Question

The major drawback of most fad diets is:
a. they promote false information about weight loss.
b. they do not create lifestyle changes to support long-term weight control.
c. they create false hopes among those who try them.
d. they usually require the purchase of dietary supplements.

Answer 1

All of these can be true of fad diets but A is especially true. You need a balance of foods in order to be healthy and many fad diets don't support this. They teach dieters to eat a lot of a few types of food which creates an unhealthy idea of how to lose weight.
