This 1980’s blockbuster encourages the "food combining" or separating certain foods, theoretically allowing the body to properly digest each food. A mixture of foods leads to "confused" enzymes, the author professes. During the initial 35-day diet plan, calories can range wildly based on the all-you-can eat principle for certain foods.

Benefits:
The only benefit seen with this strict and sometimes confusing food plan is its extremely low calorie intake—weight loss is virtually assured.

Disadvantages:
Science reveals that the digestive tract was designed to handle all sorts of different food mixtures. While fat can slow the digestive process, it does hinder the absorption of nutrients. The plan is extremely low in protein, vitamins and minerals and is likely to cause stomach distress as a result of large quantities of fruit.

The New Beverly Hills Diet was created by Judy Mazel.
