A friend of mine says to me, Derek, you know your heaviest at night before you go to bed and lightest in the morning when you wake up.

Okay, but that doesn't really seem to make sense.

Of course it does overnight, you're not eating anything for like, eight hours, but you're still burning calories.

So, of course, you'll be lightest in the morning.

But where is the mass going like how you actually losing particles?

You can't argue with me.

I've weighed myself a night and the next morning, and I know it's true.

Is that after you into the toilet?

No, I told you that has nothing to do with it.

What do you have to disagree with everything that anyone says?

You just like arguing.

It's not that I like arguing.

It's just that your statement seems implausible.

I need some kind of mechanism that would explain how you could be heaviest at night and then lightest by the morning.

Why don't you google it?

Okay, so I googled it, and the results were a little bit disturbing.

I'll be 3 to £5 heavier during the nighttime hours, and when I wake up the next morning.

I'm back down £5 less.

I usually wear myself in the morning.

I'm anywhere from 3 to £5 lighter.

Odd.

An empty body weighs less than a full one.

The force of gravity also can weigh a person down.

Really?

Internet.

This is what we're coming to you.

But these are just people posting on forms.

Maybe people out on the street are different.

So I'm gonna go find some people in Perth and see what they say.

Or what time a day do you weigh the most?

What do you reckon?

That's was evening?

Told me just for you.

Yeah, you, Linus, In the morning when you wake up So your lightest when you first get out of bed.

So obviously you keep on eating and drinking during the day because of the sort of people that way, myself every single morning of my life.

And always always lie.

Sister, when you're the lightest first thing in the wake up just right when you wake up, Yeah.

You hop out of bed.

Yeah.

You were a light man.

Yes, of course.

The best way to settle this is with an experiment.

So every night before I go to bed, I will weigh myself.

And in the morning before I go to the bathroom, I will weigh myself again.

Now, in any scientific experiment, it's pretty important to control your variables.

So every time I go for my Weighing, I'm wearing these exact clothes.

I know.

Pretty snazzy, right?

The hotel staff here have graciously allowed me to use their scale.

But they told me I can't take it to my room.

So I need to do the weigh ins at the concierge.

I'm going down for my first weigh in Sunday night.

We'll see what my weight is right now.

At 1:17 a.m. Russ.

So 72.10 kilos.

Where does the mass go while you're sleeping like, how do you lose weight while you're sleeping?

I think it evaporates.

She sweats a lot, digesting it all.

So it's kind of compressed out.

It's true anyway.

Burning.

Are we burning it?

Using it up?

Whatever carbohydrates.

Okay, so where does the matter actually go?

Where does the way actually go?

Transferred as energy that your body uses Says you don't like science stuff like a TV.

Are you saying that we're converting matter into energy.

Yes, that's one way of Is that what you have today?

Uses up the matter?

Yeah.

So you're You just matter is disappearing from inside.

That's my question.

Everything you put into you doesn't come here at the other end as well, so you gotta use it.

Where does that come out?

What uses parts of it?

Thio sustain you and let you live?

It doesn't.

It doesn't come out of you, all of this.

It's, uh, Monday morning.

I'm just gonna I need to go to the bathroom.

So before I do that, I'm gonna go down for my way in.

Last night, I weighed 72.1 kilograms.

Let's see what away in the morning.

71.9 ST.

9 to 5 kilograms.

I'm not really surprised.

My masses only changed by about 150 grams.

That doesn't really surprise me, but, um, yeah, I don't think it's backing up my friend's theory.

So we'll have to do this a few more times to make sure that these results of Allah difference of bounds to five kilos of 250 grand's 72.5 kilograms.

That's a loss of about 300 grands.

So it looks like every night you lose about 250 grams, just pretty similar to the amount that I've been leaving every day this week.

So how do you actually lose weight as you sleep well every night this week, I seemed to lose about 250 grams.

I think about 150 grams of that was water loss through sweating and breathing out water vapor.

So where's the other 100 grams going?

Well, every time you breathe in your breathing about 500 milliliters of air.

But on Lee, about 1/5 of that, his oxygen and 3/4 of that oxygen.

You'll just breathe out again, but 1/4 of it gets replaced with carbon dioxide.

Now carbon dioxide compared to oxygen has the extra mass of carbon on every molecule, and the massive carbon released in every breath is about 1/100 of a grand.

I know that doesn't sound like a lot, but if you added up 16 breaths a minute over eight hours, it adds up to about 100 grams.

Every time you breathe out, you're losing weight because they come off never heard of that before then?

I don't know.

I mean, people don't talk about it.

People don't think about it because I think a lot of people think that matter can be converted to energy, that you can take stuff.

And then it goes away somehow in the metabolic process in that energy process.

My point is the atoms are still that of matter is still there.

You need to get rid of it somehow, and some of it is is breathe.

So people were right when they said that you were burning calories, and that's causing you to become lighter.

They just didn't think about the exhaust, the water vapor and the carbon dioxide that you breathe out.

So it may be the case that your heaviest at night and lightest in the morning.

But I think the real truth of the matter is your heaviest after your biggest male and lightest after you've gone to the bathroom.

It's after lunch on Thursday, so let's see what difference a big meal makes.

I was 71.1 kilograms.

I'm now 72.55 nearly added a kilo and 1/2.

My lunch was nearly a kilo or so.

This morning, when I woke up, I was 72.1 kilograms.

But now I've gone to the bathroom, so I'd like to see what difference that makes 70.6 kilograms.

That is a lot of mass that I've lost.

What is that like 1.5 kilos, 1.5 kilos?

That's a lot of mass.
