The Restaurant that Burns Off Calories
Maitre d' and Extraordinary Places to Eat host Fred Sirieix and GP Zoe Williams open a restaurant with a difference, welcoming 20 unsuspecting diners for a slap-up meal. It all sounds normal enough, but this restaurant has something unexpected back of house - a functioning gym, where a group of fitness fanatics are poised on exercise bikes, treadmills and rowing machines, ready to burn off every single calorie ordered and consumed by the diners. This groundbreaking stunt for science strand Horizon is based on the latest scientific research, which suggests that when we are shown the astonishing amount of exercise required to remove excess calories from our bodies, we choose to eat up to 20% less.
Fred and Zoe also delve into the science of calories, including why we need them and why we are collectively eating more than we are burning, a situation which has left nearly two thirds of the population overweight or obese. They examine new science, learning that our genes influence our weight, not by changing how we metabolise food, but by determining how hungry we feel. They also delve into our microbiome to discover how a healthy gut could help us burn fat.
