Eat less food. Once I got into my thirties it became very clear that my metabolism was slowing down and I wasn't going to be able to continue to eat as much as I used to. Three square meals a day is bullshit and I think this is why post-middle-age folks tend to be so paunchy. My advice (based entirely off my anecdotal experience) is to switch to the General McChrystal diet: Eat one meal a day, whether you need it or not. ;-)
