Fad diets

thumb|A glass of water on an empty plateFasting is the act of refraining from eating, and sometimes drinking. However, from a purely physiological context, "fasting" may refer to the metabolic status of a person who has not eaten overnight (before "breakfast"), or to the metabolic state achieved after complete digestion and absorption of a meal. Metabolic changes in the fasting state begin after absorption of a meal (typically 3–5 hours after eating).

Superfood is a marketing term for food claimed to confer health benefits resulting from an exceptional nutrient density. The term is not commonly used by experts, dietitians and nutrition scientists, most of whom dispute that particular foods have the health benefits claimed by their advocates. Even without scientific evidence of exceptional nutrient content, many new, exotic, and foreign fruits or ancient grains are marketed under the term – or superfruit or supergrain respectively – after being introduced or re-introduced to Western markets.
