Does toothpaste break the fast when time-restricting your eating?

[Rhonda]: You know, a lot of people just really…they
want to do time-restricted eating and they
want to do it right.
[Satchin]: Yeah.
[Rhonda]: And so, you know, some of these
questions can be a little silly, but it just
shows how people are thinking.
Like, for example, does toothpaste start the
clock?
[Satchin]: If they’re not swallowing.
[Rhonda]: So if you’re not swallowing it,
probably not starting the clock.
[Satchin]: Yeah.
Yeah.
It’s not starting, it’s actually resetting
the clock.
[Rhonda]: Resetting.
[Satchin]: So I think we have to also think
of time-restricted feeding, although we came
from a circadian clock lab.
So that’s why we always get connected with
circadian with circadian clock.
But time-restricted eating has also feeding,
fasting, that whole physiology type to it.
So the other way to ask the question is, “Does
brushing your teeth or mouthwash break the
traditional definition of fasting?”
And definitely it’s not breaking that, it’s
not putting food in your stomach so that the
stomach will start processing it and insulin
starts going up slightly and blood glucose
going up.
So in that way we ought to keep in mind that
we’re bringing that definition back once in
a while.
No, it does not break that fast.
