Title, not sure if this has been posted before but reddits search function is notoriously helpful.. Planning on starting IF this week and I prefer these to black coffee, purely for the easy delivery. It’s got no sugars or calories but I know that’s not all that goes into it. Thanks a bunch.
Depends on how strict you want to be. It does contain sucralose, which is an artificial sweetener that studies have shown to increase insulin production. The point of fasting is to lower your insulin levels so your body burns fat stores for fuel instead of glucose. Potentially spiking your insulin levels with artificial sweeteners sort of defeats the point.
But on the opposite side, there’s not hard, proven science on how much artificial sweeteners actually impact your insulin levels. So it’s more if you’re not super strict about your fast and want to try it, go for it and see how it works for you.
