Leptin helps with weight loss! Is the lazy sleeping method really useful?

Can you lose weight while sleeping? In recent years, the "sleep weight loss method" has become popular in Japan, which advocates that adequate sleep can increase leptin in the body, thereby suppressing appetite and helping to lose weight. This has made many women who are losing weight keen on becoming "sleeping beauties"! However, doctors say that not all leptin can actually help with weight loss, and people cannot achieve weight loss effects by sleep alone. They still need the coordination of lifestyle, diet and exercise.

There is a popular weight loss method that claims that one can lose weight just by sleeping. It claims that adequate sleep can stimulate the secretion of leptin, thereby suppressing appetite and helping with weight loss.

The more you sleep, the thinner you get! Leptin appetite suppressant becomes a trend

Leptin is one of the many hormones in the human body. It mainly acts on the hypothalamus, suppressing appetite, reducing food intake, and increasing energy and calorie consumption, thereby maintaining body fat content. Since adequate sleep helps the body secrete leptin, in recent years people have been encouraging people who are too lazy to exercise to try the "sleep weight loss method". The longer you sleep, the more leptin you produce, and the faster you lose weight!

The more leptin the better? Doctor: Leptin may be "ineffective"

However, Xie Mingjia, CEO of the Weight Management and Diabetes Health Management Center of Changhua Christian Hospital and physician of the Department of Endocrinology and Metabolism, said that most of the medical research on leptin and weight loss in the literature are small-scale studies, and it is currently impossible to prove how much sleep is needed to achieve the maximum secretion of leptin, or even how much weight loss effect is achieved.

Leptin, like other hormones such as growth hormone and cortisol, has a secretion amount that changes regularly during the day and night. If the regularity of secretion is disrupted, it will affect the body's functions and lead to obesity. If you do not get enough sleep for a long time, especially if you need to work in shifts, your hormone secretion will be disrupted and the calories you eat cannot be completely consumed and metabolized. Obesity will naturally occur, and even diabetes and heart disease will not be spared.

Domestic weight loss experts say that obesity cannot be eliminated by sleeping alone. It is still necessary to adjust factors such as lifestyle, diet and exercise to truly "enjoy thinness."

In general, whether you are working the day shift or the night shift, as long as you have a regular work and rest schedule and get enough sleep every day, you can increase the secretion of leptin during sleep, allowing it to play its due function of suppressing appetite, which "may" be more helpful for people who want to lose weight to control their weight. Generally speaking, the physiological adaptation period for switching between day shift and night shift takes at least one week.

However, Dr. Xie Mingjia said that the causes of obesity come from lifestyle habits, diet and diseases. It is impossible to easily lose weight by simply changing sleep habits. In addition, the weight loss effect of leptin is not as good as imagined. Even if sufficient sleep can stimulate leptin secretion, some people's fat cells cannot interact with leptin, making these leptins "invalid", making it difficult to achieve the expected weight loss goals of suppressing appetite and calorie consumption.

Sleeping longer reduces your basal metabolic rate and eating less will naturally make you thinner

Jiang Shuwen, a nutritionist at the Nutrition Department of Wan Fang Hospital, believes that sleeping too long will lower the body's basal metabolic rate and reduce food intake, which will make it easier to lose weight. Therefore, weight loss cannot be directly equated with the concentration of leptin produced during sleep. In order to achieve the effect of weight loss, you still need to comprehensively consider external factors such as food intake, activity level, fat ratio, etc. Only by taking all aspects into consideration can you really lose weight quickly.
