For one thing, this is supposing that you'd be able to lose the extra weight... which is far from certain.
Also, by then you'll have gotten used to being fat and most likely will have gained new habits (walking less, sitting more, overeating at most meals, going for less healthy foods than before...) so I think you'll be more likely to gain more weight, whether you want it or not.
But you know what they say, right? "Once you go fat you never go back." ;-)
this was my experience... i posted elsewhere on "the point of no return" where i couldn't even lose the weight when i tried, and i was just gaining involuntarily.
looking back though, i am in the happiest place i have ever been, so no regrets yet!
