The obesity issue has gradually become a worldwide problem nowadays. The average body mass index of person is increasing, while the standards of health and fitness are getting worse significantly. This problem might be due to lots of factors. In this essay, I will outline two major reasons and solutions to these problems.

One reason for the increase of average weight of individuals is the change of balance diet and food issues. With the improvement of people’s living standards, they have more choices for foods. That leads to people preferring eating more refined food instead of grains.Besides , industrial processed food and fast food are bought by more and more workers because they don’t have enough time for cooking, and these food are cheaper than those expensive light meals. All of these cause people in contemporary society to eat food that are high in oil, salt, and sugar，which may increase people’s weight quickly.

Another reason for obesity is a sedentary lifestyle of people. With rapid development of social economy, the automatic level in our society has increased dramatically, and manual jobs has declined. At the same time, with the popularization of vehicles and electronic entertainment products, people prefer staying at home or in office to do sports. In other words, people eat more but sport less.

To solve these problems, establish rewards and punishments system is a useful way. For the food issues and balance diet, suitable rewards and punishments can ensure the safety of food industries, prohibiting too much industrial processed items into meals. It could achieve food health ratio and change people’s dietary structure further. For the lifestyle of people, rewards and punishments can encourage them to exercise and keep fit. For instance, companies can give some rewards and encouragements to staff who does enough exercises.

In conclusion, obesity and healthy issues are caused by changes in food and diet, and modern sedentary lifestyle. Establishing rewards and punishments systems to raise public’s health awareness and control weight at a suitable level can be effective methods to solve this problem.
