6 Post-Workout Ideas: What to Eat to Build Muscle After Workout

Nutrition and exercise go hand by hand. If you want to optimize your performance and muscle gains, you should pay more attention to what to eat. In this post, we'll tell you what to eat to build muscle after workout.

Post-Workout Nutrition

If there's a moment your body is susceptible to changes, that's after workout.

Intense exercise compromises your muscles, and sets your body into "survival mode". And that's when nutrition comes into play.

Nutrition and training go hand by hand. When it comes to building muscle, a correct nutrition will provide all necessary nutrients to repair, maintain, and create muscle mass (1).

Although diet should be looked as “all day” thing, nutrition around the workout gains more importance. Pre-, intra-, and post-workout nutrition is a key factor of sports performance, muscle recovery, or muscle anabolism (2)

Post-Workout Nutrition Helps you Recover from the Workout

During and after intense exercise, your body enters in a catabolic state. You expose your body to unusual efforts. Muscle fatigue is built up, and energy levels keep going down.

This leads to elevated cortisol, less oxygen available, low insulin, and higher rates of muscle protein breakdown (3). However, nutrition can help you minimize all these unwanted effects.

Based on what you eat after workout, you can optimize muscle recovery and ressemble to the green line of the graph.

Carbohydrates and protein post workout show to increase substrate availability, blood glucose levels, and decrease cortisol. In other words, it shiftes your body from a catabolic to an anabolic state (4)

Post-Workout Nutrition Optimizes Muscle Anabolism

During intense exercise (e.g: weightlifting), muscle protein breaks down and muscle glycogen is used up. This catabolic state will be the signal for telling our body that we need to create more muscle mass in order to survive and evolve

To build muscle, you need to get out of that catabolic state. And the best way to do it is through nutrition. Post-workout nutrition helps you restore glycogen stores, repair the damaged protein, and hopefully create a bit of new muscle mass.


What to Eat to Build Muscle After Workout

Depending on what you eat after workout, the anabolic response will be greater (or not). Playing with the three macronutrients of your diet, we can design the perfect post-workout meal.

Now, let's look at the impact of each of the macronutrients after workout!


Protein is the most important macronutrient for muscle building (5). Although the RDA recommends 0-8-1.2 g/kg, higher doses of 2-3 g/kg of daily protein show to be better for muscle building and body composition (6)

During intense exercise, muscle is compromised and muscle protein breakdown increases (7). Protein after workout provides all amino acids to repair and create muscle mass (8)

protein after workout

Protein after workout increases muscle protein synthesis (MPS) (9). In this study, they investigated different doses and sources of protein and their effect on the MPS (10). Here, we can conclude the following:

  1. The optimum protein dose after workout is 20-40g
  2. The anabolic response of whey protein is greater than that of plant protein. That problem can be overcome by increasing the amount of plant protein used.
  3. Protein intereacts with other nutrients, and taking a mixed meal rich in micronutrients can prolong the effect of protein after workout


High-intensity exercise requires of a lot of energy. Weightlifting, powerlifting, resistance training,... are all dependent on the glycogen stores in our body.

As we exercise, glycogen stores are emptied out (11). When glycogen is used up, performance starts to decrease, as we don't have more substrate to create energy.

Exercise energy systems

Once you are done with your workout, your body sits in a low-energy status, which is not good for muscle growth. To overcome this problem, professionals recommend carbohydrates (CHO) intakes of 1-1.5g/kg/h during the first 2h after the workout (12)(13)

Carbohydrates post workout can provide nutrients to restore glycogen stores, stimulate insulin, and increase the anabolic response (14)


Fat intake after workout is not the most interesting thing to do. It doesn't seem to influence the anabolic response nor muscle recovery, but it doesn't make any harm either.

A lot of people think fats after a workout slows down digestion and inhibits the absorption of nutrients. It may slow down the digestion, but that doesn't mean the nutrients are not absorbed. In fact, whole milk after workout is more effective than skimmed milk (15), and the same happens with whole eggs (16)

Post-Workout Meal Ideas

Now you now what to eat after workout. High-protein, high-carbs and rich in micronutrients meal. Doing that, you'll be optimizing the anabolic response, and muscle recovery.

These are some ideas you can take as your post-workout meal!
