My understanding is that there is a new calculation method for converting average serum glucose to a1c called GMI. I believe the calculation you use to convert glucose to a1c is the other calculation method. My understanding is the GMI has been derived from patients with diabetes and perhaps the other calculation method is more relevant for your patients without diabetes who are using CGM. But I would appreciate it if you could give us some more info and context on the conversion you use and why.
Following your recent video on overtraining, I think your subscribers (and probably future patients) would benefit significantly from a podcast discussion with Dr Doug McGuff or Drew Baye. Learning to access and fatigue type 2 muscle fibre safely and effectively is essential in the 'longevity' arena. Ego lifting and number chasing are not required in the weight room.
Peter likes to target the transition between zone 2 and 3. This makes sense for an endurance athlete, who needs to be predominantly in zone 2 during their competitions, in order to perform over long distances. For longevity / healthspan, however, or more specifically for mitochondrial capacity, why wouldn't we target moving the fat oxidation peak further to the right? Wouldn't doing so imply training at or near that peak, which resides in Zone 3?
