For me I can eat 1000 to 1200 calories and lose weight. And depending on exercize I can eat around 1400-1700 and stay stable. My doctor was okay with me eating as low as 1000 calories as long as I didn't go below and didn't get lower than 112 lbs. Now I've become good at just keeping an eye on my weight and what I eat to try to be healthy. I hope you don't mind me asking, but how much do you weigh? Many people think they are fat but arn't really and I was just trying to get an idea of what your calorie consumption should be.
