If it is mainly aerobic, it is recommended not to eat before exercise, and to supplement protein and a small amount of carbohydrates after exercise! ! !

If it is mainly anaerobic exercise (lifting iron or something), it is recommended to supplement a small amount of carbohydrates before exercise.

But whether you exercise or not, don't eat more at night, eat as early as possible, and don't eat greasy food.

Finally, if you often do aerobic exercise, you must remember to supplement protein, which is very important, otherwise your muscles will be lost.
