Water fasting triggers ketosis by day 1 or 2, while fasting-mimicking diets reach it by day 2. Both require low carbs and low protein to trigger autophagy, which may matter more than ketosis itself for fasting's health benefits.

What's the switchover usually with a regular water fast versus a fasting mimicking fast.
So water only will typically start seeing that around the 12 hour mark. We have gotten rid of all of our glycogen stores and our free sugars that are floating around, and that's when the body will start shifting over into ketosis. And then it's a gradual increase. It usually, you're usually in full ketosis by the end of day one or day two, at which point, you know, as long as you don't consume more glucose or sugar, you will will just keep gradually increasing over time. Now, with fasting mimicking, what we see is that day one is our gradual transition into ketosis, with day two being when we start getting into that functional ketosis. So another important thing to note is that yes, ketosis is absolutely a part of the benefits of fasting mimicking and fasting, but is not the only one. Right. We also, and maybe more importantly, need to get into autophagy. And you can get into ketosis and never get into autophagy because ketosis is just about low carbohydrates, it's not about low protein, whereas fasting is about both of those things being low. And so it actually allows you to get even more benefits.
