Short Intense Workouts Reverse Diabetes and Create the Healthiest Metabolism that Prevents Cancer, Heart Disease and Lung Disease
I am from a family of long distance runners—I am also from a family prone to type 2 diabetes. About ten years ago, I was shocked to find that sustained endurance exercise was not correcting my high blood sugar and in fact, blood test results indicated my cardiac health was not so good. That was then and this is now. And this recent study adds to the body of evidence showing that a different kind of exercise works.1
Enter high-intensity-interval-training (HIIT). This study included men and women, average age of sixty, with a diagnosis of type 2 diabetes within the prior 3-6 years. They were divided to follow either the “standard of care” of exercise for diabetics, or a 20-30-minute interval workout with strenuous resistance mixed in, three-days-per-week for twelve weeks.
The pre and post measurements included cardiac muscle structure via MRI, metabolic blood tests and body fat. The results display benefits similar to many other studies that introduce strenuous exercise for people with insulin resistance. Less body fat, fatty liver significantly reduced and blood sugars dropped. But this study, with the MRI analysis, indicates that cardiac structure and function both significantly improved in the HIIT group.
Did I hear that correctly? The heart muscle itself gets healthier in form and function in only twelve weeks of three-days-a-week exercise. I can assure you that “walking” does not show this kind of benefit.
The data indicated some other interesting changes over the three months. The people following standard of care didn’t just miss-out on the disease about-face, but their blood sugars actually increased, liver fat increased along with their 2-hour post meal blood sugar. In essence, their type 2 diabetes was progressing right along with standard treatments.
It’s a wake up call for anyone experiencing high blood sugars, insulin resistance and type 2 diabetes. It’s also why, in my metabolic specialty practice in Portland Maine, I have developed a metabolic recovery fitness program (IN VIDEO FORM HERE) that doesn’t include walking or jogging at all. And in the two thousand square foot fitness facility at my office—there is no treadmill.

The Blood Code Fitness Principles to Correct Insulin Resistance
1) Exercise on an empty stomach.
2) Exercise strenuously and vigorously.
3) Engage many muscle groups whenever possible.
4) Vary your heart rate throughout.
