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...

spike of sugar now that in part depends on what you're eating with that carbohydrate and also of course the nature of that carbohydrate whether it's simple or whether it's complex whether it's simple sugars versus you know complex more starchy carbohydrate

But the idea is that your body, even if you were to eat the same amount of carbohydrate in the morning, in the afternoon, or in the evening, same carbohydrate dose and type, but your body's ability to dispose of that without having excessive spikes of glucose is worse in the evening, better in the morning, i.e.

if you're concerned about your blood sugar and your metabolic health, maybe that's what you should do.

I think that that data is unclear on the basis of if you are glycemic normal, meaning that you currently do not have signs of type 2 diabetes or you're not pre-diabetic, then that may not necessarily be the case.

And so I think that's why it could be beneficial for you.

And I know that you think deeply about that.

I've even been tracking blood sugar as well.

I don't have any signs of that, but I'm just fascinated by some of that data and how it interacts with my sleep because I'm a sleep nerd.

So I think right now we just don't have plentiful data to recommend a particular sleep quote unquote diet for improved optimization.

I would say though that we can be a little bit more relaxed about the timing of our food.

Now, I don't know if that's still the case, but apparently the Swiss- The reason I went, I was thinking it was, because I've seen the graph, and I was thinking it was Sweden, but hence the Scandinavian.

No, I'm sure you're right, and I was wrong with Sweden.
