Not fat but feel like it
I only weight 140, which seems insanely skinny, but I dont feel like it. I have a fat roll on my belly and pretty big legs, so I feel chubby. I have a friend that weights 160 and looks super skinny, more than me. It doesnt make much since to me, I dont wanna really lose much more weight cause im already pretty small, but I dont want to have 'flab anywhere on my body.
Your friend probably has a lot of muscle, where you may lack it. Try gaining muscle not losing weight.
