LOL!! No seriously, I edited this post because it initially said "Bread is the devil" but then I realized that I would be destroyed for my carb bashing and decided that I should specify that white bread, is in fact, the devil.
But this is what I have been learning at Medical Weight Loss:
Eat protein with every meal.
Water, Water, Water
if you eat something that is unhealthy drink a few extra glasses of water to flush it out.
do not use salt, if you have to have salt use morton's light salt or something similar. Also try other seasonings for flavor.
Don't use white bread, use, like Rev said, whole grains but limit your servings of breads, pasta, etc to 3 servings a day. So that is a sandwich and about a cup of cereal.
If you like the taste of butter you can use spray butter which has no fat or use butter buds which actually tastes awesome.
Okay now that I posted all this I better practice what I preach, right?
