Dr. Cate tells us how learning the truth about seed oils and cholesterol changed everything.

While living in Hawaii, the healthiest state in the US, I realized most of the locals had benefitted from eating traditional diets that were shockingly different than what I was taught a healthy diet looked like. It was high in cholesterol, which made me question the validity of my nutrition education. Was cholesterol really the cause of heart disease? I was shocked to discover the truth about the nutrition science all doctors and dietitians learn. Applying my biochemistry training to the problem of heart attacks, I discovered vegetable oil causes heart attacks, not cholesterol. And the cure for heart disease–and everything else–are the traditional foods that feed our DNA the Deep Nutrition it craves.

What is Deep Nutrition?

Physician and biochemist Cate Shanahan, M.D. examined diets around the world known to produce the healthiest people—diets like the Mediterranean, Okinawa, and “Blue Zone”—and identified the four common nutritional habits, developed over millennia, that unfailingly produce strong, healthy, intelligent children, and active, vital elders, generation after generation. These Four Pillars–fresh food, fermented and sprouted foods, meat cooked on the bone, and organ meats—form the basis of what Dr. Cate calls “The Human Diet.”

Rooted in her experience as an elite athlete who used traditional foods to cure her own debilitating injuries, and combining her research with the latest discoveries in the field of epigenetics, Dr. Cate shows how all calories are not created equal; food is information that directs our cellular growth. Our family history does not determine our destiny: what you eat and how you live can alter your DNA in ways that affect your health and the health of your future children.

Saved my life

I would like to thank you for literally saving my life. Back in February, I had to be hospitalized while on vacation in Phoenix with an A1C of 11% and had to start taking 2 types of insulin and 2 other meds. I read the Fatburn Fix in April, and followed the program to a tee, and I’m down by 15 pounds, 6.8 A1C, and only one once weekly diabetes medicine. Prior to reading the book, it was almost impossible for me to lose weight as a diabetic.

I feel free

For the last month, I have really been reading all labels on everything. I have completely remove those 8 oils you talk about. I must tell you, I feel great! I have more energy and I am now 197 lbs (have always been around 205 to 210lbs). I eat potatoes with real butter, grass fed steak, pasta with the right toppings. I eat everything! I seem to crave less sugar. I love it!

I feel so much better

I had terrible aches and pains everywhere in my body, my hands, shoulders and knees. I feel so much better and the way I feel is motivating me every day! Thank you

Better than ever

I am an anesthesiologist in Orlando and a huge fan of both of your books! I have been incorporating your principles for the last 10 months and feel that my health is better than ever.

My allergies disappeared

The biggest difference for me (and a surprising one) is that my allergies have almost completely disappeared! This is a big deal for me, because I’ve had allergies most of my life and they have often affected what I do which is a teaching music in [a public school district].  In general, I feel much better and have more consistent energy throughout the day.

Heart Palpitations have Stopped

I’ve lost 20+ pounds (also fasting 16-24 hours daily) and haven’t had palpitations except for one occasion — I had a mini bag of Fritos for the first time in July. And, I feel better now on a daily basis than I ever did all through college.

I’ve lost over 50 pounds

I’ve lost over 50 pounds. I’m 56 years old. Cutting processed food and unhealthy fats from my diet was one of the first things I did on my health recovery journey...I went cold turkey off the bad oils. Emptied my pantry into the trash and just started eating real food

Knowledge I didn’t know I needed

Your Fatburn Fix book is amazing, my friend. Thank you! I’m an Functional Nutritional Therapy Practitioner and I know my stuff. This is the extra layer of knowledge I didn’t know I needed. Well done!

Lost a solid 20 lbs and my bloodwork is great

I have lost a solid 20 lbs and my bloodwork (after 3 months of eating your way) was even better! I was metabolically healthy (per your book) before I read your book, but barely. Lowering my weight, sealed the deal! I have been talking about you and your book to anyone who will listen...Thank you for all you’ve done and what you continue to do! You are changing lives for the better!

Lost 20 lbs I could never shed

I love your Fatburn Fix!  Has helped me so so much!  I have had the dreaded weight all my life - 20 or so pounds I could never shed.  I have lost that now. I only eat 2 meals a day lunch and dinner with a glass of milk or cappuccino around 4 to hold me over. No snacking and not bad oils.  It has been the key to unlocking my fatburn.  I work out in the am and believe I am burning fat for energy not from food!

I feel great

My waist is four inches smaller. I feel great and many of the minor aches and pains that I had (knees and lower back) are gone. Also, my muscle tone is amazing, even though I have not increased my workout routine.

No one is better at communicating nutritional truth

Dr. Cate has had the single greatest impact on how we talk to people about fueling for both performance or durability. While we all are a little unique, the foundational principles of human nutrition are immutable. If you are looking to create a more durable, resilient body, no one is better at communicating nutritional truth than Dr. Cate.

Highly recommend The Fatburn Fix

Dr. Shanahan has had a significant impact on my practice of medicine. I am known as a Low Carb Doctor, but I never really appreciated the negative effects of processed seed oils on the health of my patients. I highly recommend The Fatburn Fix to my patients and have a loaner copy in my waiting room. It is amazing how quickly blood sugars and overall health improves with cutting seed oils. It is not just about the carbs!

