- Severe and deliberate limitations on the amount of energy consumed with food (calorie intake). For example, it may follow a well -known diet, or just count calories and set strict limits.

- Irregular eating:
- hourly diet;
- a 5: 2 diet (five days a week we eat normally and two days a week - we limit our food significantly);
- skipping meals;
- "Fasting day", which is the refusal to eat on certain days.
Who is on a diet?
Diet is common and popular. It is believed that about half of women of normal weight have tried the diet. One study found that nearly 70% of 15-year-old girls were on a diet and 8% of them followed a very strict diet. Another study found that about 70% of women and 45% of dieters were not overweight and did not need to follow a diet.
Diet is preceded by dissatisfaction with your body and the desire to lose weight.
A study in the UK found that two-thirds of 14-15 year old girls and half of 12-13 year old girls want to lose a few pounds. Because of the stress associated with this, about a quarter of young girls skip at least one meal a day.
Risk diet
Diet increases the risk of eating disorders. Scientists have found that if adolescent girls eat a moderate diet, the risk of eating disorders increases fivefold, and with a strict diet - eighteen times.
Frequent and strict diet contributes to excess weight. 95% of those who follow a diet to lose weight gain more in the next two years than those who lose as a result of the diet. This is due to the fact that during the diet, people severely limit the amount of calories and variety of meals, experiencing a constant feeling of hunger. Perhaps for a short time, nutrition can ignore hunger, but after a long diet, increased appetite and overeating occur. This in turn, engenders feelings of guilt and failure, which can increase dissatisfaction with yourself and your body. Some people go through a similar diet cycle throughout their lives - that is, the diet consumes part of their time and energy each day.
In addition, diet has been found to slow down metabolism - the rate of calorie burning slows down.
The normal metabolic rate recovers some time after the person returns to a healthy and adequate diet.
A strict diet affects mental and physical health. Bad breath, fatigue, overeating, headaches and cramps, constipation, sleep disturbances, and possible bone damage may appear.
Food can alter the body’s natural response to food, needs, and appetite. A person no longer feels hungry and full, he may stop distinguishing his emotional needs from hunger.
Why do we go on a diet?
Many people with normal weight consider themselves overweight and want to lose weight by dieting. Also, many overweight people want to lose extra weight and believe that diet will help them overcome this problem.
It is known that about ⅓ the world’s population is overweight, but about twice as many people want to lose weight.
They go on a diet because of the desire to be slimmer. The pursuit of slim around the world has many reasons, one of which is the same fear of being obese. It is revealed that such fears can already appear in primary school students. For some reason, in our society, equipment is considered something to be ashamed of and condemned.
Through advertising, the desire to go on a diet is supported by people by companies that focus on everything related to diet (diet, books, groceries and other items). Since we are in a very lucrative industry, the diet industry is indeed optimistic about diet. In fact, it has been found that half of people who go on a diet gain weight as a result - a small number of them are able to maintain the weight lost as a result of the diet for five years.
The success of a strict diet depends on many physical and mental factors, and in obesity, it is highly ineffective for weight loss.
