they are primarily consuming liquids and little fat. In addition, any diet that restricts calories to 1,000 per day is likely to result in weight loss. Like many short weight-loss plans, however, the weight often comes back quickly.
Even though the grapefruit diet seems to help some people lose weight, health experts caution that the diet is actually unhealthy. Most do not recommend it, for two main reasons. First, the body needs a larger variety of vegetables, fruits, carbohydrates, and proteins to stay healthy. Second, because the diet only lasts twelve days, it does not teach useful eating habits that people can use in the future. It is a quick fix, but successful dieting requires time, effort, and regular exercise. Enjoy grapefruit as part of your diet, experts say, but don’t think it is the magic answer to losing weight.
