As for macros and specific food components, the data is a little bit mixed.

Certainly what we know is that if you're eating a diet that is high in sugar and low in protein, your sleep is worse.

Why would that be the case?

Well, one of the reasons that we think is that if you onboard sugar, it can be somewhat metabolically active.

And when it becomes metabolically active, it can increase your body temperature, your core body temperature, even just very subtly.

But that's enough to disrupt your sleep, as we spoke about with temperature.

But I think in terms of...

Really, what would be the ideal macronutrient and even micronutrient dietary recommendation that I would have for you?

I don't think we have enough data yet above and beyond that statement.

Yeah.

Yeah, there is some data on that with the carbohydrate intake in the evening.

And of course, that tryptophan and that carbohydrate intake will contain the precursor ingredients to something else that we've spoken about, which is melatonin.

And so that may actually help healthily boost that melatonin signal.

And there's a little bit of data on that to support it too.

We also did a study where we were looking at night to night to night sleep and carbohydrate intake the next day.

And it did seem to support what you're describing in terms of some of the carbohydrate benefits.

We also found a strange result that was almost the opposite prediction that we made.

Carbohydrate intake in the morning to equally help people wake up.

And we were a little bit uncertain as to why, but we're going to go into more detail.

The reason that you mentioned the suggestion of not to take on carbs in the evening is in part based on the evidence that your body's ability to dispose of sugar, and obviously when you're eating carbohydrate, you can have a higher...
