase in protein percentage. The average protein intake of Optimisers is 2. The table below shows the 25th percentile protein intake along with the average and 85th percentile for each of these ways of measuring protein intake.
Optimising Nutrition adviser Dr Ted Naiman likes to talk about the protein:energy ratio. We thought it would be interesting to dig into this concept a little further, to run the satiety analysis in terms of net energy i.
after muscle protein synthesis and losses due to dietary-induced thermogenesisassuming:. the energy available after muscle protein synthesis and losses due to dietary-induced thermogenesis. The next chart shows the percentage of protein and the percentage of available energy together on the same chart.
Reducing the available energy from your food has a much stronger effect than even protein. While protein has a significant effect on our satiety, the net energy available after losses seems to have an even greater impact on the number of calories we consume.
To unpack this a little more, the table below shows the calories in each macronutrient if you burned the food in a Bomb Calorimeter i. one calorie raises the temperature of one millilitre of water by one-degree Celsius. The dietary induced thermogenesis DIT is the amount of energy that is lost in the conversion of each macronutrient contained in food to energy to be used in your body ATP or storage as fat.
As noted above, there is a range of dietary-induced thermogenesis for each macronutrient that would depend on the degree of processing i. a raw food would require more energy to process in your body to use for ATP while a cooked or highly processed food would require less.
If you want to maximise the thermic effect of food and minimise the calorie yield, you should prioritise minimally processed foods that contain less easily accessible energy from carbs and fat and more protein and fibre.
The rest of the protein you eat can be used for energy if required, but some may be excreted, and a significant amount will be used, converting that protein to usable energy in your body. Your appetite increases to make the most of any opportunity to get easy energy when it is available, especially if you are hungry and have not already filled up on nutrient-dense, high satiety foods.
Our modern food processing effectively pre-digests your food for you so you can get more energy with less effort. A recent study by Kevin Hall showed that people tend to eat significantly more calories and gain weight if the food is heavily processed even when matched for macronutrients and calories.
We gain more weight when we eat processed foods because they have lower dietary-induced thermogenesis and hence calorie for calorie more energy is available to be stored as fat. Not only do we tend to overeat foods that are heavily processed, but we are also able to obtain a lot more energy from them because of the reduced losses in converting that food into energy i.
lower thermic effect of food. So, once you have obtained your minimum protein required for muscle protein synthesis, if you want to reduce your overall energy intake without counting, weighing and measuring everything you eat, you need to focus on less efficient energy sources.
Foods and meals that contain more protein and fibre with less fat and non-fibre carbohydrates will be less efficient and provide more satiety. Your appetite for these foods will switch off earlier, while foods and meals that contain more fat and carbs are less efficient and will cause you to consume more energy.
The table below shows the macro split of the average of the data from Optimisers. Similarly, for fat and fibre. In the next example, we have the population average macronutrient split.
In this scenario, all of the protein will be used for muscle protein synthesis with none left over to be converted to energy. In this last example, we have the most nutrient-dense foodswhich not only contain a lot of nutrients, but also a significant amount of protein and fibre.
Although the dietary-induced thermogenesis for each macronutrient would likely be higher because the nutrient-dense foods are typically less processed, we have used the same DIT values. The net energy value aligns with the lowest value we see in the data from Optimisers. The chart below shows the Optimiser average and the population average along with the net energy available from the foods that have the highest nutrient density.
To make this a little more relatable, the table below shows the macronutrients and the calculated net energy for a number of popular dietary approaches. The macronutrient profile is based on our nutrient-dense food lists for various goalsso they are the best versions of each of these approaches.
The net energy for each approach is shown in the chart below. Because they all tend to move you away from processed food that tends to contain more protein and fibre, we end up with diets that yield a lot less net energy i.

Hence, in the Nutritional Optimisation Masterclasswe guide you to find your current baseline and then slowly dial in your macros to ensure you are getting the results you want in terms of blood sugar control, weight loss, fat loss and gaining lean muscle mass.
If you are looking to lose body fat, the ideal approach would be to increase your percentage protein slowly and continue to refine your diet until you get the results you want.
You can think of Dietary Induced Thermogenesis as resistance training for your metabolism. Our series of 22 nutrient-dense recipes have used this refined understanding of satiety to create the best versions of recipes tailored to suit different goals.

In phase 2, the high-protein test meal after phase 1, we found evidence of habituation to the high protein intake, but it was inconsistent. Taken together, these results tentatively support prior research that consuming a high protein intake in your regular diet can decrease the satiety you get from a high protein meal. This may be relevant for high protein cheat meals. People on very high protein diets may be more likely to overeat in a steakhouse, for example. In phase 3, the ad libitum diet phase, energy intake did not differ between groups. Since neither group ended up overeating more or less satisfied with an unrestricted energy intake, this supports the sustainability of the moderate and super high protein intakes was similar. It also supports there is no detrimental effect of going back down from a super high to a moderate protein intake. Several measures in 3 diet phases supported that a protein intake of 1. In conclusion, our results support that 1. There is no reason to restrict yourself to this if you prefer to go higher in protein, so think of it as a minimum intake. Interested in the finer details?

