The result that the number of fat cells is set in adolescence and remains constant through adulthood, by the bodies fixed fat cell replacement rate boggles my mind.

I have questions about pushing the limits of this.

The summary talks about people who were overweight in adolescence. What about a person who was lean in adolescence? How much weight would they have to gain in later adulthood to change the number of fat cells? Or would they change at all? Could you balloon up by over a hundred pounds and the number would remain fixed? Astonishing!

Also, what about methods that physically remove actual fat cells rather than deflating them, like liposuction. If the cell replacement rate stays fixed at 1-for-1 does that mean you've fixed the problem forever because you have less existing fat cells and they only replace themselves? Or does it mean that your body has some sort of baseline fat cell count, and after time, your fat cell number will be back at what it was before liposuction?

I'd love to see more information on this!!
