Use fat to burn fat.
Trying yet again to lose those last 10 pounds? We hear you. In fact, 50 percent of women say that within six months they gain back any weight they've managed to ditch. And more than a quarter have dieted so many times they've lost track of the number. Well, get ready to stop the endless yo-yoing: Science has finally come up with simple, groundbreaking solutions for lasting weight loss. We checked in with the top experts in the field and scoured the latest research to bring you the skinny on everything you need to reach your slim-down goals and stay there.
Make your fat burn fat.
Seriously: Your flab 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, MD, PhD, 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 gobble up as much as 20 percent of your body's calories.
Exercise is one of the best ways to get your brown fat in gear. In a study, scientists at Harvard's Dana-Farber Cancer Institute discovered that working out releases a hormone called irisin, which converts white fat to brown. Exercise for a half hour at least five days a week to turn up the burn.
some vitamin D.
Taking this vitamin daily may help you drop pounds. A study at the University of Minnesota found that people who started a weight-loss program with higher levels of D lost more than those who weren't getting enough of the nutrient. Other research suggested that vitamin D appears to boost the effectiveness of leptin, a hormone that signalsthe brain that you're full. Because it's difficult to get D from food, Shalamar Sibley, MD, an assistant professor of medicine at the university, says you may need to take a vitamin D3 supplement. Many experts now recommend 1,000 international units every day.
Chew on this.
Most of us eat quickly, chewing each bite just a few times, which means we consume more food than we realize.Slow down and you'll slim down: In a recent study, people who chewed each bite 40 times ate almost 12 percent less than those who chewed just 15 times. When we chew longer, our bodies produce less ghrelin, a hormone thatboosts appetite, and more of the peptide hormones that are believed to curb hunger. "Chewing seems to stimulate the gut to make appetite-suppressing peptide hormones," Dr. Cypess explains. Plus, the more you chew, the more thoroughly you break down food, which may release nutrients into your blood faster and give your brain time to register that you're full. From now on, focus on eating slowly at every meal. Put down your fork between bites and work your way up to 40 chews per mouthful of food.
Sip green tea.
This healthy brew acts like a diet drug in a mug, but without the negative side effects. A review of studies concluded that regularly sipping green tea can help you drop pounds. This weight loss is the result of EGCG, a compound known to reduce fat absorption, according to new research from Penn State. But that's not all this magic drink does: As it's reducing fat absorption, "green tea also increases the amount of fat that your body eliminates," explains study author Joshua D. Lambert, PhD, an assistant professor of food science at the university. So think about trading your usual afternoon java for green tea instead. Experts say that drinking three to five cups of the regular or decaf variety every day may help you lose weight.
