If I understand it correctly, the goal of intermittent fasting is to keep your body in ketosis so hormones, pro and antibiotics, statins, and antidepressants should be okay. Make sure that you get enough CoQ10 when taking your Nystatin. That stuff does a number on your cardiovascular system!
Not entirely. What DA has done is he created his brand of IF. In practical terms it's simply ketosis, not IF. Fats don't break ketosis, carbs and/or excessive protein does. IF means fasting (no food at all) for 12-16 h/day continuously and then eating in a limited time window. Sorry for nitpicking. 'BP fasting' is a marketing term in my book.
