That depends on several factors including your age, sex, and weight. But usually women need at least 1200 calories and men need at least 1500 calories per day just for survival. If your body doesn't get that it will go into starvation mode and YOU WILL NOT LOSE WEIGHT! If you do you would be losing it in valuable muscle tissue and organ weight. Eventually your organs would begin to shut down. To lose weight you should find your Basal Metabolic Rate (BMR) to learn how many calories you are burning each day without exercise, count the calories you eat each day, and exercise to lose enough calories to bring you to whatever your minimum is. Example: if youre BMR is 1800 you can eat 1800 calories per day to maintain your current weight. If you want to lose all you have to do is eat less than 1800 calories. 3500 calories equals 1 pound so you could safely eat 1300 calories per day and to lose 1 pound per week. Or, if you would prefer to eat more you could eat 1450 calories, burn 150 and you still "net" out to 1300 per day. You could even burn 250 calories to get to 1200. That's 4200 calories or 1.2 pounds per week. Just be sure to leave you body the minimum it needs to function on! And make sure you are selecting healthy foods with lots of nutrients and vitamins to keep you healthy!
