As a trainer, clients will often msucle to you when they have questions about Nuteient diet. They may want fod know what to eat for maximum muscle gain, for instance.
Or they might wonder if certain diet Nutrient timing for muscle growth timig help speed up their fat Nutriwnt. But one topic that can typically be timlng is nutrient timing.
Nutrient timing involves eating at specific times to Nutriejt Nutrient timing for muscle growth desired growtb. The goal groqth dictate the timing Nutrienh.
Nutrient timing to increase muscle mass looks different than if the goal is weight loss, for groth. Generally, the timing of nutrition is centered around the training session.

It also helps keep blood sugar from crashing. Boost metabolism naturally reduces fatigue. Add Nutrient timing for muscle growth timinng the mix and muscle can exert more effort. It also stunts the rise of cortisol, growty in muscle recovery.
Anabolic phase : Muscpe 45 minutes after a workout is the anabolic phase. This is when damaged muscle protein starts to Vitamin D and bone health. Muscle glycogen stores are starting to restore. Pumpkin Seed Recipes for Weight Loss this phase, Concentration and brain training sensitivity initially increases, Nutrient timing for muscle growth drops rapidly.
Several hours after exercise, Nutrient timing for muscle growth musclee can occur. This can slow muscle recovery and repair. Growth phase : The growth phase starts after the anabolic stage ends and continues ffor a Nutridnt workout begins. Muscle hypertrophy occurs during this phase.
Muscle glycogen is also fully replenished. While timing nutrition may fof like a Nutrition and macronutrients of work, Nutrjent does get easier with practice.
Muslce, there are quite a few benefits in Nutrient timing for muscle growth your meal or snack. Nutrient timing can Nutrient timing for muscle growth maximize muscle growth.
A musc,e reported that consuming whey protein after lower-body resistance training contributed to greater rectus femoris muscle size. Timing your nutrition can also aid in fat loss. One study found that consuming a 1;1. Another study reports that nutrient timing also affects metabolism. If the goal is improved performance, nutrition timing can help with this too.
Research supports pre-exercise carbohydrate consumption for endurance athletes. It may be even more critical when resistance training according to an article in the Journal of Athletic Performance and Nutrition. This article explains that it works by reducing protein degradation and increasing protein synthesis.
Some research even suggests that the timing of other substances may offer more benefits. A study looked at the timing of ergogenic aids and micronutrients. It noted that timing caffeine, nitrates, and creatine affect exercise performance.
This timing also impacts the ability to gain strength and for the body to adapt to exercise. The strategy you use when timing nutrition will vary based on your desired goal. Protein is key to helping muscle grow. It is also critical for boosting muscle strength.
Consuming protein during the anabolic phase can help muscle repair after resistance exercise. It can even help reduce muscle protein breakdown the next morning according to one study.
Consuming 20 grams of protein after exercise helps support muscle protein synthesis. While it may be tempting to aim for more, one study found that this provides no additional benefit.
Protein needs vary based on level of physical activity. An athlete engaged in moderate-intensity exercise needs 0. An athlete engaging in more intense exercise needs more, or between 1.
Those engaging in resistance exercise also need this higher amount. What does nutrient timing look like if the goal is weight loss? Much of the research in this area involves eating habits, in general, as opposed to eating before, during, or after exercise.
One study that addresses this topic focuses on endurance athletes. It notes that fat loss can be achieved for this type of athlete by:. The path to fat loss without losing muscle changes depends on exercise intensity. If the intensity is high, increased carbohydrate consumption can help meet this demand.
If the workout is low intensity, focus more on protein. Performance nutrition is gaining in popularity. Some suggest that access to a sports dietitian can improve performance for pro athletes.
This is the basis of an April article published in the Journal of the International Society of Sports Nutrition. The strategy for nutrition timing varies based on the sport. If the athlete runs marathons, fueling up a few hours before the run provides energy for the event.
Carbohydrate foods are best. A good calorie count is calories or less. After the race, refuel with a light meal. If the sport relies on muscle strength, refuel with protein within a few hours. This helps the body as it repairs muscle damage. Approximately 20 grams is a good place to start.
More may be needed if the sport is intense. A carbohydrate rich meal a few hours before aerobic exercise helps provide the energy needed.
Adding a little protein can help keep the energy going. Have a banana carbohydrate with some peanut butter protein. Or eat a couple of wheat crackers carbohydrate with cubes of cheese protein. When lifting weights, post exercise protein is important.
This will help the muscle tissue recover. It also aids in skeletal muscle growth. Aim to consume this protein within a few hours. A protein shake is an easy option. Scrambling some eggs or having a salad with chicken are more options. An endurance athlete needs enough energy to sustain movement long-term.
This involves fueling the body with a high carbohydrate meal a few hours before the training. If the training session is long, a carbohydrate snack may be needed during the workout.
Afterward, have a light meal that includes both protein and carbs. Sports nutrition is an ever-changing field. And every person is different. What works for one client or athlete may not work for another. Some may benefit from carbohydrate ingestion before exercise while others gain the most advantage by exercising in a fasted state.
Working with a sports nutrition specialist can provide clients individualized guidance. It takes into account their training program. It also considers how their body responds to protein and carbs.
At the same time, this professional can help with more than just nutrient timing. They can offer advice on calorie intake, how to create a balanced meal, and more.
: Nutrient timing for muscle growth| What science says about weight lifting and meal timing | 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.

