February 17, 2012 The Food and Drug Administration will take a second look at a weight-loss drug it rejected in 2010.

A high-protein diet, without a reduction in calories, isn't a recipe for weight-loss success.
January 4, 2012 People on low-protein diets pack on more fat compared to people who eat normal amounts of protein, a new study concludes. This is bad for health, even if the low-protein folks don't put on as many pounds. Eating more protein may make it easier to keep weight off.
December 28, 2011 Pigging out for even a day causes inflammation in the brains of lab rats, and scientists think this might help explain why it's so hard for people to lose weight. If eating too much inflames human brains, too, then scientists might be able to come up with new ideas for taming obesity.

November 4, 2011 The Federal Trade Commission said it has reached a settlement with David J. Romeo and two companies he controlled that bans them from "making any weight-loss claims while marketing foods, drugs, and dietary supplements."
