I'm 18 years old, male. I weighed 150 last year, now I'm 125. I have skinny forearms and small hands and feet. But I'm 5'9 tall. I was malnourished during the age of the start of puberty and my growth was stunted. My muscles seem to be slowly getting bigger even though I've lost weight. Everything seems to be caught up on my puberty except my bone structure size and muscle size. Am I stuck like this?
