Both the Google and Diets in Review list do have their share of drastic, out-there fads. Beside raspberry ketones (the No. 3 Google diet search) Googlers were interested in the K-E Diet (short for ketogenic enteral nutrition), which involves inserting a plastic hose through the nose, down through the esophagus and into the stomach, making it harder to eat.

But even though eight supplements, a baby food diet and several supermodel-sanctioned cleanses made it into this year's top 25, Koskie said she is heartened to see that most of the weight loss methods, especially near the top of the site's list, are relatively sane and sensible.
"I think things like Weight Watchers and Jillian Michaels are there year after year because people can stick with them and they actually get results without starving themselves or making themselves crazy," she said.
