With the rapid development of China's economy, people's life is getting better and better, and their spare-time life is no longer so single. My hobby is surfing the Internet with my mobile phone and learning about current world affairs. But I saw such a news on the Internet that a young man in Ningbo, Zhejiang lost 90 pounds in order to join the army. His original weight was 240 Jin, but I didn't expect that he could lose 90 Jin in just one month. I admire the perseverance of this young man in Zhejiang. His spirit of self-discipline is worth learning from each of us. As I said above, China's economy is developing rapidly, and everyone's life is getting better and better, but it is because many young people live comfortably, eat well and sleep well, and lack of exercise leads to many young people getting fat. Now more and more young people are getting fat. Now obese people are mainly divided into young people and children. It is because their life is too good that obesity will find them. But we should know that obesity does great harm to our health. Some people do not exercise in time and lose weight in time after obesity, which leads to getting fatter and fatter, which is harmful to their health. Some people even think that obesity is just a matter of personal image and will not cause harm to the body. In fact, this idea is all wet. Obesity is very harmful to health, which may induce "three highs" diseases, because after obesity, human blood lipids and blood sugar will be easily affected, which will lead to endocrine disorders, and at this time it is easy to induce hyperglycemia, hyperlipidemia and hypertension, which is what we often call "three highs". In a word, we must control our diet reasonably and take part in outdoor sports more. Even if we really get fat, don't be afraid. You should have enough self-confidence and self-discipline to lose weight. Just like this Zhejiang guy, he lost weight successfully for his dream of joining the army. His perseverance is worth learning from each of us. ?
