I am posting this here because its more of a technical question than a LC question.

Now, from what I understand... Fat cells grow and grow until they get to a certain size and then they split and grow some more.

Now when we lose weight our fat cells shrink but they never go away, so that after your fat cells split a few times, no matter how thin you get, you will always have more fat cells than someone else who has always been thin (unless you get liposuction, which is the only way to get rid of fat cells from what I understand)

My question is this... Lets say that you gained 50 lbs and your fat cells split, then lets say you lost the 50 and then regained the same 50. Would your fat cells split again?

Basically will yoyo dieting increase the number of fat cells you have every time you put the weight back on? Or will the same cells just expand and shrink, since youve already been that weight at one point?
