Beverly Hills Diet
A fad diet of dubious efficacy, based on the premise that the body needs enzymes found in certain foods, in particular in fruits, to digest properly. Per author Judy Mazel (1943-2007, The Hollywood Diet, Macmillan, 1979), foods that aren’t digested, turn into fat.
The diet has been criticised for its lack of adherence to sound nutritional principles. Criticisms include the questionable admonition that fruits* be consumed on separate days–e.g., papaya on one day, pineapple on the next, and so on; in addition to its low amount of protein (only 6% of the caloric content is protein), the Beverly Hills diet supplies no vitamin B12, one-third the recommended daily allowances (RDAs) for calcium, and one-half or less of 5 essential nutrients. That Mazel–a frustrated wannabe actor–had no formal training in either medicine or nutrition when she invented The Beverly Hills Diet and the fact that the Diet is founded on no known scientific principle has not prevented millions from buying the book or buying into the quackery. Mazel died of peripheral vascular disease at age 63, which some regarded as proof of the (in)efficacy of her Diet.
