The Institute of Economic Affairs argues that the food industry is being unfairly blamed for obesity, and that we are eating less than ever.

The report argues that it is a lack of exercise, not eating too much, that drives obesity.

However, some have criticised the report as “laughable nonsense” and says that the report misses one crucial point – that people lie about how much they eat.

On Channel 4 News on Monday night the difference in opinion was plain to see – check out the debate between Christopher Snowdon from the Institute of Economic Affairs and Professor Mike Lean, the Chair of Human Nutrition at the University of Glasgow, below.
