I’m on day 4 of a 5 day water fast and have about 20 more hours to go to complete this 5 day fast. I feel fine, but I do have low energy. The only thing I have consumed is a 2 cups of black coffee (total), 3 cups of green tea (total) and about 3 liters of water each day. I also take at least a teaspoon of pink himalayan salt and at least a tablespoon of apple cidar vinegar. I had trouble sleeping and day 2 and 3 and did have heartburn so I took some extra apple cider vinegar which helped.
My nurse friend said my hemoglobin is getting dangerously low at 8.8 g/dL as shown in the screenshot below. My ketones are at 6.2. Can I finish the fast or should I eat some bone broth tonight?
