Um, hello, yeah.... Its probably rare to see a question like this pop up anywhere. But anyways, I'm 16 years of age currently weighting 124-125lbs. Est. 5'2" or something and not growing anymore. I've been eating protein, eating at least 3,000 - 4,000 calories a day, I try to stay as inactive as possible (I have to walk to school and back and I do leg exercises, that's about all the exercise I do) ,and all (almost all. Some are little snacks: chips, candy, etc.) the foods I've been eating have been healthy weight gain foods, but, I'm just not gaining any weight. I've always been skinny and my metabolism has always been fast (genetic). I've been able to gain weight I just lose it in a matter of a day or so. I don't know what I'm doing wrong I've been thinking of doing the 5,000 calorie diet challenge but I never have enough food to even try. I don't even know if I can slow down my metabolism and if i can, how? How do I keep my weight on?! Please help :( recommendations? Ideas? All will help!
