When it comes to weight loss, most people think of eating less and exercising more, but a study found that if you respect the body’s biological clock, that is, go to bed at night and wake up at dawn, you can avoid weight gain. Once the original circadian rhythm is disrupted, the stress hormone “glucocorticoid” secreted by the human body will continue to be secreted. Even if the food intake is not increased, the weight will increase significantly, and the secretion of insulin will increase, which will increase the risk of metabolic diseases such as diabetes and fatty liver. risk.
Nephrologist Jiang Shoushan shared a study published in the “National Library of Medicine” last year on his Facebook. When the secretion is abnormal, it will affect the state of body weight and insulin secretion.
When the human body encounters stress during the day, the secretion of glucocorticoids is high, and there will be a short-term peak to increase the catabolic activity of the human body and help prepare for the fight or flight response; when the human body rests at night, the secretion of glucocorticoids The circadian rhythm makes the secretion of glucocorticoids peak and valley. However, if a person does not sleep at night and sleeps during the day, glucocorticoids will continue to be secreted, which will flatten the original secretion curve in the circadian rhythm oscillation mode.
The researchers let a group of mice receive light at night to make them secrete glucocorticoids at night. The mice would sleep during the day because they did not sleep at night, but because the bright environment during the day hindered the secretion of melatonin, they also Let the glucocorticoids continue to be secreted. The researchers found that the mice showed hyperinsulinemia after 3 days, and their fat cells more than doubled after 21 days.
Jiang Shoushan said that the above research shows that if the normal biological clock is violated, that is, if you don’t sleep at night and sleep during the day, your body will start a process that promotes the growth of fat cells and stimulates insulin secretion, which in turn promotes fat storage, increases insulin resistance, and improves The incidence of metabolic syndrome such as fatty liver and diabetes, “On the contrary, if you go to bed at night and wake up at dawn, you can lose weight naturally.”
