Can We Use Fat for Fuel?

Humans suffer from more chronic and debilitating diseases today than ever before; more than half of all Americans struggle with chronic illness, and 1 in 5 deaths in the U.S. are obesity-related. These discouraging statistics are largely the result of an inappropriate diet.

Most of us eat far too much sugar and grains, and far too little healthy fat. Unfortunately, the notion that glucose is the preferred fuel for your body is a pervasive one.

Everyone from diabetics to top athletes are advised to make sure they eat "enough" carbs to keep their systems from crashing. This misguided advice is at the heart of many of our current health failures. It's also a driving factor in our diabetes, heart disease and cancer epidemics.

Dietary fats are actually the preferred fuel of human metabolism, this can be traced back to our evolutionary roots. One of the keys to long-term weight management and good health is healthy mitochondrial function. For that, you need to get your net carb, protein and fat ratios correct.

This is the focus of my friend and colleague, Dr. Joseph Mercola’s latest book, "Fat for Fuel." This interview between Dr. David Perlmutter and Dr. Joseph Mercola digs deep into the key principles of “Fat for Fuel” and how we can finally reverse chronic disease and protect ourselves from cancer and other life-threatening illnesses.
