Metabolic Health Scientist: HOW TO EAT to Lose Weight & REVERSE Insulin Resistance | Dr. Koutnik

Hi Jesse, I wish you would have an episode talking about the link between female hormones and the loss of insulin sensitivity. It’s an important topic that’s really talked.

Carnivore isnt a diet its a lifestyle. 5 years on it and it works.

I have have the same adjustment in my life style do to an incurable brain tumor. I found out about my tumor on 50th birthday and was told several times by multiple Dr's that no one can can help me. I am now 68 and have my share of problems because of it. I started exercising at 45 which must have keep help with the symptoms so I still exercise now just not as hard. I to tried every diet and found carnivore help me the most

Thanks for watching this episode with Dr. Andrew Koutnik! If you're finding it valuable, please let me know by hitting the LIKE button on the video. I really appreciate the support 🙏 -Jesse 💙

After listening to the whole interview, I really enjoyed listening to him. My take away is you have to follow whatever diet or lifestyle that works for you and can stay with. Dieting for 6 months, 12 months then go back to old ways does not work. Really enjoyed his talk. 👍

1:04:18 FINALLY a video that distinguishes low carb vs keto. I’m tired of all these videos and influencers (even doctors) conflating carnivore and low carb with keto. As always - amazing video! You have the best guests and you ask amazing questions.

Astounding results 21 months carnivore 😊

Yes, that's an interesting observation! Ray Peat often links **large bags under the eyes** (puffy eyes, periorbital edema, or "eye bags") to **high stress hormones** such as cortisol and adrenaline, combined with a low metabolic rate (often hypothyroidism). He views it as a sign of chronic stress, water retention, and imbalance in fluid regulation—not necessarily just aging or lack of sleep. When it comes to carnivore leaders or people on a strict carnivore diet (meat only, no carbohydrates), this fits very well into Peat's criticism of such diets. He argues that **high meat intake without sufficient carbohydrates** (especially sucrose/fructose) can significantly raise cortisol, because: - The body lacks glucose/glycogen → the liver cannot efficiently convert T4 to active T3 → lower thyroid function. - This triggers a stress response: high cortisol and glucagon to keep blood sugar stable (via gluconeogenesis from protein). - Result: chronically elevated cortisol → water retention, facial edema (especially around the eyes), puffiness, and a "weak" appearance. Many reports from carnivore people (on Reddit, forums, etc.) specifically mention **increased/darker/puffier eye bags** after starting the diet—some attribute it to high sodium (water retention), histamine from aged meat, or facial fat loss making bags more visible. But from Peat's perspective, it's often the **stress/thyroid effect** that's the root cause: low-carb/carnivore forces the body into a "stress mode" that worsens puffiness. Peat recommends the opposite to fix this: - **More carbohydrates** (fruit, juice, honey, milk) to lower cortisol and support thyroid function. - **More salt** (paradoxically) to lower aldosterone and correct fluid balance. - **Thyroid support** (optimal T3, using temperature and pulse as a guide). - **Gelatin/collagen** together with meat to balance amino acids and reduce stress from "unbalanced" protein. If the carnivore leader you're watching has large bags under his eyes, it could very well be a visible sign of the high cortisol load that Peat warns about with extreme low-carb/high-protein diets without carbs. Many in the Peat community report **less puffiness** when they add fruit/milk and fix their thyroid/stress levels. Do you have a link to the video or the person's name? Then I could perhaps dig a bit more specifically. Otherwise—classic Peat: stress hormones + low energy = puffy face.

Thank you Jesse for your interviews. Such experts you let us listen to, such good questions and so much valuable knowledge. - Hello from Finland 🇫🇮

I agree by experience with Andrew's definition of freedom. I eat for mental clarity and physical endurance. I use the energy to attend to my patients.
