Diet + Exercise = success!

"Yes, you can lose weight with diet alone, but exercise is an important component. Without it, only a portion of your weight loss is from fat -- you're also stripping away muscle and bone density. Since working out stimulates growth of those metabolic tissues, losing weight through exercise means you're burning mostly fat. Data show that to lose weight with exercise and keep it off, you don't need to run marathons. And, of course, beyond burning fat, people shouldn't forget that exercise can have other impressive health perks, like improving the quality of your sleep, lowering your cholesterol and reducing your stress level!"
