recently i've been following the grub from the garden, a guy deep into holistic health and bretharianism.
in my opinion he just is the gold in terms of fasting, i want to share two of his pillars:
-conscous breathing and breathwork does wonders to control hunger
the second outside the frames of mosts probably
-Urine is Medicine(the best), witch helped me with my fasts with almost no hunger... Amazing
do your research and sorry for the english, i'm italian
