The Rosedale diet is a low-carbohydrate fad diet based on the ideas of Ron Rosedale about how leptin affects the human body. The diet is marketed with questionable claims about how it can treat a large number of human health conditions.[1]
The Rosedale diet is not based on sound science, and there is no evidence it is safe or effective.[1]
The Rosedale diet was devised by physician Ron Rosedale.[1]
The diet falls into two parts, both of which have lists of restricted and permitted foods. A number of health supplements are recommended, as are 16 unconventional annual health checks.[1] Generally, the diet severely restricts carbohydrate intake.[2]
Harriet Hall has written that the book describing the diet is a "puerile effort" in comparison to Gary Taube's book Good Calories, Bad Calories which at least attempted to have a scientific basis.[1]
The diet has been recommended by Joseph Mercola. Hall writes that "neither Mercola nor Rosedale can be recommended to anyone who is interested in science-based medicine".[1]
