Zone diet, unlike other diets that limit themselves to accounting for calories with the aim of simply losing weight, is that it is proposed as a change in lifestyle. Starting from important assumptions, we have come to the conclusion that food does not only provide calories, nutrients, vitamins and mineral salts, but it modulates the production of hormones. In fact, through nutrition we have the possibility of favoring certain hormones, modulating their effects on our organism.

Another important attention must be paid to blood sugar, in fact, with the zone diet we avoid large fluctuations which often lead to negative repercussions on our health. Reducing blood sugar fluctuations can be achieved by eating often, five or six times a day in addition to respecting the basic rule of the zone diet, the ratio at each meal 40-30-30. These numbers mean that the calorie intake for each meal will have to come from 40% from carbohydrates (preferably slowly absorbed, such as fruits and vegetables), for the 30% to protein ( better if from white meat or fish, even better if from soy or other legumes that do not contain animal fats) and for the 30% from predominantly vegetable fats ( in particular olive oil). Because carbohydrates, like proteins, they produce 4 kilocalories per gram, while fats produce them 9, in order to combine the various nutrients in the right proportions it will be necessary to consume 9 grams of carbohydrates along with 7 grams of protein e 3 grams of fat, to maintain the approximate proportions of 40-30-30.

dieta a zona ideata dal Dott. Barry Sears, è un indicazione di un corretto modo di mangiare, distribuendo i nutrienti nelle proporzioni adeguate. Per questo la dieta a zona a differenza delle altre diete non finisce mai. Non si deve mai dimenticare che il giusto completamento di questa dieta è una costante attività fisica. Infatti fina dall’antichità, già il grande medico Ippocrate (460-377 a.C.) diceva: “Se fossimo in grado di fornire a ciascuno la giusta dose di nutrimento ed esercizio fisico, né in difetto né in eccesso, avremmo trovato la strada per la salute”.