Dr. Cate reordered my diet when I was with the L.A. Lakers, and the benefits, for me personally, were felt immediately and have served me to this day. I’ve come to take real food so seriously I started a small family farm. I know of no M.D./nutritionist more respected in the sports world than Dr. Cate Shanahan.

Pull up a chair…

I have based my work on the idea that getting the right kinds of healthy fats into your body and avoiding the worst fats is essential to optimal health. I've interviewed dozens of the world's top experts about this, and I know of no one who speaks more eloquently on this topic than Dr Cate. If she’s talking fats, pull up a chair. Take notes.

Why Read Deep Nutrition?

Deep Nutrition is unique because it is the only book that gets you back to the diet we abandoned very recently. Within the past 50 years or so, we were convinced to abandon the diet that had been working for us for thousands of generations. Deep Nutrition is the opposite of a fad diet; it’s simply returning us to what kept us healthy before the epidemics of overweight and diabetes began.

Anyone who says that we still need more research to get to the root cause of any one of these diseases that is increasing, like overweight, diabetes or even cancer and Alzheimers, is simply not well informed. Everyone who seriously studies nutrition and its connection to health comes to the same conclusion: The modern diet is killing us and we’d do better to get back to the diet we all used to follow before so many of us started getting sick.

The most important concept in the book is this: The idea that Sat Fat is bad was based on fraudulent science–and I give you the evidence that convinced me this was the case. What it did, was open the door to selling more processed food. That’s why we’re sick. So you don’t have to go back 20,000 years and eat like a caveman, nor do you have to give up all animal products for fear of their saturated fat content. All you need to do is go back to the same diet everyone used to follow before we all started getting sick, what we call the Four Pillars of The Human Diet.

What is The Human Diet

The Human Diet has the longest track record of success. You may have to dial your family history back a century or two, depending on where you were born. Sooner or later you’ll bump into folks who grew what they ate and ate what they grew. This is how people survived for thousands of generations and I saw its beneficiaries in action during my 11 years in Hawaii—the state with the best longevity statistics in the US. My patients in Hawaii originally hailed from all over the world, and when they got to Hawaii, they brought their knowledge of growing and cooking with them. This sort of know-how composes a body of wisdom I call Deep Nutrition, and I wish I’d learned how it works during my training. If everyone alive today had grown up eating this way, we would be living in a healthier, beautiful world.

With 2x content and 3x the references, the new Deep Nutrition has a lot to offer.

What’s New in the New Edition?

  • When I wrote the 2009 edition I was living on Hawaii. Hawaii is the healthiest state in the US, and, I didn’t realize until I moved back to the mainland, that the generational decline in health I had noticed in Hawaii was even more dramatic back on the mainland, particularly health problems that result from impaired immune system function. So this edition addresses food intolerances, notably dairy and gluten, along with other issues I encountered far more often after relocating.
  • Speaking of gluten, when I wrote the 2009 edition, almost nobody had heard of it. Today, one in five Americans say they are gluten-free. Considering that gluten constitutes about 1 %  of the average person’s diet, and vegetable oils constitute 25-35%, I’d say that it’s past overdue that we pay more attention to these industrially processed fats and their potential connection to disease. With that in mind, I’ve expanded the original Good Fats and Bad chapter to help expose the link between vegetable oils and cardiovascular disease, and included an enormous, entirely new chapter, Brain Killer, describing how vegetable oils promote oxidative stress that leads to impaired cognitive function at every age. The idea is to make it clear that if you had only one dietary change you could afford to make, this should be it.
  • When I wrote the 2009 edition, the current low carb craze was just barely beginning. Now, many millions of people are abandoning the high-carb breakfasts, snacks and other junk and going back to eggs, cheese and other real, natural fats. This has created a very special problem, because in some cases, in spite of weight loss and reduction of medication dependence (for diabetics in particular), people’s total cholesterol will go up and their doctors advise them to start statins, often wrongly. So this edition includes information for both readers and their doctors on why this happens, how to tell if something is wrong, and why not to just assume a statin will help.
  • When I wrote the 2009 edition, the rise in autism and other childhood developmental disorders was just barely being noticed. Now, it’s very clear that autism is increasing and, the question now is what’s behind the epidemic. This edition reveals the science that connects the consumption of vegetable oils and excessive carbohydrates to the epidemics of autism and other childhood problems, in order to better empower parents with tools to protect their family’s health.
  • One of the most novel and controversial ideas in the original Deep Nutrition is the idea that birth order affects our looks by impacting skeletal development, and that subsequent siblings may be at a disadvantage, health wise. This edition expands that concept, originally called second sibling syndrome, to highlight how, in the context of a modern diet, there are also disadvantages to being born first. The goals of including this new information are twofold. First, to help prospective parents understand the absolute power they have to control the outcome of their children’s futures. And second, to help you recognize two patterns of skeletal asymmetry that predispose us to develop certain injuries so that you can recognize them before you hurt yourself.

How Following Principles of Deep Nutrition Changed One Woman’s Family

“If you are looking for a book that makes nutrition compelling, terrifying, and practical all at once, this is it.”

Caroline Vallandingham reached out to me to ask if I wouldn’t mind linking to her review. Of course, I read it, and I have to say she really gets the book. She had already adopted many Deep Nutrition principles by reading numerous other books but nevertheless got a lot of new information and useful insights. Her story is also worth a read.
