Rosie, a small cheeseburger is not a bad thing. It's those super-sized loaded burgers with fries & shakes or sodas that make us fat. A correct size for a cheeseburger is about the size of your palm.

If you ignore your cravings, that can lead to pigging out and eating everything in sight.

I'm a big believer in allowing yourself to eat treats occasionally for long-term weight loss. That way, when you reach your goal, you don't go crazy eating everything you "gave up" and gain it all back. The key is to learn to limit treats (even like a cheeseburger) to occasional splurges, not everyday fare.
