This system attempts to predict whether you have lower or higher body mass index than the average American by asking approximately 20 questions about the food you eat. Take this short quiz to test our accuracy.

The system is based solely on publicly available Twitter data. To find out more about it, visit our project's home page.

You can also help our research by signing into your Twitter and/or Instagram account below. We only look at public profiles and posts; we will not share any identifying information about you.
