Real Weight Loss Happens Slowly, or You'll Regain the Weight
The Biggest Loser is the newest TV survivor show. For nine weeks, a dozen people are vying for the biggest weight loss -- huffing, puffing, starving, sweating, swearing. And yes, they're losing weight.
The two teams' strategies: The low-key Blue Team has group therapy, eats six small meals daily, and exercises some. Just the opposite for the Red Team: They're exercising round-the-clock, sleeping little, eating little -- prodded by their drill-sergeant style trainer.
Glass-fronted "temptation refrigerators," stocked with pizza, beer, cakes, pies, are dangerously close by. Can these 12 people resist their biggest temptations for $250,000? Yes, they can.
First week, the Red Team won, losing 74 pounds total -- with one guy losing 20 pounds. Dana was voted off the Blue Team; her loss was only five pounds. (However, at 167 pounds, Dana started out less overweight than most contestants. Dana lost another 15 pounds later.)
It's reality TV. But realistic? Are aggressive weight loss tactics a good or bad thing?
Weight Loss Experts Weigh In
"I don't believe in such a thing as jump-starting a weight loss plan, not even for motivational reasons," says Jody Wilkinson, MD, director of the Cooper Institute Center for Weight Management.
"There are some people who respond very well to that approach, but only a very small minority," he tells WebMD. "For people who don't have much weight to lose -- who have some motivation and readiness -- an aggressive approach can work. But that's the exception rather than the rule."
Weight loss is a three- to five-year process, says Wilkinson. "For lifestyle to change and physiology of the body to change, it truly is a long-term process. We recommend losing 1% of current body weight every week. Otherwise, body chemistry gets out of disturbance, and you lose only water weight and lean [muscle] tissue, which causes your metabolism to drop, making it even harder to lose weight."
The human body is really not designed to lose weight, Wilkinson explains. "Storing energy, gaining weight, is the body's survival mechanism. In primitive times, people who could do that were the ones who survived. Anytime the body senses it's losing weight -- regardless of how overweight you are -- it doesn't want to lose weight and triggers all sorts of responses that resist weight loss."
