Plant-Based vs. Animal-Based Diets

Plant-Based vs. Animal-Based Diets

I received a good question from a reader after she saw one of my articles where I discussed my 10 years of nutrition research and findings.

This is what Kelly said:

I have a question after reading Ariel’s latest article about doing your own research. I find raw food exciting and am currently in transition. The one thing I am struggling with is all the testimonials of people who have overcome their issues with, say, Keto or Carnivore and never felt better—when nothing else worked, from cancer to depression. Now, the big thing is the “Metabolic approach.” I am just struggling to understand all the big-name doctors actually follow the plan themselves. Do you think maybe one diet does not work for all? I am just curious about your thoughts, as it is so confusing.

Thank you for all the work you do!


Dear Kelly. I understand your concern. If you search the internet, you will find very convincing cases made by authors and doctors about why we should eat keto and meat-based diets instead of plant-based ones—I also constantly come across those. Sadly, the internet is plagued with them.

In all honesty, providing a compelling response to your question in just a few paragraphs seems quite impossible, considering that researching nutrition and natural health typically takes an average of seven years, as mentioned in my article. After all, if it only took a short time, why would I invest seven years in studying, right? Nevertheless, I’ll attempt to address your query without making this post overly lengthy.

Have you ever wondered why a doctor’s work isn’t focused on preventing disease rather than pretending to ‘cure’ disease with drugs – which works by suppressing symptoms, which is what most pharmaceutical drugs do? QUICK ANSWER: Because that is what makes money. Preventing disease is not really a business because you can’t sell drugs to healthy people. You may think that’s not right, but that’s how things work in our world.

The same goes for politicians and their actions. Many of them promote policies to enrich themselves and their friends or class without caring if most people in their country suffer. I see a lot of them. Whether it’s ignorance or immorality, I don’t know. Many of these politicians are simply corrupt, and, again, it’s just the way our society works.

The reason you have many authors and doctors selling books and programs on Keto and animal-based food diets is that they saw a market for it—of “billions” of people hooked on eating high-fat diets and meat—and want to make money. They don’t care about your health or anybody else’s. Whether it’s ignorance or fraud, I don’t know. The truth is that they pervert science to make money. If you study nutrition and other health sciences long enough, you’ll find that it’s (actually) very easy to confuse people with scientific studies, etc. “Metabolic approach” is another BS marketing term they use to fool people and it means absolutely nothing.

If you care about your health and well-being, you need to get these people who promote the consumption of animal products off your radar. Just ignore them – all of them.

And to answer your other very good question: The reason you hear or read testimonials of people overcoming disease by eating a meat-only diet is because of EVERYTHING ELSE THEY DON’T EAT. If you cut out all processed and refined foods from your diet – no grains, no ice cream, no pizza, no potato chips, no candy, no soda, no cookies, no sugary snacks, etc. – and all you eat is steak, as celebrity psychologist Jordan Peterson apparently claims to be doing, then you might be able to get rid of a lot of diseases because of all the junk food YOU’RE NOT EATING! But not because of the steak you do eat. Do you understand me?

However, this approach is a time bomb because you are guaranteeing that your health will plummet in due course, as animal-based foods are highly deficient in many important nutrients your body needs. They are low in fiber, Vitamin C, minerals such as potassium and magnesium, and the thousands of phytonutrients that can only be garnered from plants.

If you come across “scientific” studies that contradict what I say, it is because they are paid for by the meat industry. These studies are all rubbish and you should ignore them completely!

Dear Kelly, have you ever watched the Discovery Channel and seen the instinct that lions have to kill and eat their prey? Do you have the same killing instinct to kill and eat a cow or to eat raw what is left of a bloody animal on the ground? The answer is NO. And that is because humans are neither carnivores nor omnivores.

Humans are meant to be frugivores, eating fruits, vegetables, some green leaves, and other plant products. Everything about our bodies, from our physiology, anatomy, biology, and psychology indicates this to be true!

As for the other question you asked me about, whether one diet fits all, the answer is YES, ABSOLUTELY!

It’s important to note that Nature has provided the perfect diet for every creature on earth, and animals of similar species have similar dietary preferences. Consider, for example, elephants and other large herbivores such as rhinos and giraffes – all fall into the same category of creatures designed to thrive on specific plant-based foods that suit their biological systems.

It’s crucial to reject any notion that suggests humans are exempt from the Law of Similars, a principle observed throughout the animal kingdom. There are no exceptions; animals with comparable anatomy and physiology thrive on comparable diets. Cats are carnivores; you’re not going to find some cats eating apples and oranges, are you?

To sum it up: If you have never read the book “Fit For Life” by Harvey and Marilyn Diamond, first published in the 1980s, I think you should. At one point in the book, when discussing our natural diet, Harvey Diamond writes: “Kids are the real test. Place a small child in a crib with a rabbit and an apple. If the child eats the rabbit and plays with the apple, I’ll buy you a new car.”

What do you think, dear Kelly? What does your common sense tell you? We are apple eaters by nature, not rabbit eaters, are we not? Anyone who manipulates science to make you believe that humans should eat rabbits instead of apples is ultimately either ignorant or a con, and you should ignore them. It’s as simple as that!

    I’m 63 years old and haven’t eaten meat since 1981 (the year I cured myself of Stage 3 cervical cancer by switching to an all raw diet of fruits and veggies, distilled water fasting, and colonics for 6 months). Many people say I look to be in my late 40’s.

    I really enjoy your e-,mails and want to thank you for the great advice you give to many people, like Kelly. Even after researching the positive effects of raw food’s for over 40 years, I still learn useful information from you! I was wondering if you have ever read Dr. Norman Walker’s book, Becoming Younger? It’s what saved me and is a great learning tool for those on the raw food path.

    Thanks again for all your information!

  2. Hi, Ariel, “You are what you do NOT eat.” This is why, for example, celery juice fasts or water fasts work, and the same principle as you mention keto or paleo diets. . If after going off these fasts or whatever they’re giving up, they go back to eating their old diet, they get sick again.

    I do enjoy reading your newsletters. Keep it up!

    Your article make total sense. I will read that book and am excited for this new venture! I love to read testimonies of people who have over come health challenges through rawfoods!Thank you Victoria! So glad to have all your expertise as I embark on this journey. Keep the newsletter coming!


  4. Very well said Ariel 🙂
