I just posted in another thread how multivitamins are the only pill that give me gut issues and nausea.I suggest a 65 hour fast. stop eating at 7pm and break at noon on day 3. Then you have 7 hours to refeed and decided if you want to roll into another fast. A 65 will break you of fear of not eating for a full complete 2 consecutive days, but it’s not overly challenging. Go to a tdee calculator online and just eat slightly below what’s recommended for calories. With 65s I can consume all foods fine. Unless you love soup, I suggest eat what you love that is health conscious.
