If you really want to snack something, you better opt for a responsible snack, for example a slice of chicken fillet or skimmed yoghurt. Why snacking in the evening is not so good There are many overweight people who have problems keeping control of sniffs later in the evening and who commit all kinds of unhealthy and tasty things. If you eat shortly before you go to sleep, these calories will be burned less as a result of the body's resting position. This ensures that your body converts this extra energy into fat.
