Welcome to the MyBuddyGreen podcast. I'm Jason Wackib, founder and co-CEO of MyBuddyGreen and your host.

Mark Sissen is a New York Times bestselling author and the founder of one of my favorite brands,

Primal Kitchen. Mark's also 67 years old and by the way looks amazing and he's a true pioneer

in the wellness world so it's going to be great to hear his perspective on some of the latest trends

we're seeing. And talk about all things intermittent fasting which by the way Mark doesn't like that

term as he prefers intermittent kneading. I kind of like that too. Mark's a great guy and it's

an honor to have him back on the show. One of the true pioneers in wellness, the one and only,

whatever energy substrate is called upon or available at the time. So the body is great at

burning carbohydrates. We know that we carbs at every meal must many of us do over the years.

And the body in many cases is so good at burning carbs. It never gets to the point where it needs

to burn fat. We fuel it so often throughout the day. And yet we have this ability to burn fat,
