Are you happy with your body? Do you have a problem with obesity? Are you counting calories, exercising, and struggling to lose weight? In between counting calories, exercising, and insulin, we need to learn about leptin, the most naturally effective weight-loss drug hidden on your body
Leptin, a hormone secreted by adipose tissue in the body, its main function is to let the body of other organizations, especially the brain, to know that the current energy, namely how much fat reserves, so as to regulate the body's heat balance, that is, how much we need to add quantity of heat, and can consume many calories, appetite is big is small, and various body functions to what extent can be started.
Leptin is mainly received by the hypothalamus in the brain. When the hypothalamus receives enough leptin, it will suppress appetite, improve energy metabolism, encourage the body to carry out high-energy activities, and even make the muscle tissue break down some fat, so as to ensure the body's fat reserves will not exceed the limit. The amount of leptin secreted basically corresponds to the amount of fat in the body, meaning that people who are fatter have higher levels of leptin
Then you may ask: if so, why are there still fat people in the world?
This is because of so-called leptin resistance.
It is often said that it is not advisable to lose weight on a diet, and there are reasons for leptin resistance. In a leptin resistant state, the hypothalamus receives very little leptin signal despite high circulating leptin levels, so it thinks we have insufficient energy reserves, which stimulates our appetite and lowers our metabolism, so we start eating more and moving less. Fat people have high levels of leptin, but when they resist leptin, the hypothalamus thinks that only at these levels will they not starve to death. If we lose body fat through dieting, causing leptin levels to drop, our imagination becomes horribly panicky -- "starving to death! No, eat right away for energy... "
So there's a reason diets often rebound.
So why leptin resistance?
As we know, too much exposure to one thing decreases sensitivity, and so does the cell. Always having high levels of leptin in the blood reduces the sensitivity of the brain to leptin; Secondly, circadian rhythm disorders and excessive eating frequency also lead to leptin resistance, which is influenced by the biological clock to respond to leptin signals. Also, eating dinner too late can lead to leptin resistance.
So what should we do about leptin resistance?
- Eat less frequently
- It's best to eat dinner four hours before bedtime
- You'd better not eat one meal a day
- More sun during the day, less blue light at night
Lose weight not only to have a method but also to understand the principle, I hope the introduction of leptin can help you!
