It's not necessarily telling you if you're trying to reduce different disease risks, so cardiovascular disease or cancer, fill in the blank, whatever disease.

It's not really telling you that.

It's just kind of like, this is the guidelines, right?

So let's talk about the origin of this one-to-two rule.

It really didn't come from direct measurements of health outcomes.

Essentially, it's researchers that calculated for...

Vigorous intensity exercise, you're burning about twice as many calories as you do for moderate intensity exercise.

So it really comes down to energy expenditure, not health outcomes.

Right.

I think that's a really good point because I think people that are more focused on weight loss aren't necessarily the people that are looking at the physical activity guidelines, right?

Those are the people that are counting calories and they're, you know, it's a very different, they're trying to figure out how much exercise they need to do to trim down body recomposition.

Whereas people that are actually looking at the physical activity health guidelines generally in their mind have this concept of,

how much exercise do I need to age better?

That's generally what people are thinking when they're looking at these guidelines.

How much exercise do I need to do to really age better?

And so it's kind of unfair because these guidelines, if they aren't necessarily

indicating how much exercise we need to do or what type of exercise we need to do to really age better, then it's time to change these guidelines.

And I think we're going to talk a lot about that.

But I also wanted to mention, you know, you're talking about these metabolic equivalents with respect to light, moderate or vigorous, you know, intensity, physical activity.

There's some examples for the guidelines that are given.
