Statements from this episode (29)
Petkas: Fitness must be treated as essential daily hygiene
“Hygiene is the aspect of you will decay or die if you don't do it, right? If you don't brush your teeth, like you're going to have nasty teeth and it's going to break down. Same thing if you don't wash your body, bacteria. I view fitness as the same thing. Whe…”
Petkas strictly limits his gym sessions to 50 minutes maximum
“How long do I spend in the gym? 50 minutes. Five-zero. I am in and out. There's no way I'm spending more than an hour, ever. That's warm-up, workout, cool down, and stretching.”
Petkas: You are never overtraining, you are chronically under-recovering
“Because you're never over-training, you're under-recovering.”
Petkas: Cooked vegetables are often much better tolerated than raw ones
“Not all vegetables are bad for you the way they're prepared sometimes, right? They're better if you're, they're cooked for a lot of people.”
Petkas: High-consequence physical challenges drive accountability and introspection
“With it being of consequence, right, there's accountability to it, so I think it's a little bit more all-encompassing, right? You have to be consistent about your preparation, your training, you have to have a lot of intention behind it as well, and I find tha…”
Sanchez: Tackling hard physical challenges together is rare for modern couples
“I do think that having some component of doing really hard things, not just individually, but together, Is maybe rare for couples these days.”
Petkas: Facing physical challenges reveals a partner's independent resilience
“Like you get to see that your partner can struggle, has struggled, will struggle, and they'll make it through themselves. They might not always need to depend on you either.”
Petkas: Microwaving food denatures nutrients and lowers bioavailability
“We do not use the microwave in our household any longer just because it's shown to denature a lot of the nutrients and make things less bioavailable, right?”
Petkas: Lower back pain is usually caused by weak glutes
“Your hip flex, your lower back is not caused, your back pain is not caused by your back. Most of the time I've found it's caused by weak glutes and too tight of hip flexors.”
Sanchez: Old World European wines have fewer pesticides than US wines
“Typically old world because there's less fuckery happening there than they do in the US with pesticides, et cetera.”
Codie Sanchez: Most Medical and Scientific Studies Are Conducted on Men
“It's just most medicinal scientific studies, as she's taught me, are done on men, not women.”
Sanchez: Intermittent fasting is often inadvisable for women trying to conceive
“And things like intermittent fasting, I didn't even realize aren't great for women in a lot of instances, especially if you're trying to get pregnant, etc.”
Dr. Lyon: Six cups of quinoa equal one small chicken breast
“You would need six cups of quinoa to equal one small chicken breast, and at the end of the day, if you care about numbers, then you have to understand these things are not interchangeable.”
Lyon: US Commodity Whole Food Marketing Budget Is $750 Million
“All of the farmers, all of the producers pool their money together. Their collective marketing budget is seven hundred fifty million. All commodities. This includes beef, this includes chicken, this includes dairy, this includes corn, soy, etc.”

Dr. Lyon: 40% of women over 65 consume below RDA protein levels

Dr. Lyon: Chronic metabolic diseases begin decades earlier in skeletal muscle
“Is all the issues that we are seeing, obesity, diabetes, cardiovascular disease, Alzheimer's, is this all a fat problem? No. It begins in skeletal muscle first. Decades before.”
Dr. Lyon: Skeletal muscle is a currency that cannot be bought
“From a fundamental perspective, muscle is currency. You can't buy, you cannot pay for, and you can't bargain for. It's actually currency you have to earn, and the only way to earn that is by instilling habits and becoming a certain type of person.”
Dr. Lyon: Whole animal protein cannot be fully replaced by supplements
“I mean, because it's not just about the protein. It's about the food matrix. It's about bioavailable iron and zinc, selenium, creatine, carnitine, and serine. You shouldn't need to take a million different supplements. We didn't evolve that way.”
Dr. Lyon: GLP-1 agonists are more effective than bariatric surgery
“These medications are more effective than surgery. There is less downtime.”
Dr. Lyon: Mounjaro is preferable to Ozempic due to fewer side effects
“Ozempic is not my favorite. There's too many side effects. I'm much more interested in Mongerno or Trisepetide.”
Dr. Lyon: GLP-1 muscle loss stems from poor diet, not the drug
“The reason people lose lean tissue on these medications, which is the other big criticism, is because they are not training, and they're not eating dietary protein.”

“The mom creates an epigenetic environment for the child. The healthier and fitter the mother is, the healthier and fitter the child is.”
Dr. Lyon: Peak entrepreneurial highs create maximum vulnerability to vices

Dr. Lyon: Seed oils are irrelevant if you avoid processed foods
“If you're not eating processed foods, you don't have to give a shit about seed oil.”

Sanchez: Eli Lilly and Novo Nordisk could become trillion-dollar stocks
“And I realized that they might actually create the first trillion-dollar drug stocks. So the two companies, Eli Lilly and Novo Nordisk, could be trillion-dollar drug stocks.”
Sanchez: Ozempic drove 41% of Novo Nordisk's record $13.9 billion profit
“Novo is having the highest record profits of all time, 13.9 billion dollars, and Ozempic alone accounted for like 41% of that, which makes it the fourth highest sold drug of all time.”
