Regular exercise is a very important factor in healthy living. Not only can exercise help you maintain a healthy weight, it also gives your energy level a boost. Most adults require at least 30 minutes of moderate physical activity at least five days per week.

The key to weight control is keeping energy intake (food) and energy output (physical activity) in balance. When you consume only as many calories as your body needs, your weight will usually remain constant. If you take in more calories than your body needs, you will put on excess fat. If you expend more energy than you take in you will burn excess fat.

Exercise plays an important role in weight control by increasing energy output, calling on stored calories for extra fuel. Recent studies show that not only does exercise increase metabolism during a workout, but it causes your metabolism to stay increased for a period of time after exercising, allowing you to burn more calories.

On the other hand, lack of physical activity causes muscles to get soft, and if food intake is not decreased, added body weight is almost always fat. Once-active people, who continue to eat as they always have after settling into sedentary lifestyles, tend to suffer from “creeping obesity.”

Having said that, it is good to know that the amount of exercise that would make a difference in your weight depends on the amount and type of activity, and on how much you eat. Aerobic exercise burns body fat. A medium-sized adult would have to walk more than 30 miles to burn up 3,500 calories, the equivalent of one pound of fat. Although that may seem like a lot, you don’t have to walk the 30 miles all at once. Walking a mile a day for 30 days will achieve the same result, providing you don’t increase your food intake to negate the effects of walking.

If you consume 100 calories a day more than your body needs, you will gain approximately 10 pounds in a year. You could take that weight off, or keep it off, by doing 30 minutes of moderate exercise daily. . Stretching and weight training can also strengthen your body and improve your fitness level but the key is to find the right exercise for you. If it is fun, you are more likely to stay motivated.

There are 1,440 minutes in every day. So schedule 30 of them for physical activity!
