last weeks : what i want to learn about

I am curious to learn about obseity throughout the world. This has always been an issue worldwide and I want to learn more about what causes it. Learning about different peoples views will help me think more and might be beneficial for a future research paper. I want to learn different foods and excercises that are just good to have and use ingeneral with out obesity. Im interested into learning about the trends of other countries and the game plans of attack from people with obesity trying to conquer it.
