Zone Diet: General Information

Diet Author The Zone Diet, created by Dr. Barry Sears, started its way to Olympus of nutritional approaches and weight-loss programs in 1995. At that time Dr. Sears published his first book to introduce the Zone Diet, which was to become a dietary road map for every obese or overweight person, willing to lose weight permanently, reset his genetic code, prevent diseases and achieve maximum physical performance.

Dr. Barry Sears is a former medical researcher, who worked at the Boston University School of Medicine and the Massachusetts Institute of Technology, studying lipids and their inflammatory influence on the development of certain diseases.

Nowadays, having brought the Zone to the diets arena, published 11 diet books and founded the Inflammation Research Foundation, called to develop innovative dietary approaches, Dr. Barry Sears is considered to be one of the most well-known nutritional gurus in America.

Diet Categorization Of course, every diet author tries to introduce his nutritional approach as a unique, brand-new and one-of-a-kind weight-loss and health-improving program. The Zone is said to be rather a life-long food management system, ensuring permanent fat loss, than just a diet.

However, any diet (including the Zone) is nothing but a remix of the traditional combination of three diet components: carbohydrates, fats and proteins, spiced with alluring, but sometimes scientifically unproven suggestions.

According to the traditional approach to nutrition, a healthy diet should contain 50-60 % of calories, derived from carbohydrates, 30 % - from fats and 10-20% - from protein. The Zone promotes decreasing the share of carbohydrates to 40% and increasing the share of proteins to 30%. Consequently, the Zone Diet is low-carbohydrate, high-protein eating plan.

Diet History The Zone belongs to the old-timers among weight-loss programs popular in the USA. The diet was created in 1990 by Dr. Barry Sears and first introduced in 1995 with the book of the same name. The popularity of the Zone was reinforced with the appearance of the next books, authored by Dr. Sears: Zone Food Blocks (1998), The Age-Free Zone, The Omega Rx Zone (2003) and The Anti-Inflammation Zone (2005).

Diet motto The whole idea of the Zone Diet is based on the suggestion that it is the excess of insulin, a sugar-regulating hormone, that makes people fat and keeps them fat lifelong. The Zone itself is not a magic place, but a physiological state, where the level of insulin is maintained at the optimal level (neither too high, nor too low). To enter the Zone, the diet promotes so-called 40:30:30 ratio, which means that ideal meal should provide 40% of calories from carbs, 30 % - from fats and 30 % - from proteins.

Diet Duration Following the rules of the Zone Diet has neither time-limits nor specific phases or stages. The Zone is a life-long eating strategy, called to keep the insulin level under control by means of a diet.

What improvements are declared by the diet? Up to 10 pounds of weight loss in five weeks, increased energy and general health improvements are among the major perspectives, promised by the Zone Diet. Besides, due to balancing the insulin level, the Zone Diet is said to decrease the cardiovascular risks and improve physical and mental performance.
