“If you lose 10 percent of your body weight, the number of calories you burn during the day drops by 30 to 40 percent,
because a smaller body requires fewer calories and your muscles become more efficient,”
After each diet period, the researchers tested the folks’ metabolic rates?and found that the low-carb diet completely prevented the metabolic slowdown often seen after weight loss. “People on the burned an average of 325 more calories a day?about the same number you’d burn during a moderately vigorous workout?than those on the low-fat diet, and those on the low-glycemic diet burned 150 more calories than those on the low-fat diet,” he says.
Whole grains increase metabolism, may help promote weight loss
One theory for why that happens: Reducing processed carbs, and as a result insulin levels, allows fat cells to release calories back into the bloodstream, helping to readjust the body-weight set point naturally, speculates Dr. Ludwig. He posits that reducing carbs even moderately?with a focus on the quality of your carbs?would be beneficial for shedding weight as well.
