Reversing Type 2 Diabetes

Can a person be "cured" of Type 2 Diabetes? Dr. Sarah Hallberg provides compelling evidence that it can, and the solution is simpler than you might think.  Dr. Sarah Hallberg is the Medical Director of the Medically Supervised Weight Loss Program at IU Health Arnett, a program she created. She is board certified in both obesity medicine and internal medicine and has a Master’s Degree in Exercise Physiology. She has recently created what is only the second non-surgical weight loss rotation in the country for medical students. Her program has consistently exceeded national benchmarks for weight loss, and has been highly successful in reversing diabetes and other metabolic diseases.

Dr Sarah Halberg on Carb Restriction at Crossfit HQ

Dr. Sarah Hallberg made several career pivots—all fueled by her anger at unscientific and harmful practices perpetuated by the medical community—before becoming Medical Director at Virta Health. In this talk, delivered on Dec. 15, 2018,  CrossFit Headquarters, she  speaks about some of those unscientific and harmful practices, specifically those pertaining to the management of obesity and Type 2 diabetes (T2D). She outlines the physiological problems inherent in treating T2D with insulin, the benefits of treating the disease with a carb-restrictive diet, and the data from a recent Virta Health study that demonstrates the positive effects of carb restriction.

Hallberg delved deeply into the scientific literature on obesity. Her reading was fueled by a curiosity about why, when she was a physician, none of her patients were losing weight with the recommended low-fat diet. She soon discovered there was no scientific basis for this recommendation. There was, however, a considerable amount of data supporting carb restriction, so this is the treatment they recommended through the Indiana University program.

After Hallberg performed a TED Talk at Purdue University, 500 people enrolled in the program. Not only did those who followed the low-carb recommendation lose weight; many were cured of T2D as well. Hallberg notes that after one year, “60% of the patients with Type 2 diabetes had reversed their diabetes,” and 83% of participants were able to adhere to the diet.

Sugar is Killing Us

Sugar is Killing Us is a campaign to spread information about the negative effects of sugar and empower people to make better food choices.


The Truth About Sugar - a  BBC Documentary from  2015 - aimes to demystify some of the myths about sugar - namely, what food products secretly contain it - and demonstrate the impact it can make on your health if you reduce the amount you eat.  It charted the lives of Cara Patterson, Rick Shabilla, Audrey Cannon and Simon Gallagher, who consumed nearly 119 teaspoons of sugar between them a day. Three of them lost nearly six kilograms each after implementing a low-sugar diet, but Shabilla unfortunately decided to replace his Indian sweets habit with lager and was not as successful. 

Journalist Fiona Phillips is on a mission to find out the truth behind the recent headlines on sugar. She discovers why some of us have more of a sweet tooth than others, which sugars you can enjoy guilt-free, why there is so much sugar hidden in food you would think was purely savoury and what effect sugary drinks have on the appetite.

Dr. Fung on Intermittent Fasting

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, 

Dr Fung’s  - talks about:

  1. Understanding why long-term weight loss is so difficult.
  2. Introducing the concept of therapeutic fasting.
  3. Understanding some myths and misunderstandings associated with the fasting process.

Fung explains why a significant reduction in caloric intake leads to a decrease in basal metabolism. This biological inevitability is ignored by the proponents of the “calories in, calories out” fallacy, he observes.

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.
