Physical activity is the next most important way of burning energy. When the energy taken in is not entirely spent by the body, it accumulates in the form of fat. Research shows that weight loss is greater with dieting alone than with exercise alone. Physical activity may not show as much progress as dieting on the bathroom scale, but it often works in other ways. Successful weight loss is measured not only in pounds lost but also in long-term results.
Physical activity is clearly superior in long-term maintenance of weight loss.
Most success stories include regular exercise. As with dieting, however, the effect of physical activity is rapidly reversed as soon as physical activity is discontinued. To make sure that physical activity becomes a part of your lifestyle, select an activity that appeals to you. If you choose a less demanding, more comfortable activity, increase the time you spend at it. Do one hour of moderate walking instead of a half hour of brisk walking, for example.
