I can fast a whole day due to health reasons (such as borderline diabetes or hypoglycemia). How should I handle the fast day?
We would recommend that you not fast the entire day. You could begin by fasting one meal and only drinking liquids during that meal, and then as time progresses and things change you could work your way into fasting two meals while closely monitoring your physical condition. And then you could, over time, move to a full day as long as your health doesn’t deteriorate. Keep a close eye on it and make changes as needed. The objective is to give something up, and then seek the Lord during that time with the energy that you would have spent on the other.
