I wake up at 4 AM. should I keep hungry till 9 AM?

Yes, we recommend you do not consume anything between 4 AM and 9 AM. Take your first juice at 9 AM. 

Our digestion is very weak in the early morning hours. Our praanshakti is fully engaged in healing during that time and it is best to leave the stomach empty. If we eat something, praanshakti will get shifted towards digestion and leave healing.

If you feel thirsty, you can drink small sips of water. But avoid having juice till 9 AM.
