The key to weight control is to maintain food intake and energy expenditure (physical activity) in balance. In fact, when you eat only the calories your body needs, weight generally remains constant, but if you eat more calories than your body needs, this will represent an excess of fat and, conversely, if the person consumes more energy than you eat, burn excess fat.
Exercise plays an important role in weight control by increasing energy expenditure. Recent studies show that exercise not only increases metabolism during a workout, but does keep your metabolism elevated for a period of time after exercise, allowing a person to burn more calories.
The volume of exercise needed to make a difference in your weight depends on the amount and type of activity and how much you eat. Aerobic exercise burns body fat. A medium-sized adult person would have to walk more than 48 kilometers (30 miles) to burn 3,500 calories, the equivalent of a pound of fat, although this may seem too much, you have to walk the 48 miles all at once. Indeed, walk a mile (a mile) daily for 30 days will achieve the same results as long as the person does not increase food intake to negate the effects of this activity.
If you eat 100 calories a day more than the body needs, you will gain 10 pounds (4.50 kg) per year, but that weight can be eliminated or avoided by doing 30 minutes of moderate exercise daily. The combination of exercise and diet offers the most flexible and effective method of weight control. (more…)
