Here's a tip to help you avoid overeating...
Go ahead and eat what you like. Anything you're craving, or hungry for. Eat very slowly, and put the fork or spoon down between bites.
While you're eating, look for a very subtle feeling of fullness. It's a really small signal of satiety that you may not be used to noticing, unless you're waiting for it.
Once you feel it, STOP EATING. Get up from the table and go into the other room. Throw the excess food away--or wrap it up for tomorrow. If you're with company or at a restaurant, excuse yourself and go to the restroom. Have someone take the food away from the table. Take five minutes. Do something else. It also helps to say a prayer and ask God for help to not overeat.
