The two major players in a weight- loss program are diet and exercise. Many people tend to focus on diet when they're trying to lose weight; however being physically active is also an essential part of a weight-loss program. Research shows that the results are poor for long-term weight loss through diets. Normally, only about 5% of dieters can keep the weight they lost, and weight cycling is very common. Usually a part of weight loss is regained within one year and almost all is regained in a period of three to five years. Considering these data we can conclude that the combination of exercise and diet is more effective in weight loss.
