I'm guessing you mean this:
H
ow to Lose Weight #8: Avoid Artificial Sweeteners> He drank a Pepsi Max, and checked blood sugar and ketones for 7 hours.
Do we know where he drank that?
The sweetener used varies by country.
> As expected, blood sugar didn't change much at all.
> But, ketones quickly dropped, taking him out of ketosis, and stayed there for several hours.And the first thing I thought of was just what he speculated, that the artificial sweetener provoked an insulin response.
Right now the gold standard for carb effect is blood sugar. I'm wondering if insulin response deserves equal billing.
I've said on WBB that I'm not sure that artificial sweeteners are fooling only the tongue. I've also asked if it's a problem if something provokes an insulin response, but doesn't raise blood sugar. So far, these are unanswered, possibly because nobody knows, or even that it doesn't matter.
> To one who is trying to eat a ketogenic diet (LCHF), that's significant.Well, a keto diet will be LCHF but not all LCHF is keto. However, in most LCHF you will be in keto at least some of the time, unless you're not, and it sounds like a diet pop at bedtime could derail you.
> It indicates to me that 'something' is responding to the sweetener in ways that are undesirable.Usually, it means that the liver is distracted with metabolizing something, like alcohol. I've also asked if sugar alcohols can do this, and haven't found an answer. This might point to an issue with even the WB-approved sweeteners. If they have an insulin effect and/or kick the liver out of keto, consumers need to know so they can decide what, if anything, to do about it.
> I eat a LCHF diet. I don't check ketones, though.You might want to just to verify that you are in keto, then again to see what the diet pop does.
> I also drink a diet soda several times per week.What sweetener?
I only drink water, coffee, wine and more rarely, stevia lemonade or stevia margarita.
Of those, only the water has no material metabolic considerations.
