The best thing to do is MOVE ON. We all have days when we eat more than our bodies need, that is the rule, not the exception. In two decades of practice as a nutrition counselor, I have never met someone who did not lose weight because of ONE episode of overeating. The trouble starts when one episode stretches into an entire day, week, month – you get the picture. You do NOT need to go on a very restrictive program to compensate for over eating. But you should try to think about the circumstances that led up to the overeating — Too much tempting food around? A stressful personal or work situation? Being too restrictive with your weight loss program so that it is very hard to maintain? – So that you can try to understand the behavior and practice correcting the response the next time around.
