I'm a 15 yr old, 5ft 105 lbs female. I have been eating about 1300-1500 cals a day and i've gained weight. I don't understand. The calculators online say that this is my basal metabolic rate. I can't seem to lose weight and it's frustrating when everyone else around me is thin and eats all they want. Ik 105 is a healthy weight, but it just seems too much for my amount of consumption. I just need help - i want to lose 5-10 lbs because I very much despise my body. Anyway, I'm at a lose. I've heard that starvation mode was a thing and calculators tell that I need about 1800 to maintain 95 lbs, but I'm terrified to go up that high, seeing as I'm already a bit chubby to begin with. I don't know what to do. I don't have any metablic disorders and a doctor told me I'm producing all my thyroid hormones, so I don't get it. Please help.
