According to Michael F. Roizen, MD and Mehmet C. Oz, MD.
Building muscle is one component of exercise, but cardiovascular training and increasing your flexibility are also part of your fitness plan. Together, the three components of exercise will have numerous effects on your body:
-Exercise increases your metabolism so that you burn energy at a higher rate than if you didn't exercise, and it reduces your appetite by turning on your sympathetic nervous system, which activates your fight-or-flight response. Take a quick walk or jog when you feel the first twinge of hunger. Your hunger is gone when you return.
-Exercise will help you lose the extra weight that's stressing your joints. By dropping weight, you'll feel less pain in your knees, hips, ankles, and back. And that will put you into a positive cycle of behavior, so that you'll have the desire to exercise more.
-Exercise stimulates the release of endorphins, which stimulate the pleasure centers in the brain. When they're stimulated, they give you a sense of control, which is associated with a decreased need to eat out of control.
-Exercise helps decrease depression and increases positive attitude, so you make other positive choices and don't have to use food as your medication.
-Exercise keeps your blood vessels open and clog-free, thus decreasing your risk of obesity-related morbidities like high blood pressure, elevated cholesterol, memory problems, and heart attacks.
FACT-As you increase the intensity of your exercise, the typical body utilizes a higher percentage of carbohydrate-fueled energy rather than fat-fueled energy. Some incorrectly interpret this to mean that as you increase exercise intensity, you are no longer burning fat, but burning only carbohydrates. Since the total number of calories burned during higher-intensity exercise is larger than the number of calories burned at lower intensities (even though a slightly higher percentage may come from carbohydrates than fats), you are almost always using (burning) more total fat than if you worked at a lower intensity.
