Are there any fad diets that would be best to avoid?

Fad diets have been around for hundreds of years. The truth is fad diets don’t work to help you keep the weight off long-term. Adopting a healthful eating pattern that you can maintain for life is the goal. What you consume needs to balance with your activity level to maintain a healthy body weight. According to the American Academy of Nutrition and Dietetics, you may be able to identify a fad diet if it:
•Sounds too good to be true, it probably is. Such as: “Lose 15 lbs in 7 days!” or “lose weight without changing a thing!”
•Recommends using a single food on a very consistent basis.
•Promises quick and easy weight loss with no effort.
•Eliminates an entire food group such as fruits, dairy, fats, or grains.
•Guarantees an outcome in a specified time period.
•Bases evidence for effectiveness only on the quotes of other dieters
