Dr. Anthony Chaffee & Dr. Ken Berry on Carnivore

2:48.  We learned just how toxic plants were.   I was taking botany.  I was taking cancer biology and this was how plants defend themselves.  They defend themselves by having defense chemicals that deter animals and insects from eating them. We learned that there were 136 carcinogens just in Brussels sprouts, over 100 in mushrooms, dozens and other vegetables that we eat on a daily basis.  

My professor at the time was very much against eating plants we were quite surprised by this.  But he even said himself that he didn't need salad.  He didn't eat vegetables.  He didn't let his kids eat vegetables, and the plants were trying to kill you.  

3:27.  So I just stopped eating plants.  At that point, I didn't even realize it but I was eating a carnivore diet at the time [yes, a plant-free diet], and I felt absolutely amazing.  My athletic performance just went through the roof.  My mental acuity and sharpness got razor honed, and I just felt amazing.   I ended up slipping off of it because I didn't realize how significant what I was doing was.  That over the last several years I have come across information that says humans have been carnivores for quite a long time and that biologically+ we're most adapted to that or predisposed to that and we don't have these set up defenses against all the plant toxins then we probably used to have millions of years ago.

Get fattier grades of burger meat from the butcher, 70/30, 60/40, even 50/50.  Now that's the ticket.

DR. ANTHONY CHAFFEE: why would your body be working so damn hard to absorb fat if it didn't want the fat?

You got five organs all working in concert just to absorb fat.  

Stomach starts breaking things down.  

Your liver makes bile.

Your gallbladder stores that bile.  

Bile is used to break down and emulsify that fat. 

Pancreas makes lipase and other enzymes to break that down further, and then the bile gets absorbs that with the bile in your small intestine.  

So why would your body be working so damn hard to absorb fat if it didn't want the fat?  If that was bad for you, all it had to do was just turn one of those things off. Just don't make bile.  You're never absorbing fat.  If that were so bad for us, why wouldn't have nature taken care of that?  

DR. ANTHONY CHAFFEE: When you're eating carbs, you are going to breed for and select for the bacteria that rot your teeth

DR. ANTHONY CHAFFEE: Two things that prove that humans were not meant to eat carbohydrates.

2:45  Two things that prove that humans were not meant to eat carbohydrates.  First is insulin.  Do you know that we have the wrong type of insulin for carbohydrates?  Think about it.  When we eat carbohydrates, our blood sugar spikes, insulin goes up but then blood sugar drops down too low because insulin keeps going, so we have to keep eating more carbs and more insulin.  We keep having this balance throughout the day, and we can't get our blood sugar right as a result.  Did you know that we had to reinvent insulin for Type 1 Diabetics and Type 2 Diabetics who require insulin? So instead of just giving   

DR. ANTHONY CHAFFEE: If I Started Carnivore in 2026, This is What I’d Do [FULL BLUEPRINT]

Dr. Anthony Chaffee. 

3:28  People who at more saturated fat had fewer strokes.  Those who ate less saturated had more strokes.  Hmm.  I think I'll choose more saturated fats. 

3:44  If you're cutting out fat as well, then the majority of your calories are going to come from protein.  Even if you have excess body fat, you will still break down large amounts of that protein to either use as energy or store.  As such, when you break down amino acids, you necessarily release a nitrogen group that then gets turned into ammonia and that's further transformed into urea in your liver.  However, if you are eating too much protein, then this will build up the amount of ammonia that your liver has to process and it gets overwhelmed and you get a build of an excess of ammonia and this can actually cause very serious harm.  This can cause liver damage, and your liver enzymes might go up where on a normal high-fat carnivore diet you will never see that.  The ammonia can also cause organ damage to the rest of the body, cause neurological issues.  You'll have extremely low energy.  You can start losing your hair, and this is a symptom people have been seeing recently because they've bought into the whole nonsensical low-fat carnivore idea, and then they're told that this is probably being in ketosis and ketosis is harmful.  But if it were harmful, then none of our ancestors would have been able to exist through the Ice Ages when there were no carbohydrates available.  All the Inuits would be dead.  And I would be dead because I've been doing this for over 8 years now, and 5 years in my early 20 have had no carbs in that entire time apart from what comes naturally in meat.  However, when people are new to this and don't understand that ketosis is our natural metabolic state and not a harmful state, 

DR. ANTHONY CHAFFEE: Humans are apex predators, top of the food chain. What other apex predator eats salad?

He hasn't eaten a vegetable in over 5 years...

Humans are apex predators, top of the food chain.  What other apex predator eats salad?  There are things in meat that you have to have that you cannot get from plants, but there is nothing in plants, or fungus, that you have to have that you cannot get from meat.  So you have to eat meat, and you certainly don't have to eat plants and I would argue that you don't want to eat plants for optimal health.
