Janesays....somehow I never saw your post earlier! Sorry!
I hope you are sticking with it so far! When I first started SDB I did not have a ton of energy, but that faded pretty quickly. I do eat a ton of veggies along with all the healthy protein and cheese. I think this is a pretty balanced way of eating, and that may be why you aren't hungry or feeling weak.
The ricotta is good for you! You need your calcium, and since milk is out in phase 1 this is a great way to get it. Plus you need something indulgent to enjoy! You CAN eat 3 meals, 2 snacks, ricotta desert and a 75 cal treat and lose weight! So don't feel guilty about eating what your body needs.
If you don't eat enough you know what will happen...your bod will just hang on to the fat even harder! And that is NOT what we want!
SBD has really helped me develop a healthy relationship with food. The book does have quite a few inconsistancies, so come here and ask questions...we're all glad to put in our 2 cents worth!
