Dr Jason Fung’s single best weight loss tip!

 By Marika Sboros

Psst! If your MD or dietitian still subscribes to the CICO (calories-in, calories-out) obesity model, find another one. Quick!

According to the model, obesity is from gluttony and sloth. A calorie is a calorie. And all you have to do to lose weight and keep it off is “eat less and move more”.

The model is not just unscientific, it’s out the dark ages of nutrition science.

Yet many (if not most) MDs and dietitians still believe that CICO rules. Canadian nephrologist Dr Jason Fung is not one. As a kidney specialist, Fung sees many patients with obesity and type 2 diabetes. The two conditions are now so common that doctors refer to them as “diabesity”.

In the article below, Fung gives his top weight loss tip for those struggling with diabesity. Spoiler alert: it’s about as far from CICO as it’s possible to be.



Fasting: Fung dishes up quick science to reverse type 2 diabetes

By Marika Sboros

Fasting is as old as the hills of ancient Greece. Many doctors and dietitians still dismiss it as a fad. It is proving its worth in modern medicine’s arsenal to beat type 2 diabetes.

Planned intermittent fasting may help to reverse type 2 diabetes, a condition that is now epidemic across the globe. That’s according to Canadian doctors in the journal, BMJ Case Reports. Three male patients in their care were able to cut out the need for insulin treatment altogether after a period of planned intermittent fasting.

One of the co-authors is Canadian nephrologist (kidney specialist), Dr Jason Fung, of the Department of Medicine at Scarborough General Hospital in Ontario. Fung is an expert in fasting interventions to reverse type 2 diabetes.

He and his co-authors readily admit to the limitations of the case reports: small in number and men only. The implications, however, are “huge”, Fung says.



KETOGENIC DIETS FOR CANCER: FUNG FOCUSES ON MYTH, MAGIC, PARADOX

One of the most exciting areas of cancer research currently takes inspiration from the Warburg Effect. Researchers base that on the work of German physiologist and Nobel laureate Dr Otto Warburg in the 1920s.

Warburg described ‘aerobic glycolysis’ – a defect in mitochondrial glucose metabolism. He showed how it causes fermentation of glucose and diverts glucose from energy production to cell growth. That has given rise to the ketogenic diets as adjuncts to conventional treatment methods for cancer. 

Canadian nephrologist Dr Jason Fung has a special interest in weight management, diabetes and cancer. Not the least because many of his patients are obese diabetics. And research shows that diabetes significantly ups the risk of cancer. 

Fung says that the simplistic notion that a ketogenic diet may ‘starve’ cancer cells of glucose does not hold up to the facts. Indeed, in certain cancers, he says that glutamine is the more important component. Here, he looks at the implications of the ‘paradox’ of the Warburg effect. – MARIKA SBOROS



WHY WE’RE LOSING OBESITY, DIABETES, CANCER WARS

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
