Peanut Butter for Building Muscle

Many bodybuilders and fitness enthusiasts turn to peanut butter for building muscle. The American Council on Exercise notes the importance of meal timing for optimal performance and quick recovery. They recommend consuming 15-20 grams of muscle-repairing protein and 5-10 grams of appetite-satiating fat in a post-workout meal.

A core benefit of consuming peanuts or peanut butter after working out is the high protein content, which translates into a hefty dose of amino acids. Protein is made up of amino acids, which play a vital role in building muscle.

A small June 2017 study with just 10 participants published in Frontiers of Physiology found that men who consumed amino acids after a workout had 22 percent greater muscle protein synthesis than men who did not. However, peanut butter does not contain all of the essential amino acids and should be combined with other proteins, such as legumes and grains.

After your workout, no need to rush home and chug a protein shake. The International Society of Sport Nutrition suggests consuming high-quality protein up to two hours after a workout. Peanut butter can be eaten as a snack after a workout, but it does not constitute a high-protein meal by itself.
