Fad Diet: The diet that promotes a restricted eating-plan or certain liquid foods lacking sufficient food value is termed as Fad Diet. The fad diets are very low in calories so they cause quite fast weight loss. However, quick weight loss may not be healthy and - in most cases - is not fat loss. It is actually water-loss which is quickly regained when the dieter resumes normal eating. The fad diets can cause weight cycling, so fad dieting is also dubbed as ‘Yo-Yo dieting’, which means a continuing pattern of gaining and losing weight. The fad diets are considered unhealthy. The common examples of Fad diets include the Cabbage Soup Diet and the Grapefruit Diet.
Good Weight Loss Diet: The diet that helps losing weight in a positive manner is a good Weight Loss Diet. It does not reduce the energy. A balanced low fat diet is considered as the best weight loss diet. A balanced low fat diet is high in healthy carbohydrates, low in fat and moderate in protein.
A good Weight Loss Diet should be rich in whole grains, fruits, and vegetables, which are specially recommended for weight control and preventing diseases such as cancer and heart disease.
