1000 calories

1000 calories – one of kinds of rigid diets for weight loss limiting daily receipt of calories in an organism till 1000.

It is a little about calories

Calories are units of energy value of food. Calories characterize its general nutrition value together with such indicators as content of proteins, fats and carbohydrates.

Calories provide with necessary energy various processes of life activity including physical, and mental work. Energy is required for course of each of a set of biochemical reactions in an organism.

The person has a basic minimum need for calories within a day. Their energy value has to provide course of all physiological processes in a condition of the maximum rest and slackness (so-called, standard metabolism).

The need for energy for standard metabolism at all people different also depends on age and the surface area of a body. The adult man on average for ensuring the main exchange processes needs 1700 kcal a day, to the woman – is 1,5 times less.

Except a metabolism and work of internals energy in an organism is spent for intellectual and physical activity. With food to us much more calories can arrive, than it is required on providing standard metabolism. And if they completely are not spent, then will be laid in store – in the form of a glycogen in a liver and fatty tissue, and it as is well-known, is fraught with emergence of extra kilos.

At obesity it is possible and it is necessary to limit receipt of calories in an organism, and then mechanisms of an expenditure of own fatty stocks turn on. It allows to fight against excess weight.

Options of a diet of 1000 calories

The principles of a diet of 1000 calories are developed and formulated by the dietitian Anna Belousova. More correct would be to call this diet of 1000 kcal as the caloric content of food is measured in kilocalories.

Restriction of power providing to 1000 calories a day – very rigid method of controlling with extra kilos. To sustain a diet of 1000 calories, the person has to have excellent health.

The diet of 1000 calories exists in two options. In one of them the use of any food, including fat, fried is allowed, sweet confectionery, but the amount of food on energy value should not exceed 1000 calories a day.

The second version of the menu on 1000 calories describes a diet for weight loss in more detail. So, it is necessary to include in it:

• 300 g of fresh fruit;
• 400 g of vegetables;
• 500 ml of milk;
• 160 g of low-fat meat;
• 40 g of rye bread;
• 1 egg;
• 30 g of cottage cheese or 15 g of cheese (at choice);
• 15 g of butter.

Such set will provide an organism only with a part of energy, and missing will be filled from fatty stocks.

The approximate menu on 1000 calories a day

Of course, it is very difficult to count the caloric content of any eaten food in house conditions. Therefore nutritionists suggest to use more exact second option of a diet and the ready menu on 1000 calories a day.

Breakfast:

• Glass of skim milk (200 ml);
• The light-boiled egg;
• Grapefruit (100 g);
• Piece of rye bread (20 g);
• Butter (10 g).

The second breakfast – one of the following drinks:

• Tea;
• Coffee;
• Vegetable broth.

• Green salad;
• Fresh fruit (100 g);

Responses and opinions of specialists on a diet of 1000 calories

Nutritionists respond is very contradictory about a diet of 1000 calories. On the one hand, it allows to get rid for quite short term of 1,5 – 10 kg of excess weight. But on the other hand – the food allowance on a diet of 1000 calories longs as it is limited not only on energy value and volume of food, but also for useful substances – proteins, food fibers, vitamins and minerals. Deficit of some of them can at once and is serious be reflected even in a healthy organism, and also cause an exacerbation of chronic diseases.

For example, if on a diet of 1000 calories with food enough salts of magnesium and potassium ceases to arrive, then difficulties in cardiac performance will begin that is shown by disturbances of a rhythm of cordial reductions up to a cardiac standstill and death.

At home it is possible to keep to a diet of 1000 calories only up to 2 – 3 weeks. At deterioration in health a diet it is necessary to interrupt and see a doctor at once.

Essential lack of a diet of 1000 calories is also that after its termination initial weight is gained for short term. The organism perceives temporary deficit of food as continuous threat of its wellbeing therefore at recovery of a usual food allowance after a diet of 1000 calories superfluous calories begins to reserve for the future everything.

The lack of protein of the menu on 1000 calories a day leads to the fact that own protein of skeletal muscles begins to be spent for the most important processes of a metabolism. If to tighten a diet of 1000 days on time, then the cardiac muscle also is involved in this process that can provoke development of dystrophy of a myocardium.

If long to observe restriction of caloric content in a diet of the menu of 1000 calories a day, then from a lack of important nutrients often there is an uncontrollable weakness, the host defense, physical and intellectual force decrease, there are failures in a metabolism.

Over time to negative to menu effects on 1000 calories a day such problems with health as diarrhea, nausea, a hair loss, disturbances of a menstrual cycle, stones in a gall bladder, bad portability of cold will join.