| Protein improves satiety: the science - Diet Doctor | However, other studies have found similar effects on satiety and food intake between whey protein and casein [ 8 , 9 ]. Eggs are a good source of proteins. Recently, eggs have been shown to enhance satiety and decrease energy intake when consumed for breakfast [ 10 ] resulting in higher weight loss during energy restriction [ 11 ]. There is limited and inconsistent evidence on the effect of egg proteins on appetite regulation. Studies have found either the same effect compared to gelatine, casein, soy, pea or wheat protein [ 12 ] or lower effect on satiety and short-term food intake compared to whey and soy protein [ 13 ]. Currently proteins of plant origin are gaining interest as an alternative to animal proteins, favoured by consumers shifting away from animal-derived proteins for health and environmental reasons. One recent study investigated pea protein and showed stronger suppression of appetite compared to whey protein when 15 g of pea protein hydrolysate was consumed in overweight subjects [ 14 ]; however, evidence remains limited. Dose plays an important role on the duration of effect of proteins on food intake. It is clear that around 50 g of protein in a food or a meal has a strong effect on satiety [ 15 ]. Nevertheless, the application of such a dose in food products remains limited. Interestingly, a recent dose-response study has shown that 20 g of whey protein is able to suppress food intake 30 min later [ 16 ]. The association of protein with satiation is not known. Only one study showed that subjects consumed less from a high protein omelette compared to a high fat omelette consumed ad libitum [ 17 ]. Satiation develops during a meal and results in the termination of a meal while satiety develops after a meal and inhibits further eating [ 17 , 18 ]. To date, most of the literature has dealt with satiety and little attention was given to satiation. In this context, we investigated the satiety benefits of 20 g of different protein sources on a meal consumed either immediately after the preload or 30 min later. Thirty-two healthy male volunteers were recruited from the local vicinity. All subjects gave their written informed consent before the start of the study. The study was an open, single-blind randomized, cross-over trial. Eligible subjects participated in a total of 7 sessions including 1 training session and 6 test sessions. Test sessions were scheduled at least 2 days apart in order to minimize taste fatigue related to the ad libitum meals. To minimize variability, subjects were asked to keep their evening meals and activity levels on the day before the test as similar as possible and to refrain from drinking alcohol on the evening before the test. Subjects were also asked not to eat or drink anything except non-carbonated water after 21h Six preloads were tested in this experiment. Pea protein, casein, whey, maltodextrin, egg albumin and a water control. The protein preloads included 20 g of egg albumin, casein protein, whey protein, pea protein and maltodextrin dissolved in non-carbonated water. The control preload was ml of non-carbonated water. All the preloads except for the water control contained around 80 kcal 20 g protein and were adjusted to a total volume of ml Table 1. The water control treatment was adjusted to ml in order to match the volume of the test preload ml plus the volume of water used to rinse their mouth 50 ml right after. The amount of protein and maltodextrin powder added to the preloads was adjusted according to the protein and maltodextrin content of the powders. Maltodextrin was included as a positive or caloric control to investigate if the protein effect on food intake and satiety is due to its caloric content. Aspartame as well as aromas and citric acid were added to improve the taste of the preloads Table 2. The amount of aspartame was adjusted to have equal sweetness in all the protein and maltodextrin preloads. The preloads were served 30 minutes before an ad libitum meal prepared at the experimental kitchen. The ad libitum meal was a "Crème Budwig", which is a typical Swiss breakfast comprised of a combination of cereals, quark, nuts and fruits. Energy and macronutrient content on g of the ad libitum breakfast was kcal, 5. Subjects were allowed to eat as much or as little as they want from the served foods but were not allowed to take food with them to consume later. The ad libitum meal was served in excess to allow subjects to eat until comfortably full. Subjects chose between 2 types of Crème Budwig apple-orange or pear-kiwi but were asked to consume the same type at each session. Meals were accompanied by non-carbonated water unlimited amount. Energy intake was measured by calculating the amount of food consumed from the ad libitum meal. All foods and water were pre-weighed by the investigators before serving and left-overs were weighed afterwards to calculate the amounts eaten. The food tray was served in the Evaluation Room and subjects were able to eat while seated in individual cubicles. VAS ratings were collected before and after the preload and at 10 min intervals between the preload and the ad libitum meal. A validated electronic system based on a Dell Pocket PC was used [ 20 ]. Subjects rated their motivation-to-eat and other sensations on a horizontal non-graded, unlabelled line anchored at each end by an opposed statement e. In the Pocket PC system, the subjects answered the questions on a 70 mm VAS by clicking on the screen with the aid of a plastic marker. The computer measures the distance in mm from the left end of the scale to the point where the subject has inserted a line. An automatic