Why should I eat protein after I exercise?

F. Michael Gloth, III
Geriatric Medicine
Certain foods should be eaten soon after you exercise, in order to help your body form new muscle. Specifically, you should eat a substantial amount of protein -- often 10-20 grams -- within 30 minutes of completing a rigorous exercise session ("rigorous" is any exercise session that gets you breathing heavily). Protein helps build muscle and stops existing muscle from being broken down as a source of energy, because, similar to fat, muscle can be used to generate energy in the body. Many of you will choose a protein energy bar, based on the amount of protein on the package label.

A post-exercise protein "load" helps improve muscle strength and energy expenditure, while preventing the formation of fat. In other words, the timing of eating protein makes it easier to have a leaner, stronger body.
