Observations of older men and women who maintain an active lifestyle suggest that 'normal' patterns of weight gain in adulthood can be attenuated. For both young and middle-aged males and females that exercise regularly, the time spent in physical activity was inversely related to body fat levels. Surprisingly, no relationship was found between body fat and caloric intake, suggesting that the greater levels of body fat observed, especially among middle-aged individuals was more a function of LESS VIGOROUS EXERCISE, not greater food intake.
Exercise and diet play an important role in weight management. Studies have shown that the greatest weight loss resulted with a program which combined diet and exercise.
Many of the benefits of regular exercise come about because of an improved aerobic capacity. That is, the more fit you are, the easier your body distributes oxygen to your working skeletal muscle. This efficiency comes about as a result of improvements in your lungs, heart and circulatory system. In fact, those who exercise regularly experience more energy throughout the day and are better prepared to handle stress.
