Im 13 and I weigh 106 lbs and I'm pretty skinny but also around 12-15% body fat. I just started calisthenics a while ago but I just started working out consistently 2 weeks ago and started eating a lot of eggs( 3-6 a day)and I'm noticing some gains already, which is good! but I'm kind of wondering if it is possible for me to be able to make gains/gain weight while loosing fat
