Post-Training Nutrition: What and When to Eat After Training

Written By Anna Estes

This post will focus on post-training nutrition and brings our nutrient timing series to a close for now. If you missed the previous blogs on Pre-Training Nutrition and Intra-Training Nutrition, I recommend checking them out for a detailed description of what/when to eat before and during training sessions. 

Your training sessions provide an important stimulus for improving athletic performance, but did you know that post-training recovery also plays a critical role in performance? During a training session, particularly those of higher intensity and/or longer duration, your body can experience muscle damage, fluid loss, and energy depletion. Post-training recovery should therefore focus on things like muscle repair, glycogen replenishment, and rehydration (1). All of these processes can and should be addressed with your post-training nutrition. Some people find it helpful to think of the “3 Rs of recovery nutrition” - refuel, repair, and rehydrate. Incorporating appropriate recovery nutrition promotes physical performance, helps reduce injury risk, and supports your long-term health. 

Refuel Energy Stores with Carbohydrate

If you’ve read the Pre-Training Nutrition and Intra-Training Nutrition blog posts, you’re probably aware that carbohydrates are the body’s primary source of energy, and that this is especially true during high-intensity activity. Muscle and liver glycogen, a storage form of carbohydrate, can be mobilized during exercise to meet energy demands. Longer duration and/or higher intensity activity reduce glycogen stores more than shorter/low intensity activity. Consuming carbohydrates after exercise helps to restore energy, replenish glycogen stores, and prepare the body for your next training session (1).

The timing and amount of carbohydrate you consume after a training session depends on the amount of recovery time that you have. If you have less than ~8 hours until your next training session, you should try to replenish glycogen stores quickly by consuming 1–1.2 grams of carbohydrate per kilogram of body weight per hour (1–1.2 g/kg/hr) for the first 4 hours post-exercise, then resume normal dietary habits for the remaining time until your next training session (2,3). If you have more than 8 hours to recover, you can take a less aggressive approach with glycogen replenishment. Aim to consume about 1 gram of carbohydrate per kilogram of body weight (1 g/kg) within about ~1–2 hours of finishing a session. This can come in the form of a post-training snack, meal, or combination of both. In theory, meeting daily carbohydrate needs should be sufficient to restore muscle glycogen for those who have greater recovery time, as muscle glycogen stores will typically normalize within ~24–36 hours provided that daily carbohydrate intake is sufficient; i.e. not restricted, like on a low carbohydrate diet (3,4,5). However, athletes have elevated total daily carbohydrate needs and research shows many athletes fail to meet carbohydrate recommendations and misjudge their intake relative to their needs (6). Therefore, a dedicated post-training snack or meal containing 1 g/kg carbohydrate can be a practical strategy to help support adequate total daily carbohydrate intake and short-term training recovery.

Your pre and intra-training carbohydrate choices should be low in fiber to facilitate quick glucose delivery to tissues and minimize the risk of gastrointestinal distress during activity. Since those constraints no longer apply after a training session, opt for complex, fiber-rich carbohydrate choices, such as whole grains, beans, lentils, fruits, starchy vegetables, etc., unless you have back-to-back sessions or limited recovery time and rapid glycogen restoration is needed.

Repair Muscle Tissue with Protein

Exercise can cause micro-tears in muscle fibers, and while this may sound harmful, it’s actually an essential part of muscle strengthening and exercise adaptation. Muscle protein synthesis is the biological process through which cells produce new proteins to replace those that were damaged during exercise. Post-exercise protein intake helps provide the body with amino acids, or the “building blocks” that are required for muscle protein synthesis and repair. After exercise, aim to consume between ~0.25–0.4 grams of protein per kilogram of body weight (~0.25–0.4 g/kg). For many people, this will fall in the range of ~20–40 grams of protein depending on body weight (5,7).

If you want to get even more specific, consider opting for a protein source that contains at least ~2–3 grams of leucine, which is a branched-chain essential amino acid that plays a key role in stimulating muscle protein synthesis (8). In general, animal source proteins tend to have a higher leucine content than plant proteins, however, this is not always the case, and plant proteins can still be an effective recovery nutrition option (9). 

