Does paying attention to diet and exercise equal weight loss?

　　Pay attention to diet and exercise equals weight loss

　　If you think that just doing these two things is enough to ensure weight loss, you are totally wrong. You may be overlooking another major factor: sleep problems due to weight loss. "Americans get the least amount of sleep globally," said Dr. Ivie Van Keout, who studies sleep at the University of Chicago. As you know, Americans are the most overweight and obese.

　　Perhaps we should consider the possibility that obesity and sleep may lead to appetite disorders. ”She and another sleep researcher, Es-Tesari, also from the University of Chicago, tested the hormone levels in people who could not get enough sleep. The test results showed that everyone has the normal sleep time they need. If the sleep time is less than this time, even if the difference is only one hour, it will lead to hormonal imbalance in the body.

　　After analyzing the blood of these sleep-deprived people, it was found that their blood levels of leptin, which controls appetite, were reduced.

　　When our food intake reaches a certain level, leptin will "tell" us that we are full. At the same time, the plasma ghrelin content in the blood increases. The function of plasma ghrelin is that when our body's caloric supply is insufficient, it sends a hunger message, thus prompting us to start eating.
