Nowadays, it is evident that the presence of fast food is responsible for obesity to some extent due to its low prices. To tackle this problem, it has been suggested that governments ought to implement a high tax on fast foods to minimise the consumption of convenience meals. I personally believe obesity occurs because of the low prices of fast food and the government plays a crucial role by increasing the tax and prohibiting the advertisement of fast food will discourage young people ,especially those who have less money from buying food at quick service restaurants.
