Nutrient timing for nutrient utilization -
See how to count macros to keep your nutrient timing as effective as possible. Supplemental nutrition may not be necessary during shorter or less-intense activity bouts. If so, carbohydrate consumption should begin shortly after the start of exercise.
One popular sports-nutrition trend is to use multiple carb sources with different routes and rates of absorption to maximize the supply of energy to cells and lessen the risk of GI distress Burd et al.
Consuming ounces of such drinks every minutes during exercise has been shown to extend the exercise capacity of some athletes ACSM However, athletes should refine these approaches according to their individual sweat rates, tolerances and exertion levels.
Some athletes prefer gels or chews to replace carbohydrates during extended activities. These sports supplements are formulated with a specific composition of nutrients to rapidly supply carbohydrates and electrolytes.
Most provide about 25 g of carbohydrate per serving and should be consumed with water to speed digestion and prevent cramping. To improve fitness and endurance, we must anticipate the next episode of activity as soon as one exercise session ends. That means focusing on recovery, one of the most important-and often overlooked-aspects of proper sports nutrition.
An effective nutrition recovery plan supplies the right nutrients at the right time. Recovery is the body's process of adapting to the previous workload and strengthening itself for the next physical challenge.
Nutritional components of recovery include carbohydrates to replenish depleted fuel stores, protein to help repair damaged muscle and develop new muscle tissue, and fluids and electrolytes to rehydrate.
A full, rapid recovery supplies more energy and hydration for the next workout or event, which improves performance and reduces the chance of injury. Training generally depletes muscle glycogen.
To maximize muscle glycogen replacement, athletes should consume a carbohydrate-rich snack within this minute window. The recommendation for rapidly replenishing glycogen stores is to take in foods providing 1. For a pound athlete, that equates to between 68 and g of carbs or ~ 4. Since this can be difficult to consume in whole foods shortly after activity, liquid and bar supplements may be useful and convenient after exercise.
Consuming smaller amounts of carbohydrates more frequently may be prudent if the previous recommendation leaves the athlete feeling too full. Bananas are a great source of healthy carbs , if you didn't know!
Muscle tissue repair and muscle building are important for recovery. Whether you're focusing on endurance or strength training, taking in protein after a workout provides the amino acid building blocks needed to repair muscle fibers that get damaged and catabolized during exercise, and to promote the development of new muscle tissue.
Recent research has further demonstrated that a similar amount of protein approximately g after resistance exercise may even benefit athletes on calorie-restricted diets who also want to maintain lean body mass Areta et al.
It is important to note that some literature emphasizing extremely high levels of protein intake-well beyond these recommendations-for strength training may be dated and lack quality research Spendlove et al.
Virtually all weight lost during exercise is fluid, so weighing yourself without clothes before and after exercise can help gauge net fluid losses. It is important to restore hydration status before the next exercise period.
However, water may be all you need if exercising for less than 1 hour at a low intensity. While these recommendations are a good starting point, there are no absolute sports nutrition rules that satisfy everyone's needs…so paying attention to how you feel during exercise and how diet affects performance is of utmost importance.
You may have to use different timing and alternate routines to create a nutrition and exercise combo that works best. Timing certainly is critical in sports nutrition, and optimizing that can make all the difference! Read also: Muscle Clocks - The Value of Synchronized Training.
Fast fix: You can positively affect event outcomes by eating the right foods in the right amounts at the right times. A good way to start recovery is to consume a snack with carbohydrates and a moderate amount of protein, plus fluids and sodium, within 30 minutes after exercise.
If you have no appetite post-exercise, a recovery beverage may be a good option. To recover quickly and completely, your body needs healthy fuel like the choices shown here-beginning within 30 minutes of your session's end.

Nutrition American Fitness Magazine Nutrient Timing: Pre and Post-Workout Questions Answered! Does Fast-and-Burn Work for Weight Loss?
Training and Nutrient Timing Before Events A diet plan is crucial for maximizing daily workouts and recovery, especially in the lead-up to the big day. WHY Eat Before a workout? WHAT to Eat Before a workout The majority of nutrients in a pre workout meal should come from carbohydrates, as these macronutrients immediately fuel the body.

