"Researchers knew that just about anyone who deliberately loses weight — even if they start at a normal weight or even underweight — will have a slower metabolism when the diet ends."
"Some scientists say weight maintenance has to be treated as an issue separate from weight loss. Only when that challenge is solved, they say, can progress truly be made against obesity."

This is a terrifying read about how the body slows down when you deliberately lose weight, and the true challenge of maintaining weight loss. I'm looking forward to the weight maintenance games to be out of beta and available for participation. I would love to host one and share what I know about exercise physiology and how to keep the metabolism burning hot.
