People who are interested in losing weight should concentrate more on how much they eat rather than doing exercise, a leading surgeon says.
Lord McColl of Dulwich also criticised the UK government's focus on promoting exercise as the key to tackling the obesity epidemic.
His comments came despite the scientifically proven fact that regular exercise results in a lower risk of many chronic diseases - including heart disease and type 2 diabetes.
And his view also flies in the face of research that shows it can also boost self-esteem, mood, sleep quality and energy - as well as reduce risk of stress, depression, dementia and Alzheimer's disease.
"We are in the middle of the most serious epidemic to have hit this country for 100 years - the obesity epidemic. The cure is free - you just have to eat less," the Daily Mail quoted him as saying.
