Why is it difficult for so many people to have a healthy lifestyle these days?

           Nowadays, if you go out with your friends or family, you will find all kinds of food with higher calories and sugar around you. So, it is hard to have a healthy lifestyle because the companies of fast food are increasing and spreading around the world such as MacDonald's, Domino's pizza and KFC. Also, the people are eating fast food because of working or studying and do not have time to cook, even though they know the impact of fast food. We can realize that many marketing sell unhealthy food and encourage people to buy it and make great offer on it. In addition, people spend their leisure time to use electronic devices such as computers, cellphones and TV instead of exercise. They are use easer way and do not move like use elevators instead of stairs or parking near the store. As a result, today in the united states roughly 200 million people overweight or obesity. Finally, I hope people educated and change their lifestyle to better and become healthier.
