The number of people who are at risk of serious health problems due to being overweight is increasing. What is the reason for the growth in overweight people in society? How can this problem be resolved?

Nowadays overweighting become a huge social problem because a number of people have serious health issues due to their overwight. I think that there are three reason for the growth in overweight people in society. Firstly, most of the people do not have knowledges about food and nutrients (exept of obvious like fried poteto is bad, cucumber is good). Nobody knows how much calories do they need for the day, how many nutrients do they have to get from food and which meals could fit for their needs better. This is the reason why people eating "bad" food. Secondly, we have strong bodypositive movement which saying that being overweight is normal and you you shold't do anything about that. So this people trying to live with eyes wide closed on their heath problems. Thirdly, unhealthy food is more reachible than healthy. You can't just go to the shop and buy healthy food, you need to reed all the boxes to find somethig with no added shugar for example. In my opinion there are a numbers of ways to solve this problems. I will provide just three examples. First way is to set a lesson about rations and diets at schools to provide elementary knoledges about food and healthy eating. Pupils can learn a lot about nutrients, calories, different diets and their oun needs. This way they can start thinking more about what they eat and it will be a healthy habit even when they will grow up. Second way is to make social advertisment about being bodyneutral is better then bodypositive. It means that it is good to take you body as it is but it is still good to try to improve it to make it healthy. And third is to make some tax preferences for shops with healthy food.
