It is marketed as a diet. however its based on the idea that if you have a reduced calorie intake you'll live longer. However: a) its yet to be proved in humans (worms, flies and lemurs, yes.)[1] b) to get the benefit we're talking about ~1800 calories a day. Having accidental done something like that for almost a year, I cannot stress how terrible your quality of life is.
