The Zone diet is a low carbohydrate diet developed by biochemist Barry Sears. It specifies balanced portions of carbohydrates and protein at every meal. It also makes it easier to follow.
One of the ideas on which diet is based on a sense of satiety will discourage overeating. Also, like other low-carb diets, the glycemic index is used to classify carbohydrates. Both ideas are meant to promote weight loss in calories and insulin release, thus supporting the maintenance of insulin sensitivity. The Zone proposes a narrow distribution in the ratio of proteins to carbohydrates, centered at 0.75, which is essential to the balance of the insulin to glucagon ratio, which is highly eicosanoid metabolism and ultimately produces a cascade of biological events. chronic disease risk, enhanced immunity, maximal physical and mental performance, increased longevity and permanent weight loss. ” The Zone Diet is a fad diet in the low-carbohydrate diet that was created by Barry Sears, a biochemist. The diet advocates eating a carbohydrate, with 3 meals and 2 snacks, and including eating proteins, carbohydrates – those with a lower glycemic index are considered more favorable, and fats (monounsaturated fats are considered healthier) in a caloric ratio of 30% -40% -30%. The hand is used as the mnemonic tool; five fingers for five times a day, with no more than five hours between meals. The size and thickness of the carbohydrates and one fist unfavorable carbohydrates. There is a more complex scheme of “Zone blocks” and “mini-blocks” that followers of the diet can use to determine the ratios of consumed macronutrients. Daily exercise is encouraged. The diet falls over the continuum between the USDA-recommended food pyramid which advocates eating grains, vegetables, and fruit and reducing fat, and the high-fat Atkins Diet.
Like other low-carb diets, the theories underlying the diet zone are unproven. As of 2013, there have been no cross-sectional or longitudinal studies examining the potential health of adopting a diet zone, which is closely related to this diet. When properly evaluated, theories and arguments of popular low-fat carbohydrate dietbooks like the Zone rely on poorly controlled, non-peer-reviewed studies, anecdotes and non-science rhetoric. “
