Get Faster
Flab's a drag. Literally. For every pound of fat you lose, you run up to 4 seconds faster per mile; with 10 gone, that's up to 40 seconds off your mile time, says Paul Vanderburgh, Ed.D., an exercise physiologist at the University of Dayton. "Your body won't have to work as hard to go forward."
Improve Your Mood

Earn More Dough
Women with excess pounds make nearly $10,000 less per year than their average-weight coworkers. Possibly they are less assertive. (It takes cojones to ask for a raise!) Slim down and you may up your take-charge attitude and your take-home pay.
Sex Up Your Sex Life
"The biggest benefits in the bedroom come from weight loss and regular exercise. Both put women in touch with their bodies in a positive way, which increases sex drive," says Ronette Kolotkin, Ph.D., a consulting professor at Duke University School of Medicine. "Plus, there's no lingerie sexier than confidence-and a small loss can take you there."

Stay Off the Sidelines
Downsize yourself and your risk of injury diminishes, too. Every pound of body weight translates to about 4 pounds of force on your ankles, knees and hips when you're walking, so 10 extra pounds on your frame means 40 more pounds of pressure on your joints. Trim down slightly and your joints will suffer less wear and tear.
"After dropping 10 pounds, I bought my first pair of skinny jeans," says Shelley Senai, 27. "Before, I didn't feel comfortable in anything fitted. Now I love the look."
