This amazing announcement comes from none other than the American Heart Association (AHA) published in the Jan. 17, 2006, issue of its journal Circulation.

Cardiomyopathy, defined as a weakening of the heart muscle or change in structure...

Bob Krause hates Thanksgiving, and not because of that all forced family time. Krause, 63, calls himself a picky eater -- one who won't eat anything that's served at a traditional Thanksgiving dinner, or any other dinner, for that matter.

The fascination with low-carb versus low-fat diet continues; the latest news comes from a study in the Annals of Internal Medicine released today that found that people on both diets lost about the same amount of weight over two years.

"Most ethnic differences in cardiovascular risk are really due...
