Doug McGuff MD | Biochemistry of the Paleo Diet (and slow burn exercise)
A good summary of everything I have learned so far including LCHF, metabolism and slow burn exercise.
The whole video is interesting in parts, but the really interesting part is the science from approx 1hr 2m for about 25mins.
It explains how and why a few mins of slow-burn, muscle failing training works better then an hour of aerobics. Good explanation of cell metabolism too.
The Q&A after that is good too.
