Calories

Calories are a national obsession but are they really worth counting?

Dr Chris van Tulleken takes nine randomly selected supermarket foods to an independent testing laboratory and discovers that only one of the labels matches the calories in the packet. The calorie count of all the other foods is up to 10% above or below the number on the label.

Three Glasgow families take Chris's Big Calorie Challenge to find the best way to burn off calories. Surprisingly, they discover they're better off doing the housework than going to the gym.

Chris's ultimate goal is to find out how we can cut our calories but keep eating our favourite treats. He discovers some kitchen secrets to strip 360 calories out of a luxury meal of steak, chips and cream pudding without changing a single ingredient.

This programme shows how we can all be healthier by eating smarter - without taking the joy out of food.
