And how expensive is that?  Seriously, if you maintain the same, healthy weight your entire adult life you won't have to spend all your disposable income replacing clothes as you gain weight and then replace them again when your obesity means you wear your clothes out ten times as fast.  It's interesting that all the fatties obsess over the cost of salad versus a hamburger but never seem to realize all the ways that being fat robs them, from lower wages, to higher health care costs, to constantly replacing clothes and car suspensions. etc.
