In this article there are plenty of correlations between obesity and lack of financial freedom. I agree with the author of this article and I just wanted to add that being fit or at least striving to be fit can help with ones financial situation. Take for example, you will eat out less because you are trying to lose weight or maintain your current weight. Although I live in California I do find that more people here do bike around town. It could be for financial reasons, it could be health reasons or even environmental reasons. These people will end up saving money they would've otherwise spent on buying gasoline.
Weight loss can definitely help shape ones financial situation and they are definitely correlated. Check out the article, feel free to comment below tell me what you think.
