A member asked:
Will there be rapid weight loss with extreme calorie restriction (under 1000 a day) or will it slow the metabolism?

Dangerous: It will let body use essential muscle for calorie with very high risk for developing sudden heart attacks, loss of muscle in gut leading to acute bowel problems and if you are a diabetic developing diabetic ketoacidosis - diabetic coma be very careful.

Yes and yes: Very low calorie diets do allow rapid weight loss. The decrease in metabolism is temporary and is the bodiy's attempt to compensate. Programs like medifast can help kickstart a weight loss effort and then transition to a healthy eating program, exercise, and regular support and encouragement/accountability.

Ive been working out (boxing and Pilates), as well as walking for 3 weeks. Ive always had a very poor metabolism (or at least difficulty losing weight), but I havent lost even one pound. I am fine with slow progress, but not zero progress. My concern is that I might not be taking in enough calories for my size. Im 56 and 291 pounds. Ive been eating between 950-1100 calories a day.
