We should have an option to not have a food break a fast if it has 0 carbs and has 0 grams of protein for example, I have a Braggs Apple Cider Vinegar, Lemon Juice, and Cayenne Pepper drink which breaks my fast. Also Bulletproof Coffee should not break a fast.
This might be tricky - it depends on what kind of fasting you’re doing - hardcore water only, fat fasting etc. A bit of lemon juice will have a bit of carbs btw ;)
