Dr. Oz reveals health lies and Chris Powell's carb cycling weight loss diet

Dr. Mehmet Oz examined common health lies and discussed Chris Powell's carb cycling weight loss diet on Aug. 18 episode of the Dr. Oz Show.

The first health lie Dr. Oz debunked is that most of your body heat escapes from your head. This is not true, contrary to what we've been told for decades. This myth can be traced to a U.S. army survival manual from 1970 which wrongly stated that "40 to 45 percent of body heat" is lost from the head.

Another health lie is that drinking alcohol warms you up. If anything, consuming alcohol has the opposite effect. Alcohol causes you to sweat, but it cools on your skin, causing your core body temperature to drop.

One health cliché that did stand up to scientific scrutiny concerned gargling. Dr. Oz said gargling with cold water does eliminate hiccups because cold water shocks and confuses the nerves.

Carb Cycling Boosts Metabolism and Weight Loss

On a separate segment of the show, Dr. Oz's guest was "Extreme Weight Loss" star Chris Powell, who said the best way to burn body fat and promote weight loss is to build lean muscle mass.

Powell, author of Choose to Lose: The 7-Day Carb Cycle Solution, said the more muscle mass you have, the higher your metabolism is all day long, so you lose weight and burn fat even when you're sleeping. Chris said resistance-training is the best way to boost fat-burning and stimulate lean-muscle growth.

Chris told Dr. Oz you can boost your metabolism and increase lean muscle production with a simple five-minute workout. He suggested doing 10 reps of jumping jacks that work your glutes, calves, shoulders and abs, or doing stomach crunches while sitting in a chair.

Powell also advocates a carb cycling diet, or alternating between days of high-carb intake and low carb intake, to keep your body guessing and your metabolism fired up. On Chris' carb cycling diet plan, you can eat 1,200 calories on a low carb day, 1,500 calories on a high-carb day, and up to 2,400 calories on a cheat day.

Powell said cycling carbs is better than an extreme low-carb diet, which he says does help you lose weight, but may backfire in the long haul if you're not careful, resulting in stalled weight loss or rebound weight gain.
