How many calories to gain weight?
Hello, I have some quick questions to ask. First of all I am a 19 year old girl, I am 5'5 and I currently weigh 105 lbs. (I know that is slightly underweight) I started off on myfitnesspal eating around 1250 calories last year, this January I increased to 1350, and just last week to 1400-1450. My weight keeps very slowly…
