What a difference no carbs make

I'm trying out "periodised eating". This is pretty simple, just eat for the workout ahead.

So if a hard workout is planned lots of carbs, if an easy one little.

Past couple of days I've also tried modifying this with an amended form of intermittent fasting. This is a 3 day block when following a hard morning workout I will aim to get net calories consumed (base metabolism + calories burned during workout - calories eaten) well below 1000.

So far this has worked well. I don't feel especially tired, to the contrary I have been able to complete LSD workout well and feel sharp.