Review Open access Published: 29 January Nutrient timing revisited: is there a post-exercise anabolic window? Abstract Nutrient timing is a popular nutritional strategy that involves the consumption of combinations of nutrients--primarily protein and carbohydrate--in and around an exercise session. Introduction Over the past two decades, nutrient timing has been the subject of numerous research studies and reviews. Glycogen repletion A primary goal of traditional post-workout nutrient timing recommendations is to replenish glycogen stores. Protein breakdown Another purported benefit of post-workout nutrient timing is an attenuation of muscle protein breakdown. Protein synthesis Perhaps the most touted benefit of post-workout nutrient timing is that it potentiates increases in MPS. Muscle hypertrophy A number of studies have directly investigated the long-term hypertrophic effects of post-exercise protein consumption.

According to authors Ivy and Portman, the goals of this phase are to maintain insulin sensitivity in order to continue to replenish glycogen stores and to maintain the anabolic state.

Nutrient Timing Supplement Guidelines: Putting it Together for Yourself and Your Clients Aquatic instructors expend a lot of energy in teaching and motivating students during multi-level fitness classes. Clearly, nutrient timing may be a direction the aquatic profession may choose to pursue to determine if it provides more energy and faster recovery from a challenging teaching load. As well, some students and clients may seek similar results. From the existing research, here are some recommended guidelines of nutrient timing. Energy Phase During the energy phase a drink consisting of high-glycemic carbohydrate and protein should be consumed. This drink should contain a ratio of carbohydrate to protein and should include approximately 6 grams of protein and 24 grams of carbohydrate. Additional drink composition substances should include leucine for protein synthesis , Vitamin C and E because they reduce free-radical levels-which are a contributing cause to muscle damage , and sodium, potassium and magnesium which are important electrolytes lost in sweat. Anabolic Phase During the anabolic phase a supplement made up of high-glycemic carbohydrate and protein should be consumed. This should be a ratio of carbohydrate to protein and should contain approximately 15 g of protein and 45 grams of carbohydrate. Other important drink substances include leucine for protein synthesis , glutamine for immune system function , and antioxidant Vitamins C and E. Growth Phase There are two segments of the growth phase. The first is a rapid segment of muscle repair and growth that lasts for up to 4 hours. The second segment is the remainder of the day where proper nutrition guidelines are being met complex carbohydrates, less saturated fats--substituting with more monounsatureated and polyunsaturated fats, and healthy protein sources such as chicken, seafood, eggs, nuts, lean beef and beans. During the rapid growth phase a drink filled with high-glycemic carbohydrates and protein may be consumed. In this phase the ratio of carbohydrates to protein should be with 4 grams of carbohydrate to 20 grams of protein. However, the information and discussion in this article better prepares the aquatic fitness professional to guide and educate students about the metabolic and nutrient needs of exercising muscles. In the areas of nutrition and exercise physiology, nutrient timing is 'buzzing' with scientific interest. Ingestion of appropriate amounts of carbohydrate and protein at the right times will enhance glycogen synthesis, replenish glycogen stores, decrease muscle inflammation, increase protein synthesis, maintain continued muscle cell insulin sensitivity, enhance muscle development, encourage faster muscle recovery and boost energy levels that says it all.

| What time should you eat meals to gain muscle? The complex science, explained | This drink should contain a ratio of carbohydrate to protein and should include approximately 6 grams of protein and 24 grams of carbohydrate. Additional drink composition substances should include leucine for protein synthesis , Vitamin C and E because they reduce free-radical levels-which are a contributing cause to muscle damage , and sodium, potassium and magnesium which are important electrolytes lost in sweat. Anabolic Phase During the anabolic phase a supplement made up of high-glycemic carbohydrate and protein should be consumed. This should be a ratio of carbohydrate to protein and should contain approximately 15 g of protein and 45 grams of carbohydrate. Other important drink substances include leucine for protein synthesis , glutamine for immune system function , and antioxidant Vitamins C and E. Growth Phase There are two segments of the growth phase. The first is a rapid segment of muscle repair and growth that lasts for up to 4 hours. The second segment is the remainder of the day where proper nutrition guidelines are being met complex carbohydrates, less saturated fats--substituting with more monounsatureated and polyunsaturated fats, and healthy protein sources such as chicken, seafood, eggs, nuts, lean beef and beans. During the rapid growth phase a drink filled with high-glycemic carbohydrates and protein may be consumed. In this phase the ratio of carbohydrates to protein should be with 4 grams of carbohydrate to 20 grams of protein. However, the information and discussion in this article better prepares the aquatic fitness professional to guide and educate students about the metabolic and nutrient needs of exercising muscles. In the areas of nutrition and exercise physiology, nutrient timing is 'buzzing' with scientific interest. Ingestion of appropriate amounts of carbohydrate and protein at the right times will enhance glycogen synthesis, replenish glycogen stores, decrease muscle inflammation, increase protein synthesis, maintain continued muscle cell insulin sensitivity, enhance muscle development, encourage faster muscle recovery and boost energy levels that says it all.

