What body fat % causes excess skin? I know its not a clear cut answer, but there seems to be a point of BF % were you get excess skin, any ideas?

Not sure but I think all body fats cause excess skin since it's the skin that then gets a hard time to contract back to normal when you lose weight.

Your skin is like an elastic band. It can stretch & contract until it gets to a point it can’t contract any more. How much you weighed before surgery. How long you weighed that much. How much weight you want to lose. How old you are all affect your skin’s elasticity & how much lose skin you will end up with.

I was feeling a bit cocky about how little loose skin I had but once I started losing the last 10 kgs & surpassed my goal, it all started to droop. I don’t have a lot compared to others & I’m not contemplating surgery. But you won’t see me waving my arms about or wearing shorty shorts. My little tummy pooch doesn’t show in form fitting clothes.

One old hair band used a lot. One new band hardly used. ?

this is a very good visual thank you.

like others have said, there's not a straight answer for that. If you have a lot of weight to lose (esp 100 lbs or more), you'll most likely have some loose skin, though. How much depends on a lot of things....
