What if I feel extremely hungry between the fast?
Try not to break your fast. You may increase your juice intake. If you are doing a juice fast, switch to a smoothie fast. In case the hunger is still intolerable, you can have a soup. You can learn how to make soups here - https://youtu.be/RgKSQNgHAWk
It's important to know that this hunger is temporary, of a brief duration and rarely severe. At that time, we have to learn to tolerate hunger & remember that this is all just the toxic filth making it’s way out of the body. After a few minutes, hours or days, hunger will disappear.
