Dropping below 1,200 caloroies a day can cause lots of problems. It can actually fool your body into thinking it is starving and you will slow down on the burning of calories. It shouldn't be done without a medical OK.
I get really concerned when I see people losing 20+ pounds in a month. A healthy weight loss should be 1 to 2 pounds a week.
Go online and Mayo Clinic has a decent diet that can be used to jump start a diet. It is based on the food pyramid.
MJ, please be careful. The world needs you. Carol
