Load up on low-fat dairy: Women who consumed milk, yogurt, and cheese three to four times a day lost 70 percent more body fat than women who didn't eat dairy in a study published in the January 2003 American Society for Nutritional Sciences Journal of Nutrition. The reason: Calcium, along with other substances in dairy, actually revs up your metabolism, telling your body to burn excess fat faster, according to study author Michael Zemel, Ph.D., director of the Nutrition Institute at the University of Tennessee in Knoxville. And no, fortified o.j. won't do the trick. The best results come from dairy products instead of from other calcium-rich foods (like broccoli), calcium-fortified products (such as orange juice) or supplements. Women reap the largest fat-burning benefit when they consume three servings of dairy and 1,200 milligrams of calcium a day, Zemel's research shows.
Even when you’re at rest, your body is constantly burning calories. In fact, 75 percent of the calories that you burn each day are being used up just keeping you alive. “Resting metabolic rate” is much higher in people with more muscle, because every pound of muscle uses about 6 calories a day just to sustain itself. If you can pack on just five pounds of muscle and sustain it, you’ll burn the caloric equivalent of three pounds of fat over the course of a year.
As the endocrine system controls the rate and direction of metabolism, what you consume and your level of physical activity will overall influence the speed of your metabolism and how much you weight you gain. The belief that your metabolism is to blame for increased fat is not correct. Eating more calories than you can burn is the primary cause. The best way to control how many calories you burn is through your level of physical activity, according to the Mayo Clinic. What appears to be a faster metabolism in others is more often a more active lifestyle, that leads to weight loss or maintaining a steady weight.
