Is plant protein high-quality protein? Are vegans better off?

You can make a lot of claims, but what are the metrics being used to determine what is "high-quality" protein? Which biomarkers?

Track what really matters. Super-healthy animal protein with fermented foods lowers the important biomarkers.

Your brand-new coffee grinder smells like an electrical fire when you open the box. That smell is residual manufacturing oil, chemical coatings, and industrial residue sitting on every surface, ready to be absorbed by your coffee beans and put into your body.

You can't put soapy water inside of a grinder, so what do you do?

Take the cheapest coffee beans you have, the ones you would never drink, and run 5 to 10 loads through the grinder. They'll absorb the oils and residue. For coffee pots, flush with water and white distilled vinegar, and do it multiple times.

Never use a new food appliance without cleaning it first.

I was wrong about GLP-1 drugs.

Not about the target. GLP-1 is one of the most powerful metabolic signals your body produces.

I was wrong to dismiss it because pharma got there first.

Here is what I missed (and what most doctors still miss):

Your body already makes perfect GLP-1.

No side effects. No muscle loss. No exorbitant monthly price. Your cells produce it when your microbiome is working and your
diet is right.

The synthetic version of GLP-1? It cannot distinguish between the fat that is killing you and the tissue that is protecting you. Up to 40% of what people lose on these drugs is muscle—including heart muscle! That's collateral damage disguised as progress.

Kefir is a superfood. Optimize your microbiome.

Buying organic coffee is a waste of time...if you don't clean out that brand-new coffee grinder.

Manufacturing residue and industrial chemicals still remain. What do you think causes that "new appliance" smell?

Get it clean by running 5-10 loads of cheap coffee through the grinder. That way, you don't ruin your good coffee, and you aren't poisoning yourself with other chemicals.

Arguing online about whether carnivore or vegan is the superior diet while having no MRI of your own insides is the nutritional equivalent of backseat driving blindfolded.

Esophageal cancer has a 90% five-year mortality. Its precursor—Barrett's esophagus—is often completely silent. No heartburn. No symptoms at all. In some patients, the symptoms actually disappear as the disease progresses because chronic acid exposure destroys the esophageal nerves.

But the fat surrounding your esophagus is visible on an MRI years before Barrett's develops. Visceral fat represents a 6x increased risk

These markers show on scans that are already being ordered, but no one is paying attention. No one is reporting it.

I had Barrett's myself, with precancerous lesions, getting scoped every three months, waiting for cancer. I reversed it by eliminating visceral fat. You can do the same.

A man who'd been vegan for 5 years thought he was healthy. His MRI told a different story.

Small muscles. Visceral fat packed around his organs. Inflammatory fat surrounding his heart. Marbled fat through both legs. Then I compared his scan to someone 74 years old.

And the 74-year-old looked better. Cleaner legs. No marbling. Eleven years older and in much better shape where it counts.

I'm not here to indict veganism on one scan. But I am here to tell you: if you are making dietary changes without imaging, you are guessing. And guessing with the only body you'll ever own is a bet most people cannot afford to lose.

Get a baseline MRI scan. Make your changes. Rescan. That's the only way to know for sure.