computation is made to normalize this distance to mm standard distance. All entries are automatically timed and dated. The motivation-to-eat questions were based on Hill and Blundell's motivation-to-eat questionnaire [ 21 ]. A French translation of the following questions was used:. To assess liking or palatability, the following question was asked twice, once after consuming each preload and once after consuming the ad libitum meal:. Capillary blood glucose was measured using a glucometer Accu-check Compact Plus and a lancet device Soft Clix, Roche Diagnostics. A correction factor of 1. Thus, the reported results correspond to plasma glucose concentrations. The proper use of a finger prick blood sampler lancet and glucose monitor was explained to the study participants during the training session. The measurement of the capillary glucose was supervised by the investigators. To control for CV of the glucometer, the glucose measures were performed in duplicates and the average of the 2 measures was calculated. Subjects came to the Nestlé Research Centre for 7 sessions, including one training session and 6 test sessions. During the training session, subjects' weight and height was measured and they received a letter with information about the study. They were introduced to the electronic VAS pocket PCs. Subjects tasted the beverages and foods used in the study and chose one of the two breakfasts that they preferred. They answered medical and dietary questionnaires and a French translation of the TFEQ [ 19 ]. Subjects were told that they were not allowed to drink alcohol alcohol increases passive over-consumption [ 23 ] or do vigorous exercise the day before the test day. Subjects were told that the aim of the study was to evaluate the properties of different protein beverages with no mention of food intake measurement. The test sessions timeline is shown in Figure 1. Test session timeline for Experiment 1. Subjects arrived at 8h15 in the morning and completed a baseline questionnaire to assess their state of well being and whether they were fasted on the day of the session. They then completed motivation-to-eat ratings. At 8h35 subjects consumed the preload within 5 min accompanied by 50 ml of water or just the water preload ml , and rated their satiety feelings. Between 8h40 and 9h10, subjects continued to complete satiety ratings. At 9h10, subjects measured their plasma blood glucose after they completed the satiety ratings questions. Immediately after, they consumed an ad libitum meal. Once finished 9h30 , the subjects completed 2 further sets of satiety questionnaires. They also measured their plasma glucose at different time-intervals. On the day of the test, subjects arrived at 8h15 in the morning at the Nestlé Research Center. They were invited to go into the Evaluation Room and sit in individual cubicles. Subjects were asked to refrain from talking, surfing the internet or using mobile phones, except for an emergency while they answer VAS scales or while consuming the preload or ad libitum meal. Subjects completed a baseline questionnaire to assess their state of well being and whether they were fasted on the day of the session. At 8h35 subjects consumed the preload within 5 min accompanied by 50 ml of water or just the water preload ml , and rated their satiety feelings on Pocket PCs provided by the investigators. Between 8h40 and 9h10, subjects continued to complete satiety ratings on their Pocket PCs, as prompted by an alarm. No other foods or beverages were allowed during the test session. Once finished 9h30 , the subjects completed 2 further sets of satiety questionnaires on their Pocket PC. They also measured their plasma glucose at different time-intervals 6 times till 11h Most of the subjects from experiment 1 also participated in experiment 2 except for 3 subjects. All subjects were screened for the same inclusion criteria as experiment 1. The study was an open, singly-blind, randomized, cross-over trial. Eligible subjects participated in a total of 5 sessions including 1 training session and 4 test sessions. Study design details were similar to Experiment 1. Four preloads were tested in this experiment. Whey protein, casein protein, pea protein and water control. We decided to only use protein preloads for experiment 2 as the objective is to confirm the observed effect of pea protein and casein and to compare it with another protein that did not show an effect on food intake. Whey was chosen due to its reported effect on food intake in the literature. The protein preloads included 20 g of casein protein, whey protein or pea protein dissolved in ml non-carbonated water. All the preloads except for the water control contained around 80 kcal 20 g protein Table 1. In this experiment, the protein preloads were homogenized and the pH was adjusted to improve the taste and texture. Aspartame and aromas were added as well to improve the taste. The ad libitum meal was a Bircher Muesli consisting of yoghurt and muesli. Energy and macronutrient content of g of ad libitum meal was kcal, 4. Subjects made a choice between three different yoghurts for the ad libitum breakfast. For every test session the same breakfast was served. Subjects were allowed to eat as much or as little as they want from the served foods but were not allowed to take foods with them to consume later. The ad libitum meal was served in excess to allow subjects to reach satiation. The method used to measure ratings for motivation-to-eat and palatability questions was similar to experiment 1. However, in the present experiment, the following questions were also asked between the preload and ad libitum meal to distract the subjects from thinking