HCG diet

So I'm doing the HCG diet and today was the first day when I was supposed to eat only 500 calories of certain food. I did ok concidering I havent gone food shopping in a while and don't have all the right food to eat. I went over by about 150 calories, but I'm still starving! Hopefully after I go shopping for food and can actually eat something more filling, it won't be so bad. We'll see if I start losing weight soon, it will be easier to stick with it.
