Usually, people tend to lose weight because of lack of sleep and hard work. But this is not absolute, because there is another important factor to consider: nutrition, nutrition plays a decisive role in human obesity. If you don't get enough sleep and study hard, you will consume a lot of nutrition. If nutrition can't keep up, people will lose weight. However, according to relevant data, if there is adequate nutrition, the result is just the opposite: many people have become fat. This may be caused by factors such as lack of sleep, such as endocrine disorders and abnormal fat metabolism.

Therefore, while studying hard, we should strengthen nutrition and pay attention to proper exercise. Only in this way can we maintain good physical fitness and study status.
