Want to know why we are losing the war on obesity, type 2 diabetes and cancer? We don’t admit to problems. And the first step to solving a problem is to admit that one exists, says Canadian nephrologist Dr Jason Fung.

Fung has a special interest in weight management and diabetes. He says that there’s a terminal malaise affecting all of public health. It’s that the “experts” don’t welcome dissenting opinions.

Rather than acknowledge the truth, they pretend that everything is just fine, thank you. No one wants to yell: ‘The emperor has no clothes!’

That’s despite an obesity and type 2 diabetes epidemic that dwarfs anything the world has ever seen. And rising cancer death rates. Here’s what Fung believes doctors and researchers should do – starting with changing dietary advice. – Marika Sboros
