A macrobiotic diet is a fad diet based on ideas about types of food drawn from Zen Buddhism. The diet tries to balance the supposed yin and yang elements of food and cookware. Major principles of macrobiotic diets are to reduce animal products, eat locally grown foods that are in season, and consume meals in moderation.

A fad diet is a diet that is popular, generally only for a short time, similar to fads in fashion, without being a standard scientific dietary recommendation, and often making unreasonable claims for fast weight loss or health improvements; as such it is often considered a type of pseudoscientific diet. Fad diets are usually not supported by clinical research and their health recommendations are not peer-reviewed, thus they often make unsubstantiated statements about health and disease.
Fad diets are popular non-standard diets that often promise dramatic weight loss. However, they are usually not supported by scientific evidence, and they sometimes offer dangerous dietary advice.
Lord Byron tried all kinds of fad diets, and devised one, the "vinegar and water diet" in the 1820s.
The tapeworm diet involved dieters who would willfully ingest tapeworms to absorb food in the intestine.
