I've noticed that, too. I suppose that some of it is cultural; it's more acceptable socially for men to be overweight than women. Also, I think often the reasons vary why men become overweight vs. women. Men (not all, of course) tend not to be emotional eaters; we like *big* quantities, because we're big strong men. We've worked hard for that trip to Outback, and we deserve their biggest offering. A full plate of spaghetti? Yes, please, with seconds. A 12-pack of beer in the summer in a day? No problem. And years of this made us who we are.
It's a quiet killer, though. In 2009, I took a 2-week trip to China to visit friends. I was lucky to fit in a single seat in the airplane. They were amazed at how much I ate, and the choices I made. There is a lot of street food in China; you can get corn on the cob, steamed dumplings, fried dumplings, scallion pancakes, and a host of other things like fresh fruits and vegetables. I consistently chose things that were fried, or were bad for me (like eating at KFC there), despite my friend's advice. You can see pictures in my profile of what I looked like then. None of them ate the way I did, and I didn't see a lot of overweight Chinese people.
Those of us who are sleeved, or pursuing the sleeve, have pulled back from the edge of the funnel. This really is the last station of the diet train; we get off here.
Good luck to everyone!
