I used to be fatter and after I lost weight I had stretch marks

yes but I don't know how fat you are/were

The long head of the tricep also has a tendency to be flabby when relaxed which might look like loose skin if you are paranoid about it

It's just loose skin, don't be a baby about it and as long as you eat to maintenance it should easily shrink.

Should have started with cardio. But no one listens to me.

loose skin doesn't shrink, especially if it's already hanging

I can't imagine plastic surgery wouldn't help a little bit if you're that self-conscious.

Lmao for good reason

Walking at that weight would have made fat slowly dissipate and with much less flap. Some of you guys are really stuck in meme world.

in all fairness, you can get so fat you have loose skin regardless of how slow you lose or how you start

Very true. Good point.

You might be able to fill it out with muscle a bit if it's not anywhere near as bad as that.
Still, you're pretty fucked if you're a woman who was once fat and has this issue. The arms are always one of the worst and most difficult areas for women.

If it's close to being as bad as the picture, you're probably pretty screwed and would need surgery at that point.

Pretty sure it's fat OP
If it was just skin it would be wrinkly but not hanging

I'm a man and the problem is I have no idea if it's loose skin or fat, as the change has been so gradual (over 4 years).

Seems more like stubborn fat than loose skin
