Seriously: Your fat can help you shed pounds. How? Just as there's more than one kind of fat in food, there's more than one type in your body. White fat is the bad stuff you want to zap. But a second kind, brown fat, actually torches calories. "Up to 80 percent of adults have brown fat deposits in their bodies," says Aaron M. Cypess, M.D., Ph.D., an assistant professor of medicine at the Joslin Diabetes Center and Harvard Medical School. This good fat is powerful because it's packed with mitochondria, the parts of cells that generate heat. When activated, as little as two ounces of brown fat can burn as much as 20 percent of your body's calories.
In this study, eating more protein helped overweight men preserve more lean mass when they lost weight. The men were put on a diet that gave them either 15% or 25% of energy from protein. But here’s a huge difference that you won’t see in the abstract: the low-protein group was vegetarian; the high-protein group got meat. (The study authors never explain why on earth they would do it like that).
This could be because the body increases insulin secretion in anticipation that sugar will appear in the blood. When this doesn’t happen, blood sugar drops and hunger increases. Whether this chain of events regularly takes place is somewhat unclear. Something odd happened when I tested Pepsi Max though, and there are well-designed studies showing increased insulin when using artificial sweeteners.
Lap band (gastric banding) surgery, also referred to as laparoscopic adjustable gastric banding (LAGB) is a surgical procedure in which an adjustable belt is placed around the upper portion of the stomach. Candidates for lap band surgery are generally individuals with a body mass index over 40 kg/m2, or are more than 45 kilograms over their ideal body weight. Side effects, risks, and complications from lap band surgery should be discussed with a surgeon or physician prior to the operation.
