Spliff
Godzilla got busy.
That said, wouldn't the PSMF meals kill the increased insulin sensitivity during the fast? Seems like it would have to be a complete start/stop to get the desired responses.
Nah.
Low cal + low carb (none in this case ) = lack of insulin = heightened sensitivity. The leaner you are the better. Increased sensitivity from fasting isn't designated to muscle only though. The workout will play the biggest partitioning factor along with the diet.
Don't know if the small bits of psmf feeding would effect the other benefits of fasting though. Again, it's just an option.
