Obesity has become a serious global problem. We need to do more to understand its prevalence if there is any chance of winning the fight.

I like this idea of using social media data on food and activity to map locations with a higher risk of obesity.
Excellent idea. By mapping obesity, especially in children, you can identify the most affected areas and caustive factors, which can help you fight the problem early on.
