Would using this in water be considered breaking the fast? Does it cause an insulin spike?
It depends on your goals really. If it’s weight loss then you’re fine and if it’s autophagy then you should test your blood sugar to see if you see any response before, 30 mins in and at 2hrs. If it affects you you’ll see it. I know some people are purists but I think if it keeps you fasting and your body can handle it then you do you. Also, during a fast you may experience spikes from stored sugars being burned when fat cells breakdown anyways. Especially if you’re insulin resistant. steps off soapbox lol I hope that was helpful and not too much 😅