about the palatability of the preload while consuming the ad libitum meal:. Subjects came to the Nestlé Research Centre for 5 sessions, including a training session and 4 test sessions. The training session was described in Experiment 1, General Procedure section. On the day of the test, subjects arrived fasted from 22 h the evening before at 8. Before starting, subjects answered a questionnaire about their wellbeing and whether they were fasted on the day of the test. The order of the four preloads was randomized. Subjects were told to finish the drink within 5 minutes. They then answered a palatability question about the drink along with unrelated mood questions. Right after, the ad libitum meal was served. Subjects were allowed to eat as much as they liked. A bottle of water was offered with the breakfast. After breakfast VAS questions were answered at 0, 15, 30 and 45 minutes. Results are presented as mean ± standard error. Energy intake was analyzed using a mixed model with a random subjects effect to take into account the correlation between the repeat measurements for each subject and fixed treatment effect. Baseline covariates were adjusted for. Multiple pair-wise treatment comparisons were carried out using Tukey's Honest Significant Difference procedure. The secondary outcome measures were analyzed similarly within the mixed model analysis of covariance framework. The incremental area under the curve AUC was calculated using the trapezoide rule. Suitable normalizing transforms were applied to certain incremental AUC measures. In the case were the normalizing transformation failed, non-parametric methods were used. The within subject standard deviation is estimated to be 79 kcal from previous trials. The sample size calculation was performed based on data from our previous study published as an abstract [ 24 ]. The range for the CSS is between 0 and , 0 indicating maximum appetite sensations and minimum appetite sensations. This score is based on the concept that the 4 motivational ratings, the inverse for hunger, the inverse for desire to eat, the inverse for PFC and fullness can account for an overall measure of satiety [ 25 , 26 ]. It provides a measure of the percentage reduction in energy intake at the next meal due to the test food calories. This reduction is relative to the energy intake after the water control [ 27 ]. Thirty-two male subjects were recruited for the study. One subject dropped out and another was excluded since he did not like to have breakfast and was not feeling hungry in the morning exclusion criteria. Another subject did not complete the study since he underwent a leg surgery. Twenty-nine subjects completed the experiment with a mean age of 25 ± 4 yrs and a mean BMI of 24 ± 0. There was no significant difference among the other preloads Figure 2. Leptin and insulin are two of the hormones involved in our food intake and the sensation of satiety. They signal to the brain that there is stored energy in the form of fat tissue and energy in the form of glucose, coming from the food that recently was eaten, circulating in our body. These signals form a complex network with other satiety signals, resulting in messages telling us to reduce our food intake. Dietary proteins are important for several vital functions in our body. Such functions include production of body proteins, temperature regulation, blood sugar regulation, cellular communication and satiety. Interestingly, these processes are most distinct when the protein intake is above the dietary reference intake. Protein-rich foods include fish, chicken, beans, lentils, meat, eggs, dairy products and more. When we eat protein, its building blocks, called amino acids, need to be digested. A higher intake of protein enhances the amount of amino acids in our gut and consequently increases the digestion, or oxidation, of the amino acids. This increased oxidation boosts our sensation of feeling full. Short-term satiety is also improved with meals rich in protein. After eating a protein-rich meal, satiety is highly stimulated, compared to meals low in protein with the same amounts of calories. The explanation of this phenomenon seems to be that dietary protein generates key satiety hormones that signal to our brain that we are full. After weight loss from an energy-restricted diet, enhancing the protein intake also increases the chance of maintaining the new body weight. Weight loss induces a decrease of energy expenditure, but an enhanced protein intake spares fat-free mass, which inhibits this decrease. Remember to always try to eat well-balanced meals containing all macronutrients. Lean meats, poultry, seafood, and plant sources of protein like beans and nuts are far more healthful than fatty meats and processed meats like sausage or deli meats. Pick the healthful trio. At each meal, include foods that deliver some fat, fiber, and protein. The fiber makes you feel full right away, the protein helps you stay full for longer, and the fat works with the hormones in your body to tell you to stop eating. Adding nuts to your diet is a good way to maintain weight because it has all three. Avoid highly processed foods. The closer a food is to the way it started out, the longer it will take to digest, the gentler effect it will have on blood sugar, and the more nutrients it will contain. Choose the most healthful sources of protein. Good protein-rich foods include fish, poultry, eggs, beans, legumes, nuts, tofu, and low-fat or non-fat dairy products. These three strategies fit in with the Mediterranean and Dietary Approaches to Stop Hypertension DASH diets. The DASH diet includes 2 or fewer servings of protein per day, mostly poultry or fish.
