Podcast: Experiments at Long Play: ketones and low carb

Welcome! and Thank you for listening.  Don’t fall off your exercise ball but we are going to talk low carb and keto!

Last week I completed the Long Play 33 with 35 miles- bonus miles as Andy, the race director, would say.  Based on a recently published study on nutrition during endurance events, I decided to decrease my glucose intake and add Ketone IQ shots to the mix.  

I have a history of bonking in the later parts of a race.  Sometimes, it is more like the early part.  My stomach no longer accepts gels, I feel sluggish, and have assumed it was my mental attitude and the need for more fuel.   I figured I was dehydrated leading to a decrease in blood to the gut and inability to digest my intake resulting muscle glycogen depletion.  As soon as I started taking gels, I became dependent on them.  Once, I could not tolerate them, I was headed for low energy and the need to walk or quit.  

My new hypothesis is that it is my brain’s demand for fuel and my bloodstream dip in glucose that causes the bonk.  Wild swings in glucose and insulin followed by a decrease in my ability to burn fat as fuel.  So I tried a few new things this race and had a pleasant surprise. 

I had another pleasant surprise with my follow up lipid and DHA levels.  Certainly, a tell all episode.  

Thanks for listening.
