Maybe you've been struggling -- without success -- to get down to the size you were in high school or on your wedding day. But do you really need to go that low? The truth, experts say, is that you can weigh more than your ideal weight and still be healthy (not to mention happy).
If you're overweight, losing just 10% of your body weight is associated with a myriad of health benefits, including lowering blood pressure, blood cholesterol, and blood sugar, and reducing your risk for heart disease. Not only that, experts say, but this kind of weight loss is easier to attain and maintain, setting you up for success in the long run.
Your Weight "Set Point"
Just as your body temperature is programmed to stay around 98.6 degrees, your body weight is naturally regulated to stay within a range of 10%-20%, says Thomas Wadden, PhD, director of the Center for Weight and Eating Disorders at University of Pennsylvania Medical School. This weight range is known as the "set point."
A complex set of hormones, chemicals, and hunger signals help your body naturally maintain your weight within this range, says American Dietetic Association spokeswoman Dawn Jackson Blatner, RD.