What About PROTEIN? REHYDRATE Effectively With Fluids and Sodium Virtually all weight lost during exercise is fluid, so weighing yourself without clothes before and after exercise can help gauge net fluid losses. Listen to Your Body's Timing Signals While these recommendations are a good starting point, there are no absolute sports nutrition rules that satisfy everyone's needs…so paying attention to how you feel during exercise and how diet affects performance is of utmost importance.
Brad Schoenfeld also arrived at this conclusion, summarizing that daily protein and nutrient intake is the priority In short, if you meet your total daily needs for protein, calories and other nutrients, the anabolic window is less important than most people believe.
Two exceptions are elite athletes or people who train several times per day, who may need to maximize fuel replenishment between sessions. The anabolic window is a period of time after workouts that is said to be crucial for nutrient intake. Depending on your goals, the correct timing for taking certain supplements may actually aid performance For example, performance-enhancing supplements like caffeine must be taken at the right time in order to have the proper effect This also applies to food.
A well-balanced, easily digestible meal eaten 60— minutes before a workout may improve performance, especially if you have not eaten for several hours In contrast, if your goal is fat loss, training with less food may help you burn fat, improve insulin sensitivity and provide other important long-term benefits 17 , Hydration is also closely linked to health and performance.
Many people tend to be dehydrated before working out, so it may be important to drink around 12—16 oz — ml of water and electrolytes before the workout 19 , 20 , Additionally, vitamins may affect workout performance, and may even reduce training benefits. So although vitamins are important nutrients, it may be best not to take them close to your workout Nutrient timing may play an important role in pre-workout nutrition, especially if you want to maximize performance, improve body composition or have specific health goals.
Instead, what you eat for breakfast has become the hot topic. Many professionals now recommend a low-carb, high-fat breakfast, which is claimed to improve energy levels, mental function, fat burning and keep you full. However, while this sounds great in theory, most of these observations are anecdotal and unsupported by research Additionally, some studies show that protein-based breakfasts have health benefits.
However, this is likely due to the many benefits of protein, and timing probably does not play a role Your breakfast choice should simply reflect your daily dietary preferences and goals.
There is no evidence to support one best approach for breakfast. Your breakfast should reflect your dietary preferences and goals. This reduction of carbs simply helps you reduce total daily calorie intake, creating a calorie deficit — the key factor in weight loss. The timing is not important.
In contrast to eliminating carbs at night, some research actually shows carbs can help with sleep and relaxation, although more research is needed on this This may hold some truth, as carbs release the neurotransmitter serotonin, which helps regulate your sleep cycle.
Cutting carbs at night is not a good tip for losing weight, especially since carbs may help promote sleep. However, further research is needed on this. Instead, focus your efforts on consistency, daily calorie intake, food quality and sustainability. Whether your diet is high or low in carbs, you may wonder if timing matters to reap their benefits.

A Brief History of Nutrient Timing. However, a closer look at the research shows that these findings are far from conclusive, and have two significant limitations 1 , 5 : Short-term blood markers: Many of the studies only measure short-term blood markers, which often fail to correlate with long-term benefits 6.
Ultra-endurance athletes: Many of the studies follow extreme endurance athletes, which do not necessarily represent the average person.
Bottom Line: Nutrient timing has been around for several decades. The Anabolic Window: Fact or Fiction? The theory is based on two key principles: Carb replenishment: After a workout, an immediate supply of carbs helps maximize glycogen stores, which can improve performance and recovery.
Protein intake: Working out breaks down protein, so post-workout protein helps repair and initiate growth by stimulating muscle protein synthesis MPS. Carb Replenishment One main aspect of the anabolic window is carb replenishment, since carbs are stored in the muscles and liver as glycogen.
Protein Intake The second aspect of the anabolic window is the use of protein to stimulate muscle protein synthesis MPS , which plays a key role in recovery and growth. Bottom Line: The anabolic window is a period of time after workouts that is said to be crucial for nutrient intake. Nutrient Timing Before You Train.
The pre-workout window may actually be more important than the anabolic window. Bottom Line: Nutrient timing may play an important role in pre-workout nutrition, especially if you want to maximize performance, improve body composition or have specific health goals.
Nutrient Timing at Breakfast. As with the anabolic window, the breakfast myth is not supported by research. Bottom Line: There is no evidence to support one best approach for breakfast.
Nutrient Timing at Night. This is another diet myth, promoted by celebrities and magazines around the world. Bottom Line: Cutting carbs at night is not a good tip for losing weight, especially since carbs may help promote sleep. Does Nutrient Timing Matter?

| International Society of Sports Nutrition position stand: Nutrient timing | Muscle hypertrophy occurs during this phase. Muscle glycogen is also fully replenished. While timing nutrition may seem like a lot of work, it does get easier with practice. Plus, there are quite a few benefits in timing your meal or snack. Nutrient timing can help maximize muscle growth. A study 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. You can offer this advice yourself by becoming a certified nutrition coach. Through a partnership with Precision Nutrition, ISSA offers Nutrition Coach certification. This course teaches you how to determine optimal fat, carbohydrate, and protein intake for individual clients. You also gain access to more than 40 nutrition coaching tools. By becoming an ISSA Nutritionist, you'll learn the foundations of how food fuels the body, plus step by step methods for implementing a healthy eating plan into clients' lifestyles. Farouk El-Sabban. EC Nutrition 2. Yang, F. 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. To replenish fuel stores glycogen , replace fluids and electrolytes, and repair damaged tissue. Tip: Measure your starting weight before you eat, dress, or exercise. Tip : Check your post-exercise weight and calculate change in weight. Adjust timing and amount of carbs to match schedule, activity, and preference. Tip: Choose foods low in fat and fiber to prevent stomach upset. Avoid new or unfamiliar foods the day of an event, race, or mission. Experiment during training instead. Fuel : For exercise up to 2. Choose from easily digestible carbs, such as fruit, grains, and sports drinks. Tip: Try different types or brands of sports drinks to find what works best for you. Or make your own. Fluid : 20—24 fl oz sports drink or water per pound lost during exercise; or drink until urine is pale yellow. Fuel : Choose a meal containing carb-rich foods and 15—30 grams protein. Or eat a snack if the next meal is more than 2 hours away. Tip: Replace more water and sodium than was lost. Look for moderate or high sodium options at your dining facility. To prevent dehydration by replacing fluids and electrolytes lost through sweat, and to provide carbs to refuel muscles and maintain blood sugar levels. To restore fuel glycogen , replace fluids and electrolytes, and repair damaged tissues. Fluid : 16—32 fl oz per hour water, sports drink, or a mixture of both. Fuel examples at least 1 — 2 per hour :. Fluid : 20—24 fl oz per hour water, sports drink, or a mixture of both. Nutrition and menu standards for human performance optimization. Washington, DC.
