Nope, you're wrong.

According to this article on LiveScience, "you're stuck with the number of fat cells you have acquired by about age 20".

Excerpts from the article:
"The researchers knew that (fat) cells were dying and being replaced over time. [...] The scientists also found that about 10 percent of fat cells were replaced every year whether or not a person was obese.

[...] Another aspect of the study revealed that the total number of fat cells per person remained relatively constant over time. Even extreme weight-loss strategies, such as bariatric surgery, did not reduce the number of fat cells in study subjects. [...]

If you already have more fat cells from adolescence than other people, "it's harder to become thin," Buchholz [a researcher] told LiveScience.

*SIGH!!!!*

There's only one solution: liposuction!
If only it weren't so expensive ...
