It just means the curve is shaped that way.

And so most things in biology work that way.

They're not positive second derivatives where the more you do, the better it gets and the rate at which it gets better goes up.

That's very rare.

So what is your gestalt on

the optimal zone based on all of the above?

Too little will kill you, too much will kill you.

And that's actually more common in biology, right?

So too much thyroid hormone, too little thyroid hormone, a very bad thing.

Too few calories, too many calories.

That's right.

I mean, sometimes, David, I think it's easier to flip it and just say, why don't we just identify all the people who don't benefit from a higher amount of protein than the RDA?

Because I worry that when we start to carve out a bunch of categories and say, if you're in one of these categories, you should be consuming more, you're always going to kind of miss something or someone might not identify.

So for example, you've used the term bodybuilder.

Most people would never identify themselves as a bodybuilder because when they think bodybuilder, they think of

the caricature type bodybuilder we see on a magazine cover when you're at the airport that doesn't actually look anything like what you want to look like.

But the truth of the matter is, it's hard for me to imagine, I don't know that I can think of one of my patients, let me just start with that as a sample size, one of my patients who doesn't need to, at a minimum, work hard to maintaining their muscle mass.

And many of my patients are working hard to add muscle mass.

And so what differentiates them from a bodybuilder?

The difference is the bodybuilder, of course, has the benefit of using super physiologic doses of androgens, consuming, basically training all day and doing nothing but optimizing around that.
