ELIXIR OF LOG LIFE
The “zone diet” is above all a lifestyle that derives from the dietary plans of US athletes. It consists of a substantial calorie restriction based on the strong reduction of carbohydrate consumption. The intracellular reactions caused by the reduction in the amount of calories absorbed produce a significant improvement in health conditions. So as to make this diet be considered a real elixir of long life. Then, at the basis of this diet is the calculation of the “real” energy needs of each individual, that is, compared to the lifestyle. For example, it is said that an individual should ingest 1800 – 1900 kcal / day. But who is sedentary or has a slowed metabolism should introduce less).
The thermal basis of this diet was formulated by the American physician and biochemist Barry Sears. So it is based on the functionality of special hormones called eicosanoids. They are produced by the cells of our body but there are “goodproduction of the “good” ones and hinder the production of the “bad” ones. At the basis of this control is the regulation of insulin levels. So it is essential to balance the quantity and quality of ingested foods very well. Then it is important to establish the correct need for proteins, carbohydrates and fats. In particular that depend on individual characteristics such as lean body mass and physical activity.
Dr. Sears calculated the energy sources for our body in this way: 40% carbohydrates, 30% proteins, 30% fats. With these proportions there would be good control of insulin levels with a not excessive entry of sugars into the cells. Therefore their reduced transformation into fats. Insulin control is also very important to prevent the main enemy of those who want to go on a diet, namely hunger attacks. They are an unstoppable and often compulsive need to ingest food, especially carbohydrates and sugars in particular. Pproduces uncontrollable hunger attacks because an increase in insulin levels triggers so-called “chemical hunger”. Cereals have an unbalanced nutrient content in favor of carbohydrates so they will inevitably raise blood sugar. He said that “zone diet” is above all a lifestyle. http://www.sears.com
PROTEINS AND INSULIN http://www.insulin.com
The validity of the zone diet consists in taking foods that are not very balanced towards carbohydrates. Anyway with a preference for proteins in order to stimulate little insulin and all the harmful effects that its increase produces. In theory, meals rich in meat, fish, eggs and poor in pasta or rice should be prepared. So all this represents a problem for those who are vegetarian or vegan or care about their health. So they do not want to exaggerate with protein sources of animal origin. Soy, in this case, represents the ideal solution. I’s because it is the only plant-based food in which the protein / carbohydrate ratio is clearly in favor of proteins. Therefore insulin will be little stimulated with great satisfaction of vegetarians who will be able to obtain these results without resorting to animal protein sources.
This healthy protein / carbohydrate ratio of the zone diet will also have a great anti-inflammatory function with a great benefit for body tissues. Then it is so thanks to the stimulation of the production of “good” eicosanoids. Another useful stimulus for our health generated by the zone diet is to increase the production of glucagon. In fact it is the hormone insulin antagonist. The reduction of insulin produces beneficial effects such as reduced fat accumulation and good blood glucose levels and general state of health. As well as fighting diabetes which can be congenital or even acquired due to an incorrect lifestyle. dr. Massimiliano Mangafà
