The WebMD site has a nice little article on crash diets, called “The Worst Diets Ever: Diets That Don’t Work.”  While it doesn’t call out very many diets by name, it provides a good set of guidelines on how to evaluate a diet program. 

What does a bad diet look like?  The author, Kathleen Zelman, offers 5 criteria to ID which ones to avoid:

  • Diets that focus on only a few foods or food groups
  • “Detox” diets
  • Diets with “Miracle” foods or ingredients
  • Fasting and very low calorie diets
  • Diets that sound too good to be true

Read the whole thing: it’s a good reality check.
