susan, how are you doing?
I have learned that-as hard as it is to accept- eating and feeling satisfied contributes to weight loss. Starving ourselves (fasting) does nothing but cause our bodies to hang onto everything and screw up our metabolisms.
When I eat less than my daily pp allowance and don't go into the weeklies, I don't see much loss. Often before making goal I've gone in expecting to see a gain due to feeling like I couldn't possibly lose- I ate too well and felt too satisfied....only to have a good loss.
If you follow the program it really does work. It's just hard getting past the feeling that we have to starve ourselves to lose weight but that never works in the long run. It always made me feel deprived and started off the "when I've lost xx pounds, I'm going to eat a Whopper, a donut, ice cream, etcetc...." in my head which always lead to regaining.
