After a moderate workout, you need not refuel immediately since your muscles are not really depleted. If you start to lift weight seriously, you should plan a well balanced post-workout nutrition program to help you recover, build muscle and burn fat.
Your post-workout diet should include:
- Carbohydrate. For a 150-pound athlete, carb loading for rapid recovery is about 300 calories every 2 hours for 4 to 6 hours.
- Protein. The target is about 15 to 30 grams of protein for a 150-pound athlete taken right after exercise.
Timing may be even more important than the actual amount of food. Your best bet is to time your meals to your workout.
