Can You Survive on Only Meat? One Man’s 12-Month Isolation Diet Says Yes

13 Carnivore Diet

What happens when you eat nothing but meat for a year?

No vegetables. No fruit. No cheats. No “balanced plate.”
Just red meat, salt, water, and sheer determination.

That’s exactly what 38-year-old Mark Jensen from Montana set out to test—voluntarily isolating himself in a remote cabin with one mission: survive on nothing but animal products for 12 straight months.

The results? They’re blowing minds—and nutritionists are scrambling for answers.

13 Carnivore Diet

365 Days. Zero Plants. All Meat.

Mark stocked his deep freezer with grass-fed beef, lamb, liver, eggs, raw dairy, and a few animal-based staples like tallow and bone broth. He took zero supplements. No multivitamins. No greens powder. No “emergency carbs.”

His rules were simple:

  • No plants whatsoever
  • Only water, bone broth, or raw milk to drink
  • Daily journal entries and monthly lab tests

And get this: by month 3, he says his energy was off the charts.


His Blood Work Shocked the Doctors

Before starting, Mark’s doctor warned him about “missing nutrients,” “cholesterol spikes,” and “heart disease risk.”

But the exact opposite happened.

✅ Blood pressure dropped from 138/89 to 118/74
✅ HDL (good cholesterol) went up, triglycerides went way down
✅ Inflammatory markers? Nearly undetectable
✅ Insulin sensitivity skyrocketed
✅ He dropped 27 pounds of fat and gained visible muscle, all without exercise

Oh—and he hasn’t been sick once in over a year.


The Mental Changes Were Even Wilder

Mark says his mental clarity hit a level he “didn’t even know was possible.”

“It’s like I was living in fog before. No crashes. No anxiety. I don’t even crave junk anymore.”

He also claims:

  • Zero digestive issues
  • Better sleep
  • No more joint pain (he had early arthritis signs before the experiment)

“But What About Fiber and Vitamins?”

That’s the part that’s really frying people’s circuits.

Conventional nutrition says you need fiber, you need plants, you need variety.

But ancestral health experts argue otherwise: humans evolved eating primarily meat, with organ meats providing everything the body requires.

Liver alone, for example, contains:

  • Vitamin A
  • Iron
  • B12
  • Zinc
  • Copper
  • CoQ10

Even vitamin C can be found in small amounts in raw meat and fresh organ tissue.


The Mainstream Is… Not Ready for This

Unsurprisingly, the mainstream health world is losing its mind.

Some call Mark’s results a “fluke,” others accuse him of faking his labs, and some flat-out refuse to believe he didn’t suffer scurvy or some deficiency.

But for Mark, the numbers—and his life—speak louder than the critics.


Would You Try It?

Mark isn’t recommending everyone drop everything and become a carnivore. But he is challenging people to ask this:

If one man can thrive on only meat for a full year… what does that say about how we’ve been eating?
