I know a lady who went 3 months as a breatharian, she spent every waking moment in prayer chanting God's holy names, she preferred Hare Krsna MahaMantra.. It was a phase / test for her. She went back to pure vegetarian prasadam diet.
Their is another yogi in India who eats only once a month and eats only whatever the locals bring him, he consumes everthing thing.
Dr. Gary Young of yound living wased paralyzed and tried to commit suicide by fasting on lemons and water for 220 days, when he realized he could move he big toe, now he is running in marathons and walking in green pastures.
Keep your disbelief to yourself, or cast it aside the choice is yours. and Don't disturb others who are walking the walk.
