We are being bombarded with disrupting chemicals. A lot of them, they're in our products.

**Steven Bartlett** (0:05)
Okay, let's go to my kitchen. Come with me. So this is my fridge.

**Dr Rhonda Patrick** (0:09)
So the first thing I notice is this, because that's like the worst.

**Steven Bartlett** (0:11)
Can I get a bin bag?

**Dr Rhonda Patrick** (0:14)
This is made from recycled electronics.

**Steven Bartlett** (0:17)
What about this?

**Dr Rhonda Patrick** (0:18)
This is a problem also.

**Steven Bartlett** (0:21)
And this?

**Dr Rhonda Patrick** (0:22)
Ding, ding, ding, this is great.

**Steven Bartlett** (0:23)
I'm going to do utensils next.

**Dr Rhonda Patrick** (0:24)
Heating it up, the plastic, it's getting into your food.

**Steven Bartlett** (0:27)
What about a receipt?

**Dr Rhonda Patrick** (0:28)
That's bad. It's covered with BPA and study in adolescent boys. Show that it was associated with a 50% reduction in testosterone. And then this is one that people often miss.

**Steven Bartlett** (0:39)
Oh, f***. The biomedical scientist and anti-aging doctor, Rhonda Patrick, is back.

**SPEAKER_3** (0:44)
This time she's talking about health optimization, maintaining peak performance, and the environmental toxins disrupting your body.

**Steven Bartlett** (0:50)
Dr. Rhonda Patrick, let's talk about something that I've never heard of before. Peak span. What the hell is peak span?

**Dr Rhonda Patrick** (0:56)
So, it's essentially being within 90% of your peak function. For example, muscle mass, bone density, that kind of peaks around 25 years old, and then they kind of steadily start to decline.

**Steven Bartlett** (1:07)
You're joking.

**Dr Rhonda Patrick** (1:08)
And the same goes for cognitive function.

**Steven Bartlett** (1:10)
So, I'm on the way down.

**Dr Rhonda Patrick** (1:11)
Yeah, and I'm definitely on the way down, but we can do things in our life to help maintain that peak span. Like, if you exercise five hours a week, do some high intensity interval training in there, and you can reverse heart aging by 20 years. And then sleep, very, very important for preventing your immune system from aging rapidly. And then, another thing that you can do that's really important for brain aging is, and this is associated with a rapid decrease in Alzheimer's disease risk, but what I really want to talk about is intermittent fasting, azembic supplements, and being sedentary.

**Steven Bartlett** (1:39)
So, I want to talk about all of that, but we've got to talk about this in my hands at the moment.

**Dr Rhonda Patrick** (1:43)
So, if you have this, it's going to double your risk of early mortality.

**Steven Bartlett** (1:46)
Double your risk?

**Dr Rhonda Patrick** (1:47)
Double.

**Steven Bartlett** (1:47)

Dr. Rhonda Patrick, I am fascinated by so many of the things that you talked about, and they're front of mind for me at the moment, because I'm a 33-year-old man. And I know from doing this podcast and looking at graphs like this one, which we'll talk about today, which I don't think most people have ever seen in their lives, that this is the age where things might start changing direction from here on over the next decade. And there's things I can do to set myself up now, if I listen to your advice, for the remaining decades of my life to be remarkably different. I'm playing with this in my hands at the moment. It's, for anyone that can't see, you should probably look at the screen right now. It's a yellow blob of squidgy, slightly disgusting material. What is this? And why does this matter?

**Dr Rhonda Patrick** (3:14)
So, this represents visceral fat. It's something that most people haven't heard of. Many people have heard of fat. They know fat is bad. But they don't realize there are different kinds of fat. There is visceral fat. And this is the kind of fat that you can't really pinch. Adipose tissue kind of fat, right? I mean, if you opened up your body, you could pinch it because it's deep, deep within your body. It's often referred to as belly fat. And it's surrounding your organs, like your liver, your kidney, you know, your intestines. This is a very deep belly fat. And it's very different from subcutaneous fat. You can actually be lean, but have a high amount of visceral fat. We call these metabolically unhealthy people. So visceral fat, you mentioned you're 33 The average 33-year-old male has how much visceral fat?
