题目：In some developed countries people become fat because they eat too much junk food and processed food. Suggest some ways that governments and food companies can encourage people to stay fit and eat a healthy diet.

According to the data survey, The obesity rate of the US population is as high as 40%, and the obesity rate ranks first in the world, and more than two-thirds of the population has a tendency to become obese. The reason for the obesity of Westerners is mainly due to the diet, and the intake of a large number of high-sugar beverages and high-protein foods cannot be consumed at all. Western governments should promulgate policies on fitness and encourage obese people to increase fitness time, so that people's physical fitness is enhanced. Another most important point is the establishment of health awareness. When people have health awareness, they will naturally pay attention to their body shape.
