Today, I’m talking with Jeff Rothschild about his recently published study looking at fed vs. fasted cardio. Does protein change which fuels you use – fats or carbs? Does eating beforehand make a difference? Listen in as he joins me all the way from New Zealand!

We discuss:

  • Jeff’s background as a dietician working with a wide range of athletes and his current role at Auckland University of Technology – Sports Performance Research Institute of New Zealand (SPRINZ)
  • Research began with a survey looking at what endurance athletes eat before exercise – if anything
  • Results of research testing performance elements with cyclists not eating or eating either a carbohydrate or protein meal
  • Hunger post-exercise
  • Intra-exercise calories or electrolytes
  • The type of fat you’re burning when you’re exercising
  • Discussion of Mark Fell study: “Carbohydrate improves exercise capacity but does not affect subcellular lipid droplet morphology, AMPK and p53 signaling in human skeletal muscle”
  • How do you burn more fat?
  • When to avoid fasted training
