When many people start to lose weight, especially some white people, think that eating less, eating less or even dieting can succeed in losing weight.
Dieting can lose weight only because of calorie intake. This is the root of calorie deficiency, and any method of losing weight can not be separated from this.
But when we go on a diet, because we eat very little food, it will make our intake of calories disproportionate.
Suppose the calorie to maintain your current weight is 2000 calories. This intake is guaranteed to be neither fat nor thin, just to make you live comfortably.
If you want to lose weight, the scientific and healthy intake is 2000 calories MINUS 500 calories, which is 1500 calories.
When you are on a diet, you may only consume 500 calories. This intake is extremely low, which will make your body enter a state of "self-protection". In other words, your body will automatically shut down some functions that need to consume calories, such as your brain.
According to a research document from King's College London, in the study of 596 young women aged 1 1- 18, dieting greatly reduced their IQ.
Another research document shows that people aged 65 are more prone to cognitive impairment and Alzheimer's disease when dieting.
Another research document shows that when rats go on a diet, neurons in their hypothalamus will devour their organelles and protein. When this happens, we will feel even hungrier. Because the hypothalamus is mainly responsible for managing physiological mechanisms such as sleep.
Therefore, greatly reducing the proportion of calorie intake will make the body uncomfortable and enter a state of self-protection. In severe cases, the body will "eat" the brain to survive.
Then, if you rely on your strong willpower to successfully lose 10 kilograms, but don't be happy, if you rely on dieting to lose weight, your weight will soon rebound.
Before talking about the research literature, let's learn about two human hormones that have a great influence on appetite: leptin and auxin.
The main function of leptin is to control calorie intake, increase energy consumption, inhibit the synthesis of fat cells, and make us thinner. The secretion of leptin is negatively correlated with food. When leptin increases, appetite decreases. When leptin decreases, appetite increases.
The main function of auxin is to stimulate hunger and promote gastric emptying and gastric acid secretion. There is a positive correlation between auxin and food. Auxin increases and appetite increases. Auxin decreases and appetite decreases.
In a research document, they gathered a group of people weighing about 94 kilograms to go on a diet to lose weight, consuming 500-550 calories a day. Within 10 week, they lost about 13 kg on average, but after 10 week, the researchers tested their hormone levels and found that leptin decreased significantly and auxin increased significantly. Obviously, after one year, most subjects regained 7-8 kilograms.
Therefore, it is impossible to simply diet to lose weight unless you can really diet for a lifetime. But in this process, your brain will be "eaten", not to mention for a lifetime.
