How much time after lunch can I go to the gym?

Although there is no specific rule, when referring to the standard full lunch you need to leave 3-4 hours to pass before going to the gym. In most cases if you feel your stomach very «heavy» then you can understand that its not a good idea to start exercising. If you intend to go the gym, it is better to eat something light (eg a toast with 1 cup natural juice or milk) and leave 1-2 hours to pass before exercising. Of course, always the time you leave between food consumption and exercising depends on the intensity and duration of training. The same applies for food quantity.
