Dr. Jason Fung, MD, is a nephrologist and expert in the use of intermittent fasting and low-carbohydrate diets for the treatment of Type 2 diabetes. In this presentation, delivered on Aug. 2, 2018, at the 2018 CrossFit Health Conference in Madison, Wisconsin, Fung shares his first-hand experiences navigating a broken healthcare system and discusses how he shifted his research and medical practices as a result.
Fung’s objectives for his presentation include:
- Understanding why long-term weight loss is so difficult.
- Introducing the concept of therapeutic fasting.
- Understanding some myths and misunderstandings associated with the fasting process.
He recalls treating obese and diabetic patients with traditional methods, which included what he characterizes as poor dietary recommendations and a slurry of drugs. He explains, “It became obvious that I’m just sort of holding their hand until they get their heart attack, until they get dialysis, until they go blind, until we chop their feet off.”
“It’s really sad to realize that the profession that you’ve chosen is not really helping people,” he says. This realization compelled him to diagnose the problems associated with traditional care and seek alternative treatment methods for his patients.
Fung historicizes what he calls “the modern eating pattern,” which emerged in 1977 in the U.S. with the development of the Dietary Guidelines for Americans. He notes the 1977 guidelines led to the consumption of more grains and sugars, which in turn led to people “eating often, eating late, and eating all the time.”
Incidences of obesity and Type 2 diabetes reached epidemic levels, and the most common treatments have long been drug interventions. Unfortunately, the prevailing non-pharmaceutical prescription — to eat less and move more — has a 99.9% failure rate. Fung observes that popular wisdom tells us to blame the patients and assume they did not adhere to the prescription. He claims a basic understanding of metabolism suggests otherwise, however.
He also explains why intermittent fasting is an effective alternative to traditional treatments for obesity and diabetes. The modern eating pattern keeps our insulin levels high all the time as we eat over long durations, and when insulin remains high all the time, Fung explains, our bodies store food energy as fat. Even when losing weight on a calorie-restrictive diet, the metabolism will slow, hunger hormones will increase, and the weight will eventually return. Intermittent fasting, on the other hand, allows insulin levels to drop, which puts us in burning mode rather than storing mode, and allows for greater hormonal control of energy partitioning.
Fung claims his recommendations are so effective that patients no longer need to say, “I have to go see my doctor to see what pill I need,” or, “I need to go see my doctor to see if he needs to stick a stent in me.” Instead, Fung explains, “We’re giving you the power to take back your own health, because you’re not gonna get it from anywhere else.”
Comments on Dr. Jason Fung: Fasting as a Therapeutic Option for Weight Loss
Good news I came across NEW HORIZON CREDIT 1 , I used to have a lot of sleepless nights due to my low (FICO) credit score that was below expectations ,can’t access loans and mortgage for the new house I was about buying for me and my lovely wife . New horizon credit1 has been able to bring up my credit score tremendously by monitoring my credit between the three credit bureaus and resolving issues with providers. They are always available when I call. They take their time to discuss progress on my case and keep me updated. After about four working days of contacting them I was shocked to discover my credit score went from 650 -780 . Now I just got approved for a mortgage ! .
I highly recommend NEWHORIZONCREDIT1ATGMAILdotCOM ,
because their representatives are helpful ,hardworking and they also do what they say , fix your credit !
What a great relief for my dad's business pages on Facebook / Instagram accounts after it got compromised by a yet to be identified strange person ,all of a sudden he got locked out of his personal and vital business pages. As the only admin on several groups that he runs for real estates in Italy with over 15k members . He is completely at a loss here because he can't make a new profile because of hundreds of important business and personal contacts on his pages that are very critical to his online businesses and websites. Thanks to (fixurworries ATdoctor DOT com) who finally retrieved his Facebook/Instagram accounts within 48 hours.
It really is incredible that a *seemingly* simple problem like an excess weight has proven so difficult to manage. Calories in/Calories out has been the prevailing dogma and that dogma is not working. While it may be scientifically true, that negative energy expenditure results in weight loss, there is something missing in the implementation of this principle with respect to food quality and importantly human behavior. Intermittent fasting, along with time-restricted feeding, show promise in modifying *how* people eat for favorable health effects. Great share, the challenge is how society can change as a whole and accelerate the adoption of promising principles like IF/TRF that have some demonstrated efficacy both scientifically and behaviorally.
I'M DEAF I would really appreciate CLOSED CAPTION on DR FUNGS video.. there are no options for this.
Kaitte, there is a full transcription of the lecture provided in the footer of the post. I hope this is helpful to you!
HQ is doing thousands a huge favor familiarizing them with Dr. Jason Fung and his ability to articulate the role insulin plays in our health. Out of our group alone, called FASTERS, in the last 2 years who employ CrossFit principals and intermittent fasting, over 300 are no longer on medication .
Fantastic results! If only the type of approach you're employing was more more widespread.
