What happens to your body when you eat 70 hot dogs in 10 minutes, and why would thousands of people watch you do it? We’re exploring the curious appeal of competitive eating, and its impact on our stomachs, minds and society around us.

What does the popularity of eating competitions tell us about our changing relationship with food? And why do humans appear to have such an appetite for watching other people regurgitate it?

In the second episode to explore the curious appeal of competitive eating, presenter Emily Thomas gives it a go, and speaks to a doctor about the potential risks. We find out what goes on inside the body of a speed eater and just how big their stomachs get. Is it nature or nurture that allows people to consume such vast quantities of food?

We also hear from a man who says competitive eating helped him get over anorexia nervosa, and find out what a psychiatrist thinks.

Competitive eating can be dangerous, especially outside of a controlled environment, so please do not try this at home.
