Q: Should I eat the same amount on off days as I do on training days?
A: Yes. Muscle protein synthesis continues for a day or so after your last lifting session, so we want to supply the body with enough nutrition that it can recover fast. You don’t need to employ any kind of carb or calorie cycling for the workouts in The Truth About Strength Training.
Eating approximately the same amount of healthy food daily is enough, and doing it daily establishes the habit of eating a clean diet and hitting your macros, and it keeps the diet less complicated.
