Podcast – Shattering Pre- and Post-Workout Fueling Myths with Ben Greenfield

Description: Between the latest online fads and the crazy media headlines, it’s easier than ever to get confused about your health. If you want to make better decisions about your health today so you can feel better and live longer, you’ve come to the right place.


On this episode we’re looking at the best way to fuel your body before a workout and the most effective way to refuel after your workout is done. You’ve probably heard mixed messages about the optimal time of day for consuming the bulk of your calories, whether or not you should graze or snack throughout the day, and whether overnight fasting has any real benefit.


I’m joined today by Ben Greenfield, former bodybuilder and Ironman triathlete, coach and author. He has solid information for every kind of person, from the non-athlete that is looking for ways to enhance mitochondrial efficiency and fat burning oxidation capacity during the day in order to increase energy levels to the high performing athlete that wants to maximize energy burn during their next Ironman. He shares ways to properly fuel your body before your workout if you have been fasting overnight, the value of a cyclic ketogenic or low carbohydrate diet, and specific methods for ingesting appropriate amounts of fuel. Whether your goal as an athlete is to increase your endurance or as a non-athlete that just wants to muscle gain, lose weight or replenish your energy, you’ll want to hear the specific advice Ben has to help you fuel your performance in the best way possible.

“I don’t prioritize pre- or post-workout nutrition for the non-athlete population. A lot of the advice given is just trickle down advice from professional sports.” — Ben Greenfield


“If you have eaten before a workout there is no need to prioritize post-workout fuel.” — Ben Greenfield


“The fuel that is most useful to your body in a race is not the same fuel that is most beneficial in your day-to-day life.” — Dr. Christianson


“Every time you stop to snack you’re ripping your body out of the state in which it’s tapping into its own source of fuel for energy.” — Ben Greenfield
