Zone Diet :: Basis for the Zone diet
The basis for the Zone diet, by Barry Sears, Ph.D. (a biochemist, neither a physician nor a dietitian), is that if a person eats the correct ratio of carbohydrate to protein to fat (40/30/30), s/he will improve his or her health, weight, and athletic performance, because certain hormones will be balanced and therefore in the preferred “zone.” The hormones he focuses on are insulin (necessary for glucose to enter our cells) and eicosanoids (hormone-like substances that regulate inflammation. Some eicosanoids are by-products of metabolism.).
