First of all it kinda puts you in this “survival” state where while not feeling hungry per say, you’re on high alert and can concentrate like crazy.
And after you finish you feel rejuvenated and excited. Amazing experience and can’t recommend it enough. Done it several times already (4 days fasts) and still having the same initial effect.
After listening through all of the science in Lifespan (the book and the podcast) have started the “only eat in the evening” routine. Like I skip breakfast and lunch.
Still in my first week so its kinda hard, but after another week or two my glucose levels are supposed to stabilize and I would not be feeling the pangs of hunger and highs and lows of sugar spikes after a meal and brain fog after the insulin response has sucked all of the sugar from my blood (and brain).
Its that what I’m really after - steady brain performance throughout the whole day. Will see if I adapt and that actually happens!
