Fat should never be in your liver, it should never be around your organs, it should never be marbling inside your muscles, it should never be interwoven in your pancreas, around your heart or around your kidneys. Those are the danger zones. And once fat starts to accumulate there, which will happen in any form of excess energy, awful things are going to happen.

And it doesn't matter if you're eating farm-to-table or if you're eating McDonald's. Now, one could argue, If you are eating highly processed foods, it's an easier path to get there. And I agree with that. I think there's reasonable evidence to suggest that The more palatable, the less nutrient-dense, the lower quality the food, the easier it is to overeat.

But we just shouldn't lose sight of that objective, which is you don't want to eat too much. And of course, you don't want to eat too little, although that's less of a problem today. We should acknowledge it's still a problem. I think the second order term is You've got to make sure you're getting enough protein for adequate muscle protein synthesis. I always joke about this and my wife teases me.

You can't walk through the hospital hallway and interact with people in the final years of their life and find anybody saying, I wish I had less muscle mass. So we all have to remember that gravity is working against us as we age, and sarcopenia, which is the loss of muscle mass, osteopenia, the weakening of bones, all of these things are enormous causes of age-related morbidity and mortality.

And so adequate protein intake, in addition to adequate caloric intake, are the two most important pillars. Then you can start to go, okay, Peter, I get that. Now tell me what to do. And then believe it or not, I think we get into a highly variable way that the body works. There are some people who do incredibly well on diets that are very high in carbohydrates.

There are others who do incredibly well on diets that basically omit carbohydrates altogether. I was one of those people, by the way, for three years from 2011 to 2014, I was on what was called a ketogenic diet. So that meant for three years, I think I had carbs once. Literally one day on my wife's birthday, I had three pieces of cake.

And aside from that, the only form of carbohydrates I had was lettuce and some berries. But otherwise, it was all protein and fat. I did very well on that diet. It served me incredibly well. But for some people, it did not. And that's fine. When you start to get into kind of...

Some of the more minutiae that people tend to fixate on, it's a little bit of majoring in the minor and minoring in the major. The evidence gets squishier and squishier. The arguments get more and more mechanistic and less based on actual data. So you can make a plausible argument that maybe you shouldn't eat that type of fat in favor of this type of fat.
