Out of rhythm

Messed up on the eating because of a routine change - the principle is simple: eat every 3 hours and snack in between! Ended up eating chips at night because there was a 4.5 hour gap between the evening meal and dinner - albeit with a snack of apple and boiled egg white in between. Careful on this count, and even if there is a gap, mind the carbs at night and eat sensible (even if large) portions!
