It's true that significant fat loss will result in some loose skin, most (or all) of which should tighten up over time.
But only people who see you naked will see the loose skin. Everyone else will see a thinner person. So the answer is no - weight loss will NOT "only" result in loose skin appearance wise.
I lost 70+ pounds over 10 years ago (at age 32). I have fully visible abs and am at about 10% body fat. When I do pushups, I have a tiny bit of loose skin that hangs down off my belly that I'm pretty sure wouldn't be there had I never been so heavy, and that I'm fairly certain will never go away. But if you saw me shirtless at the pool, you'd never know it was there. Here's a pic of me from a few months ago - you tell me: did my fat loss "only" result in loose skin?
