Limited but interesting research on (good) effect of low carb diet on AMPK.
"Our data indicate that a relative deficiency in carbohydrate intake or, albeit less likely, a relative excess of fat intake even in the absence of caloric deprivation is sufficient to activate the AMPK-SIRT 1-PGC1α energy-sensing cellular network in human skeletal muscle."
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.
