Then decoy or real advances in nutrition and dietetics? If the income of today we offer more, as in the past century, eating soap or do not drink a drop of water to lose weight (see History of weight loss), it is very difficult to find All these schemes. Which are effective, or otherwise dangerous? Early review of dieting …

A case reserves and expense

The weight reflects the balance between food intake and energy expenditure and excessive energy intake is stored as fat reserves. If energy intakes are too high, the stock rises and it grows, but if we reduce these contributions, the body draws on its reserves and you lose weight. It is on this simple principle that rely most plans.

Choose carbohydrates to lipids

Among the dietary energy, sugars – or carbohydrates – are the fuel energy used at the earliest. The body fat – or fat – excess are more easily stored in adipose tissue, while excess energy provided by proteins are burned.

Therefore prefer carbohydrates to fat, provided they better preserve the organs and muscles and creates a stable weight after weight loss. Some plans use these principles to select as food or delete another. Finally, plans to use the principles of chrononutrition taking into account biorhythms nutrition during the day.

Fats are the resistance

But by remaining fixed on food intake, often overlooked component of energy expenditure, then it is essential to also act on it to get maximum results.

Finally, to lose weight permanently, you must have the time … If you lose weight too quickly, we risk the return just as quickly, and especially to have trouble losing it again: The agency has retained memory blackout periods and will save significant expenses to meet. It is a kind of resistance to plans that installs and weight loss becomes increasingly difficult.

So to succeed in stabilizing its weight, lose weight progressively better while adopting sustainable lifestyles: diet and exercise.

While many of them bind diet when they do not need it, they agree that these periods are very difficult mentally.

diet change in depth

To diet is not a natural approach! This changes the eating habits, and thus marks that punctuate everyday life: organization of courses, choice of food (when it is not to replace bags and cocktails for weight loss), meal preparation … As noted Duboys Matthieu de Labarre, a sociologist at the University Victor Segalen Bordeaux, “the system requires constant vigilance, organization, anticipation, time and energy.

According to a CSA poll / OCHA in 2003, the plans require sacrifices that will put to evil :

• 77% of women find that dieting is very difficult;
• They are well over 73% have often wanted to crack;
• Half of those who follow a diet they feel will deprive them of what they like;
• And this impact is not only food as more than 20% of women acknowledge avoid meals with friends and social relationships as they are on a diet.

The size of food friendly and goes by the wayside … It’s hard to diet until the end in these conditions. Many are seeking then to find support, particularly from their surroundings. Do not laugh at all those posting their status as women “on diet” is a way to get help.

Arrangements to depression

All these constraints are not without effect on morale. As we know, food is often a pure pleasure and comfort, true allies of stressful or difficult times. You can practically draw a parallel with a smoker who cannot take a cigarette to feel reassured. And the gap or crack due to enter more than necessary will and self-esteem: it is not strong enough, we do not know how to take control … So it is not uncommon for a diet is accompanied by small strokes of blues and even heavy depressed.

The professional thinness!

But as pointed Duboys Matthieu de Labarre, face the difficult test of the system is not necessarily negative. Thus, these women often bind these blackout periods acquire many skills. Not only do they believe less and less to the miracle products, but they eventually learn to manage their cravings and balance their diet rather than restrict it. Their goals are more realistic and they try to keep the pure pleasure…

Despite these developments, which may be positive, enter the spiral diets is often synonymous with hell. And again the medical monitoring is invaluable: it avoids errors nutrition, and especially provides essential psychological support. But to avoid losing the moral, we should stop losing weight, especially when it’s useless!
