You could, but will it work? I went for one of the fad diets and it did not work for me. Considering there million quick weight loss diets out there I might have chosen the wrong one, but still I remain skeptical. The only way to find out whether a diet works or not is to try it out! A friend of mine once tried the South Beach diet and she said that she lost some weight. So you can opt for this and see if it works. But when you reach my age, losing weight becomes very difficult and you have to struggle with it for many months before you lose a little bit of weight.
