Anna, it's called the 17 Day Diet by Dr. Mike Moreno. Basically, in the first 17 days you eat lean proteins(fish & poultry), tons of vegetables, and you get 2 servings of fruit and 2 servings of yogurt a day. He says that if you restrict your fruit to before 2pm, you're less likely to convert those sugars/carbs into fat.
This first cycle is a cleansing diet geared towards getting your body to burn fat like crazy. After 17 days you go onto cycle 2 which allows you some more meat choices, some complex carbs on every other day, and I think a little cheese. I miss cheese.
I eat one of my 2 yogurt/kefir servings at night.
Man, today was tough! I went shopping and missed lunch time by 20 minutes. I thought I was going to pass out in the store. Thankfully I brought a few tofu pups with me which was just enough protein to get me home.
I find that I've got to eat 'on time' with this diet.
