People who lack sleep may be prone to obesity. If you don't sleep well, you may eat at night and increase your calorie intake. In addition, people with poor sleep may have some hormone secretion disorders, such as high insulin secretion at night, which will also promote fat synthesis.

People who sleep badly are not all fat. Some people have poor sleep, accompanied by anxiety, eat less, and may lose weight. So obesity is a comprehensive factor. Generally speaking, if you eat more, exercise less, and consume more energy than you consume, this is the most likely cause of obesity in physics.

I still advise you, if you have sleep problems, actively come to the hospital to see a doctor and rule out some organic reasons. If it is a simple sleep disorder, you can also use some anti-insomnia drugs to help regulate sleep.
