2.5 million years ago we first began to eat
meat.

Prior to that our ancestors ate a vegan diet of berries and flowers and only when early

hominins began to eat more seeds and nuts, therefore taking in higher levels of fat

and less fiber did our bodies begin to adapt to handle meat.

But what would happen if now you ONLY ate
meat?

Without fiber rich foods like lentils, beans,
and broccoli you are going to feel constipated

Not to mention, the simplest way for the body
to make energy is to convert carbohydrates

In the absence of carbs your body will have
to burn fat and break down important proteins.

Creating glucose from protein is known as
gluconeogenesis, and it occurs in the liver,

creating a nitrogen waste that is converted
into urea.

Too much can lead to protein poisoning - which
includes symptoms like nausea, diarrhea, and

It's even been documented if you ate only
a lean meat like rabbit, which has hardly any

fat, you could eat and eat and eat and still
end up wasting away.

Another potential killer could be the lack
of Vitamin C. Humans are one of the few animals

that are not able to synthesize the Vitamin
on their own.

Without easy access to Vitamin C from fruits
and veggies your body will be unable to effectively

create collagen, a structural protein found
in your tendons, ligaments and skin.

This will put you at high risk of scurvy and
cause you to have poor wound healing, rotting

If not treated you would die from infection
or bleeding.

But eating raw meat could be the way around
this.

The cooking of meat degrades most of the Vitamin C, but raw, thick, chewy collagen rich skin

and blubber of whales can take in 36mg of
Vitamin C per 100g serving.

Way more than the 10mg needed to fight off
scurvy.

This brings us to an interesting case: shaped
by low temperatures and a stark environment,

a traditional Inuit diet consisted of what
was hunted and fished with little, if any,

plant food, dairy products, or carbohydrates.

Despite this, cardiac death rates were half
that of other Americans and Canadians.

How can you be healthy on a fatty diet without
any fruits and vegetables?

You can snack on organ meat like liver to
get your recommended Vitamin A, which is vital for

eyes and bones and Vitamin D (for your bones
too). And Oily fish rich in omega-3 fatty

acids will benefit your heart and vascular
system.

Inuit bodies have adapted to manage gluconeogenesis
by having larger livers and increased volumes

A recent genetic study investigated the genome
of Greenland Inuit and found a selection for

variants that create a protective effect against
cholesterol and triglycerides.

So, it is possible to thrive on only meat
but it's important to remember that Northern

communities have relied on animal food out
of circumstance and necessity.

Their high fat diet was intended to keep weight
on for days of hunting, and when food was

insecure, not lose weight like modern low
carb diets.

Unless you are planning on eating raw whale
blubber, organ meat, and have genetics on

your side consider sticking to a balanced
diet of all the major food groups.