This is one of the benefits of skipping breakfast — enabling larger lunches and dinners. The majority of my clients over the years skip breakfast when in a cutting phase and many choose to skip it when in a bulking phase. There is a caveat to this: for those who train fasted in the morning, I have them take a whey protein shake first to minimize the risk of muscle breakdown. More details on this in the meal timing section. For those bulking, it can get to a point where it is not comfortable or practical to eat just two meals a day because of the volume of food that needs to be consumed. Though there are likely no benefits to eating more than four meals a day, it is perfectly fine to do so if you wish. Whether you care enough about the incremental differences between 2 and 3 meals, and 3 and 4 meals, is something you have to decide for yourself. Physique professionals may wish to opt for the higher end to maximize any potential benefits. You do you. Nutrient timing is not as important as we once thought it was. There are three fairly simple rules to follow when it comes to meal timing during the day. As long as you follow them, you should be totally fine. I myself, as well as many clients, prefer to train first thing in the morning without having eaten a meal prior. If you choose to do this also, make sure you have a whey shake 30—60 minutes before you start lifting heavy so that when your body seeks amino acids the building blocks of protein , it takes them from your bloodstream rather than breaking muscle down to get them. Whey protein is better than EAA or BCAA supplementation in this scenario. It is fast-digesting a good thing in this context at a rate of 8—10 g per hour, therefore, if your first meal of the day is more than 3 hours after your first scoop was taken, take a second scoop. I prefer to have 50 g of whey in the morning rather than splitting it into two shakes. If you find yourself struggling to train with the same intensity you usually do, have 30—60 g of carbs with the shake. This can be as simple as eating a banana or two or anything you find easy to digest. Toward the end of a cut, when your liver and muscle glycogen stores are low, this could help you maintain training intensity. If you eat twice per day, make that lunch and dinner, and roughly hours apart. If you eat three times per day, make it breakfast, lunch, and dinner. As long as meals are evenly spaced, there is likely very little benefit to worrying about more specific protein or carbohydrate timing. Here are some detailed meal timing examples of when to eat, relative to when you train. This setup is the most popular with clients. They all have full-time jobs and most have families, so they choose this because it allows them to train before the rest of the day takes its toll. My preferred setup is the left column. 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. The key to success is often preparing lunch the night prior. Training in the evening is completely fine, but if you find that stuff often comes up which prevents you from leaving work early to do it, consider training in the morning. In this specific case, a slow-release protein shake like casein may be better than whey prior to bed. A pre-prepared small chicken breast would do equally well if not better, and the banana is just an example of some quick and easy carbs. Some people find that carbs make them sleepy. Breakfast eaters that feel lethargic mid-morning should consider eating fewer calories from carbs, and more calories from fats at breakfast time, and reversing this at dinner. Breakfast skippers should do this but with lunch. As an added bonus, this may help you sleep better in the evening. A small percentage of clients find that a large meal before bed disturbs their sleep. If this causes you to sweat or just otherwise feel uncomfortable, eat one or two hours earlier or reduce the calorie content of your evening meal. I do it, many of my industry friends do it, and many of my clients do it also. However, there are a few different types of intermittent fasting I. Leangains is a style of intermittent fasting developed by Swedish nutritionist Martin Berkhan. It combines skipping breakfast with fluctuating calorie and macro intake — more calories and carbs are consumed on the training days; fewer calories and carbs are consumed on the rest days. Fat intake is lower on the training days, and more on the rest days. Martin popularized the term by telling people to eat all their food within an 8-hour window. So, Leangains preceded I. Marketing and practicality, in my opinion. This is an attempt at getting more favorable calorie partitioning. More calories and carbs on the training days when they can be utilized for growth and recovery, with a low fat intake to minimize the risk of any storage. The rest days just flip it, so that the balance for the week is maintained. Probably not. Still, I offer a pattern similar to this with clients because it breaks the monotony of dieting. The majority of clients choose to do this but it is their choice, not my demand. My advice: try it, see if you like it. Why include them? They provide a helpful break from the monotony of dieting by introducing some variety in possible food options across the week. Will they be beneficial beyond that? Probably not for beginners and early intermediates, possibly for those more advanced. 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. |
| Nutrient Timing | I recommend you avoid extreme splits in macro intake as that could also compromise recovery and hamper adherence. Introduction Exercise enthusiasts in aquatic exercise and other modes of exercise regularly seek to improve their strength, stamina, muscle power and body composition through consistent exercise and proper nutrition. Rasmussen BB, Tipton KD, Miller SL, Wolf SE, Wolfe RR: An oral essential amino acid-carbohydrate supplement enhances muscle protein anabolism after resistance exercise. Type of Protein Consumed : Another component worth considering before timing is the type of protein one is ingesting — especially if the goal is to support muscle growth. 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. |
