Who is on a diet?
Diet is common and popular. It is believed that about half of women of normal weight have tried dieting. A study found that almost 70% of 15-year-old girls are on a diet, and 8% of them have very strict diets. Another study found that approximately 70% of women and 45% of dieters are not overweight and do not need to follow any diet.
Before dieting, it is dissatisfaction with your body and the desire to lose weight.
A British study found that two-thirds of girls aged 14-15 and half of girls aged 12-13 want to lose a few pounds. Due to the pressure associated with this, about a quarter of young girls skip at least one meal a day.
Dietary risk
Diet increases the risk of eating disorders. Scientists have found that if adolescent girls eat moderately, the risk of eating disorders will increase by five times, and a strict diet will increase by 18 times.
Frequent, strict diet can lead to overweight. Ninety-five percent of people who lose weight through diets gain more weight in the next two years than they lose after dieting. This is because during dieting, people limit the number of calories and types of dishes, and experience constant hunger. Perhaps in a short period of time, dieters can ignore hunger, but after long-term dieting, appetite increases and overeating. In turn, this can lead to feelings of guilt and failure, which can exacerbate dissatisfaction with yourself and your body. Some people live in a similar diet cycle throughout their lives—that is, eating takes up a certain amount of their time and energy every day.
In addition, it has been found that diet slows down the metabolism-the rate of calorie burning slows down.
After a period of time after a person regains a healthy and adequate diet, the normal metabolic rate will be restored.
Strict diet will affect physical and mental health. There may be bad breath, fatigue, overeating, headaches and cramps, constipation, sleep disturbance, and bone destruction.
Diet can change the body's natural response to food, needs, and appetite. When a person no longer feels hungry and full, he may no longer distinguish his emotional needs from hunger.
Why do we go on a diet?
Many people of normal weight think that they are overweight and want to lose weight on a diet. In addition, many overweight people want to lose excess weight and believe that diet will help them do this.
As we all know, about one-third of the world's population is overweight, but about twice as many people want to lose weight.
They are dieting to be slimmer. There are many reasons for the world's pursuit of slimness, one of which is the equally common fear of getting fat. According to reports, this fear can already appear in elementary school students. For some reason, in our society, integrity is considered shameful and condemned.
Through advertising, people’s desire for dieting is supported by companies that focus on everything related to dieting (dieting, books, groceries, and other goods). Because we are in a lucrative industry, the catering industry is unnaturally optimistic about food. In fact, it has been found that half of dieters gain weight as a result-few of them can maintain the weight lost after dieting for five years.
The success of strict dieting depends on many physical and mental factors, and in obesity, it has a very poor effect on weight loss.
