I am 19 yr and 5'8". so at my max I weighed about 185 lbs. Over about a year I got down to 125. I noticed something was wrong, I have loose skin. I have gained 20(bout 145) lbs back and am looking to gain more. As a baby and up until i lost the weight, I had very chubby cheeks(pinch worthy). So, if I gain more weight/fat will my cheeks fill in? And how much more fat/weight should I need to add on to fully regain my once awesome chubby cheeks. Also, at around 140-150lbs I had some loose skin.
