The Real Truth About Keto, Fasting and Longevity: Jim Howard
Play • 44 min

What is the importance of biofeedback for longevity and improved physical performance? How can we accurately measure whether we are in ketosis? What is intermittent fasting? What impact does an 18:6 diet really have on our bodies? What is autophagy? How does fasting affect muscle mass? What are exogenous ketones? What does it mean to be metabolically flexible? 

With all of the conflicting information surrounding ketosis, fasting, the impact of exogenous ketones, and nutrition as a whole, we wanted to get an expert on the SuperAge podcast to give us some clarity around the topic. Jim Howard, the President and CEO of Readout Health, has helped to create an innovative biofeedback tool, Biosense, used to measure your ketone levels throughout the day to help with goals for longevity, weight management, or peak performance. He, along with this team at Readout Health, wants to help us regain control of our health through proper nutrition and lower the rates of obesity, type 2 diabetes, heart disease, and more. 

What you will learn in this episode:
- Why using a biofeedback device can promote a better understanding of our health and be used to promote  longevity
- How to know whether you’re in ketosis
- The misconceptions around ketosis, health, and diet
- What intermittent fasting does for the body
- What autophagy is and how it impacts aging
- What Jim’s wellness non-negotiable are

“A good way to look at ketosis, I don’t mean the keto diet I’m talking about ketosis, is that it’s the other side of the metabolic switch, that’s where the damage is undone. We focus on the undoing of the damage that one has done to themselves.” 

“If longevity and healthspan are curious and part of your future plans, I encourage it to be, knowing what your actual body is doing as you enter these zones is critical, as opposed to just guessing.” 

“I was born in 1967 and in this one generation, in 1967 10% of us were obese. 54 years later it’s now at 40%. In one decade it will be 49%.”
