The Zone Diet Review

The Zone Diet - A closer look at the science behind the claims.

The purported health benefits of low-carbohydrate diets have been advocated intermittently over the last century and have enjoyed increasing popularity over the last decade.

Although most revolve around the emphatic theme that carbohydrates are to blame for many chronic diseases, their specific ideologies are more variable and in some cases quite sophisticated.

The Zone Diet phenomenon represents a new generation of modern low carbohydrate food fad with sales placing it among the most popular diet books in recent history. The Zone is a 40 percent carbohydrate, 30 percent protein and 30 percent fat eating plan that advocates only sparing use of grains and starches.

The precise 0.75 protein to carbohydrate ratio required with each Zone Diet meal is promoted to reduce the insulin to glucagon ratio, which purportedly affects eicosanoid metabolism and ultimately produces a cascade of biological events leading to a reduction in chronic disease risk, enhanced immunity, maximal physical and mental performance, increased longevity and permanent weight loss.

There is presently little scientific support for the connections made between diet, endocrinology and eicosanoid metabolism, made in the Zone Diet. In fact, a review of the literature suggests that there are scientific contradictions in the Zone Diet hypothesis that cast unquestionable doubt on its potential efficacy.
