I eat 1200 calories a day. The heavier you are the more calories you need but even at eating only 1200 calories I am not starving myself by any means. I hardly snack and I always eat until I am full during meals. I think its just a matter of switching WHAT you eat.

There are calucators out there that you can plug in your weight and they will tell you how many calories you need to maintain and how many to lose.

I think I read somewhere to lose one pound you need to cut out 3500 calories.

I am eating the same on Alli as when I wasn't.
I also know that going below 1200 calories a day is not good for your body.
