"Empty Stomach and Hunger are not the same thing." - Sadhguru
Sadhguru discusses the right way to perform intermittent fasting, its benefits and how it isn't a new concept. In fact fasting for health has been practiced by a large portion of spiritual practitioners, teachers and gurus for centuries. Unlearn your old broken method of cyclic over eating and under eating. Take control of your appetite and make your energy reservoir (belly/lower abdomen) work for you.
