Of course their focus on vegetarianism and temperance (no drugs/alcohol/smoking) has a LOT to do with it, but I thought it was interesting that an equally important factor was eating small amounts of nuts several times a week. I CAN HANDLE THAT!
Also interesting, they treat gluttony on par with other sins, here in the US it seems many denominations are not that concerned with gluttony sin-wise, if you've ever been to a church pot luck you know what I'm talking about! In Adventist culture it is seen as distasteful to be pounding food in public, in my ex church, somebody was always pushing another piece of lasagna or brownie or donut or something, it seemed every event there was centered on food! Even after mass they always had people selling donuts and bagels in the parking lot.

Anyway, interesting article for dieters of all beliefs. I have no interest in being in that religion (or any religion!) I sure would like to pick up a few of their good habits!
