Hi everyone, welcome to today's Science vs. Bullshit. I'm going to very quickly do that

really annoying thing where I'm like, did I go live? Because I still can't see where I'm

meant to be looking. Dashboard? Probably not. I still can't really tell. If anyone does come on live, tell me that you're here and then I'll be able to...

Oh, okay, right, I can't see my...

Times, which is strange.

Anyway, right, fine, we're here. We're live.

We have excellent questions.

Let me get them up.

Obviously, if anyone has any live, fire away. Okay, the first one is,

Hi, I was wondering, with your knowledge, thank you, if you could explain, if, okay, if you could

explain, full stop.

If I diet and I just walk as exercise, I will lose weight.

If I diet and I walk and then I lift twice a week, I don't lose weight, I just stay the same.

Yes, I do change shape, but my weight stays the same and I have weight to lose.

Any ideas, I've always done some form of gym or sport or classes regularly and fairly active

job, i.e. I don't sit down. Thank you. So the truth of this is, if you diet and you don't

exercise, you will lose more weight, which a lot of people hear and are like,

what? That sounds insane. Or, okay, well, then I just won't exercise. You're losing more weight

because you're not only losing fat, but you're also losing a bit of lean tissue as well,

of which some of is muscle mass. So it's definitely not a good thing. The other thing I'll say

about this is that you are probably being a little bit impatient to an extent. And then finally,

and I'm just kind of reading between the lines here and realistically, like, for any questions
