I was wondering since I have read that the number of fat cells in our body is determined during puberty, and that they never disappear.
Personally I reached a BMI of 31.1 when I was 16, then I went to 21.1 before turning 17. Does the fact that I have been obese in the past prevent me from ever looking really skinny if I wanted to?

No, but it will likely be harder for you to stay skinny than for someone who was never obese.
(1) It takes a lot of energy for your body to build new fat cells, because of this your body will only create new fat cells when the existing cells are already full.
(2) Empty fat cells produce a hormone that tell your brain to eat more. If you were obese in the past, then you have more empty fat cells than someone who has never been obese, and this will tell your brain you need to eat more frequently.
