Other interventions that are less well understood but are also actually quite interesting that we will discuss in depth later, things like nutraceuticals, vitamins, minerals, phytochemicals have been shown to alter fiber type in extreme concentrations.

Now, whether or not small changes in your diet, say how much –

carbohydrates or protein you're eating or any supplementation can actually reach concentrations high enough to alter fiber type is yet to be determined.

I'm not really aware of any research showing that, but certainly we have seen that in many models, again, where we can give them non-physiological doses.

But even stuff as well as hyperbaric or extensive oxygen concentrations, alterations in CO2 intake, and things like that have also, again, mostly in animal models, shown to alter fiber type.

So whether or not this actually happens in a normal human circumstance is not as relevant right now, but it's just highlighting the concept of how responsive this muscle is to everything you're doing in your life.

I'd like to take a quick break and thank our sponsors.

Today's episode is brought to you by David.

David makes protein bars unlike anything I've ever encountered.

They have an amazing 28 grams of protein, only 150 calories and zero grams of sugar.

That's right, 28 grams of protein and 75% of its calories come from protein.

This is 50% higher than the next closest protein bar.

Honestly, it's the best tasting protein bar I've ever had in my life by a mile.

Now, I don't usually talk about products before their launch, but these bars by David represent a meaningful breakthrough in both macronutrients and taste.

And when you guys try it, you will know what I mean.

After lots of research and development, these David protein bars are releasing to the public in September of 2024.

The macronutrients, one more time, are 28 grams of protein, 150 calories, and zero grams of sugar.

And they do this with excellent ingredients.

If you're interested in trying these bars for yourself, you can go to davidprotein.com slash perform to purchase, if possible,

or be notified when they're available.
