Interesting presentation. Nevertheless we have @empiricalcycling Kolie Moore here in another thread with this:
I don’t know if this point was in that episode, but my understanding is that what you eat and what substrate you use for aerobic metabolism during exercise does not alter the underlying aerobic adaptation in any fundamental way. No exceptions. The mechanisms of aerobic adaptive signaling DGAF.
With the exception of short easy recovery spins, I think fasted rides are useless and never suggest anyone restrict energy intake even at the start of rides. Diet manipulation is method that is used sometimes but has a lot of practical drawbacks that make it rare to pull out of the toolbox, since odds it doesn’t work or fully backfires are fairly high. I think you likely heard me discussing this method on another podcast, but restricting food to increase fat burning doesn’t sound like something I’d advocate.
You may be confusing that with my suggestion to always start endurance rides easier because lipolysis takes time to fully make blood borne FFAs available so you end up dipping into glycogen stores too much early on, which often becomes a positive split ride that feels awful at the end vs a negative split ride that feels great later on.
@empiricalcycling Any thoughts on the presentation above “IS-PM05 - High-carbohydrate or high-fat diets for optimizing training adaptation and performance?”?
My gut feeling says that it was all discussed somewhere in this forum already and here we circle again…
