@fastingblog: What does and what doesn’t break a fast? Water, coffee and tea provided it doesn’t contain any sugar or milk will not break your fast. Fat might not break your fast, depending on when was your last meal, what you ate etc. It’s difficult to say unless you have a glucose monitor. Most definitely you should be avoiding sugars and carbohydrates as they will break your fast. Credit to Andrew Huberman for a great, informative video. #fasting #fastingforhealth #andrewhuberman