If you opt to use a protein powder as part of your recovery nutrition, consider choosing whey protein. Whey protein is a high-quality protein that has a high concentration of essential amino acids (including leucine) and is rapidly digested (5). If you are a plant-based athlete, soy protein or a blend of different plants (e.g. rice + pea) can also effectively support recovery, especially when total daily protein intake is sufficient. Regardless of the type of protein powder, select one that has some type of third-party testing certification like NSF Certified For Sport or Informed Sport to help ensure better quality and safety.

Alternatively, if you’re in need of a quick and convenient option, but you don’t want to use protein powder, you could consider a ready-made protein shake. You can purchase these at most grocery stores and there are typically both dairy-based and plant-based options available depending on your dietary preferences. Examples include Orgain, OWYN, and Core Power (by Fairlife), just to name a few. If you do consume dairy, you could also try a high protein drinkable yogurt (e.g. Oikos, Chobani) as a quick recovery nutrition option. Don’t forget to pair these protein sources with some carbohydrates.

Rehydrate with Fluids

During training sessions, we lose fluid through sweat and respiration, and it’s important to rehydrate and replace these losses upon completion, as dehydration can have a wide range of negative consequences for the body. For most people engaging in a majority of activities, resuming normal drinking and eating practices should be adequate to replace fluid and electrolyte losses prior to the start of the next training session. However, if dehydration is severe (e.g. >5% of body weight lost) or rapid rehydration is required, it’s recommended for athletes to drink 1.2–1.5 liters of fluid for each 1 kilogram of body mass lost during training (5,10). Plain water, sports drinks, and other types of fluids are all effective rehydration options, though fluids containing sodium may better support fluid retention when rapid rehydration is needed (5).

Timing Your Recovery Nutrition

You may have heard that you need to eat within 1 hour of finishing your training session to make sure you take advantage of the “anabolic window,” particularly with respect to protein ingestion. The idea of an “anabolic window” is debated and scientific research on this topic is evolving. While early research emphasized a narrow post-exercise window of opportunity for maximizing muscle protein synthesis, more recent evidence suggests that this window is broader than once believed, especially when total daily protein intake is adequate (11,12). Newer research suggests that total daily protein intake is the primary driver for muscle adaptation and repair, and specific protein distribution/timing plays a secondary role (13). In other words, it’s not necessary to get too hung up on eating protein immediately after finishing your training, particularly when balanced meals/snacks are spaced regularly throughout the day. One exception may be if you’ve completed your training in a fasted state. In that case, you should prioritize refueling sooner rather than later, as your body may already be in a depleted state. 

While it’s not absolutely essential to refuel with protein within 1 hour of finishing training, it is generally a good rule of thumb to get into the habit of at least planning to refuel with a post-training meal or snack (containing protein and carbohydrates) within ~1–2 hours to support recovery. From a practical standpoint, athletes and active individuals have higher overall nutrition needs, and incorporating post-training nutrition is a convenient way to help meet elevated daily carbohydrate and protein targets while supporting recovery from the demands of training.

Recovery Nutrition Examples

Recovery Snack Examples

  • Smoothie, e.g. milk (or plant-based milk) + banana + oats + protein powder (or Greek yogurt) + peanut butter

  • Chocolate milk or ready made protein shake + banana

  • Greek yogurt with apple and honey

  • Peanut butter and jelly sandwich with a glass of soy milk 

  • Cottage cheese with fruit and pretzels on the side 

Recovery Meal Examples

  • Burrito bowl with rice, veggies, and protein of choice (e.g. chicken, beef, pork, tofu, beans)

  • Egg and cheese bagel sandwich with a latte 

  • Salmon, sweet potato, and roasted broccoli 

  • Stir fry noodles with veggies and protein of choice (e.g. chicken, shrimp, beef, tofu) 

  • Pesto pasta with kale and ground turkey meatballs

  • Turkey sandwich or wrap with an apple on the side 

Key Takeaways

Post-training nutrition plays an important role in supporting recovery, adaptation, and overall performance. After exercise, your nutrition priorities can be simplified into the “3 Rs” –

  • Refuel glycogen stores and energy levels with carbohydrates

  • Repair muscle tissue with protein

  • Rehydrate by replacing fluid losses

Refueling with recovery nutrition is especially important after longer and/or higher intensity training sessions, or when you have limited time to recover before your next session. Otherwise, a balanced meal or snack that includes carbohydrates, protein, and fluids is typically sufficient to support recovery and prepare you for your next session.
