Here we go again! More hope that there's a way to eat less and lose weight without feeling hungry: research shows that a fullness hormone just might do that trick.

Symlin, which is a synthetic version of the natural hormone 'amlin' and is often used to treat diabetes, was recently studied to see how it affected the appetites of obese men and postmenopausal women. Compared to a placebo, the people taking Symlin injections prior to meals ate significantly fewer calories daily over a six week period and ended up losing quite a bit more weight -- all without feeling hungry.

No word just yet on how (or if) this will make it to the general population (I'm thinking injections before every meal are a little painful!), but it seems promising. But is it too promising? Sounds a little "too good to be true," and that's always a red flag.
