9 Unhealthy Fad Diets You Should Never Try (2 of 5)

Cotton Ball Diet

The cotton ball diet may be one of the most dangerous fads around. This diet entails eating cotton balls that have been soaked in juice or smoothies. Not only does it deprive you of basically all needed nutrients, but stuffing your body with cotton balls can cause seriously dangerous blockages in your digestive tract.

Cookie Diet

The cookie diet is all about skipping meals and eating cookies all day. But not just any cookie — you are required to eat special cookies by Dr. Sanford Siegal, and you eat them every two hours. But this will only give you about 1200 calories a day, max — which is way too low.
