Exercise and Weight Loss
Regular exercise is an important part of effective weight loss. It helps to control your weight by using excess calories that otherwise would be stored as fat. Physical activity also helps prevent many diseases and improve your overall health.
Your weight is determined by the number of calories you eat each day minus what your body uses. Everything you eat contains calories, and everything you do uses calories, including sleeping, breathing, and digesting food. Any physical activity in addition to what you normally do will burn those extra calories.
Delia A. Hammock, M.S., R.D. The hottest new items in supermarkets are making amazing claims. But do they really work — and are they safe? GHRI investigates. It can be hard to tell if you're at the grocery store or the pharmacy these days. More and more food products tout medical benefits that go way beyond basic nutrition. Called "functional foods," they contain specific ingredients that have been added to promote good health. But do they? You won't always be able...

Balancing the number of calories you expend through exercise and physical activity with the calories you eat will help you achieve your desired weight. The key to successful weight loss and improved overall health is making physical activity a part of your daily routine.
The Health Benefits of Exercise
Research consistently shows that regular exercise, combined with healthy eating, is the most efficient and healthful way to control your weight.
In addition to helping to control weight, research shows that regular physical activity can reduce your risk for several diseases and conditions and improve your overall quality of life. Regular exercise can help prevent:
- Heart disease and stroke. Daily physical activity can help prevent heart disease and stroke by strengthening your heart muscle, lowering your blood pressure, raising your HDL ("good" cholesterol), and lowering LDL cholesterol ("bad" cholesterol), improving blood flow, and increasing your heart's working capacity.
- High blood pressure. Regular exercise reduces blood pressure in people with high blood pressure (hypertension).
- Diabetes. By reducing body fat, physical activity can help to prevent and control type 2 diabetes.
- Back pain. By increasing muscle strength and endurance and improving flexibility and posture, regular exercise can prevent back pain.
- Osteoporosis. Regular weight-bearing exercise promotes bone formation and may prevent many forms of bone loss associated with aging.
Regular physical activity can also improve mood and the way you feel about yourself. Exercise is likely to reduce depression and anxiety and help you to better manage stress.
Types of Exercise
It does not matter what type of physical activity you perform -- sports, planned exercise, household chores, yard work, or work-related tasks -- all are beneficial.
Over the past few years, exercise advertisements have targeted simplified exercise routines for weight loss and maintenance. Some exercise advertisements sell the belief that one machine will work your entire body and give you the results you need. However, many of these machines may only be good for one type of conditioning, such as cardiovascular; these machines also have limitations to the type of exercise you can do and they are not good for everyone. To determine the best type of exercise program for you, talk to your doctor and a certified athletic trainer.
