hCG Meal Plan

So I was talking with a friend who is on the hcg diet, and she told me that she has last 9 pounds so far on the diet (she is on day 10). While this rate of weight loss is definitely very average, it is weird because she is drinking diet sodas (about a can a day). She said that she just couldn't stand the headaches being caused by withdrawal from caffeine.

Everything that I've ever heard about the diet suggests that you shouldn't be able to drink soda (even diet soda) this and still lose weight. She has done it though, and is loosing just over a pound a day (10 - 2 days of loading = 8 days of the very low calorie diet). Anyway, if you have any experience with this, let me know in the comments below!
