Here are few ideas:
Whenever I go over my limit during the day I take easy at dinner.
Either I have only salad (not even has to be little, because salad is very light). So I have a super big salad or I only eat fruits. Apples, peaches, grapes, melons. I usually eat a bite of each one.
So you kill your hunger and don’t feel so guilty.
If I crave something else. I only have one cup of sugar free gelatin. The one I buy has only 5 cal/each.
Good luck!!!
