Episode overview:

Chiel Poffe is a Postdoctoral researcher at KU Leven. His areas of focus are energy metabolism and ketones.

Episode highlights:

(32:56) Practical ketone use: best during high-intensity training, 25g after exercise and before sleep, individual variance, potential improved sleep, muscle recovery, cognitive benefits, cost

(39:38) Ultramarathon study results: complications with investigating performance, reaction time test, no cognitive decline in ketone groups, ketone increase dopamine levels, mechanistic speculation

(45:19) Ketones aid cognition in extreme circumstances: revisiting study design, parallels to the overtraining study, ketones inhibit cognitive decline rather than improving cognition, support from initial ketone research
