I eat a high fat, low non-fibrous carb, moderate protein diet since reading the Rosedale Diet and Primal Body Primal Mind. I have been doing this for some time - years.
I also exercise daily, upon waking, fasted. Sometimes I do high intensity intervals, some days weights, but something every day for sure. I also walk a lot.
I keep seeing here that folks are recommending starch post workout to attenuate the cortisol response. I am at odds with this recommendation. It seems that for longevity purposes, spiking insulin (and leptin?) in order to lower cortisol is just fighting fire with fire (dousing the post workout cortisol with a insulin spike).
So, my question: Is intense exercise really optimal for longevity? If not, what kind of exercise is best so one can continue high fat low carb without the cortisol issues?
EDIT - I'm interested in discussing whether the act of exercising in such a way that "necessitates" carb refeeds is optimal.
