The Hateful 8 are the Bad Seed Oils We Need to Avoid
Every day you probably hear health and diet information delivered as gospel by doctors and scientists from the most respected institutions in the country. The rules of the media game typically require that the experts brought into the spotlight will be parroting the same information you’ve already heard thousand of times before. This is especially true when it comes to fats.
But Bill Maher isn’t afraid of rocking the boat. On Friday May 22, 2020, when one of the few in big media willing to talk about the relationship between diet and health like a grown-up, Bill Maher, invited me onto Real-Time to share some truth. (Short segment here, full audio here on stitcher, intro to my segment starts at 17:15)
"Let me tell you this has been life-changing. I have all of her books, in audible and ebooks! I have gotten rid of all the hateful 8 oils. I have trained my body to eat its own previously toxic body fat. Download that pod it's a game changer!"
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!

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

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!
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.

Here are some of the things we discussed.
Most Folks Don’t Know They’re Eating Seed Oils
The average American gets 80% of their fat calories from seed oils, which are high in unstable fatty acids that break down into toxins when you cook with them and when you eat them for years and years. This problem is pushed under the rug and nobody is talking about it. The American Heart Association wants to keep it that way.
Seed Oil Weaken Your Immune System
Eliminating the high-PUFA seed oils is the NUMBER ONE best thing you can do to help your immune system beat Coronavirus. Here’s why.
The virus is not what’s killing most of us under the age of 65. For the elderly, or for those who are otherwise immunocompromised, the sheer viral load can be too much for the body to deal with. But for the rest of us, the real threat is not the virus itself, but the way your body responds.
Most of the folks under 65 who have to be admitted to the ICU are there because their body fat is full of inflammation-promoting high-PUFA seed oils. In other words, if seed oils were removed from the equation, then there would be nobody under 65 in the ICU unless they’ve got a rare immune deficiency disorder or are in the middle of chemo for cancer or have something else very serious that’s going on.
What I’m talking about goes way beyond flattening the curve; the sheer volume of the curve would be reduced. If the Hateful 8 weren’t disrupting our metabolisms and forcing our immune system to produce dangerous levels of inflammation, kids are still at school, restaurants are still opened and people are still going to work.
During the interview with Bill Maher, I also made the point that everyone under 65 who had a serious case of corona also has an underlying metabolic condition–whether they know it or not. Even those thin people who’ve written articles about their experience, like Mara Gay, a reporter for the NY Times who looks glowingly healthy.
As fit and beautiful as she appears in the NY Times piece, it’s unlikelyher metabolism is in good shape. Your metabolism has to be very damaged indeed for it to cause visible signs of poor health. But it doesn’t have to be particularly damaged for it to fail you when the time comes for your immune system to rise to the challenges involved in what may be the ultimate metabolic test: fending off potentially deadly infections.
I’m so sure that seed oils are the underlying cause of metabolic disruption that I’m calling for a challenge. Show me a single person under 65 without a serious underlying disease or immune deficiency who ended up in the ICU who had been categorically avoiding vegetable oils for the prior 5 years and you’ve proven me wrong.
Keep in mind, I’m not just talking about avoiding trans fats from hydrogenated oils, which a lot of people think are the only bad fats to pay attention to. I’m talking any of the Hateful 8, hydrogenated or not.
Your Immune System Needs You to Be Metabolically Fit
Doctors are so poorly trained in metabolic disease that most can’t begin to appreciate how powerful the wrong dietary advice they typically dish out is disrupting your health. We tell you to avoid saturated fat and when you do you’re going to end up eating unhealthy amounts of PUFA. And so most doctors unknowingly give out nutritional advice that only makes people sicker. When our dietary advice fails to help our patients, we sometimes avoid the subject altogether by ignoring abnormal lab results and telling you “all your tests came back normal.”
That’s my best explanation for why half the adults in this country with metabolic conditions like fatty liver and prediabetes aren’t told they have the condition, and therefore don’t have any reason to believe they’re at risk for additional complications of metabolic diseases or at risk of suffering from serious infections.
Many other common conditions are also metabolic. For example, if you’re a person who suffers from frequent migraines, seasonal allergies, occasional asthma, you almost certainly have an unhealthy metabolism. These seemingly minor underlying conditions are enough to make a viral pneumonia potentially life threatening.
It’s not that migraines or allergies disrupt your metabolism. It’s that the underlying condition that causes migraines, allergies, and many other seemingly unrelated metabolic illnesses, is too much PUFA in your body fat.
Most people in the ICU are not eating, and that’s when these seed oils are going to be released from your body fat–during fasting. When released into the bloodstream, these PUFAs interact with enzymes that are part of your virus-fighting, immune-response team. Their function is to promote inflammation, in fact, that’s one of the key reasons a healthy diet includes about 2-4% PUFA. But the problem is, on a modern diet with 10-20X the normal amount of PUFA, our body fat releases 10-20X more PUFA into the bloodstream, and we get 10-20X more inflammation than we normally would.
That insanely high level of inflammatory chemicals in our bloodstream, lungs and other tissues causes metabolic pandemonium. We start drowning in our own fluids and can’t oxygenate our blood. Inside our arteries and veins, the platelets that are supposed to form clots only in response to cuts instead start clotting randomly inside uninjured vessels, causing neurological problems, heart attacks and strokes. Our immune system starts mounting attacks on innocent bystander proteins, like those in our blood vessel walls, causing rashes that are the hallmark of the new Kawasaki-like, life-threatening COVID-19 complication in children and young adults.
Four Steps to Start Eliminating Seed Oils From Your Body Fat TODAY
Make your own salad dressing. Even if you buy your organic, GMO-free dressing at Trader Joes or Whole Foods, chances are it’s made from one of the hateful eight oils. This applies even if the front of the bottle says made with olive oil. You always need to read the ingredients. So take a snapshot of this hateful 8 and keep it on your phone. Or better yet, use this one that gives a little more detail.
Take a good look at the ingredients in what you eat. Scan anything with an ingredients list for one of the members of the Hateful 8 clan. If you want alternatives, here’s a shopping guide to finding vegetable oil free products available in some of the most common grocery stores in the USA.
Support restaurants that refuse to use the Hateful 8. There are numerous excuses you will hear why a restaurant doesn’t use olive oil or another healthy, traditional fat. Canola is heart-healthy. We use soy instead of peanut because of peanut allergies. It’s a neutral taste that people prefer. It’s got a high smoke point. Those excuses are the best marker I know of for a chef who has lost his passion. Whenever we’ve found a chef that proudly tells you he only uses olive oil and butter, or any of the good fats, we’ve also found the food coming out of the kitchen to be absolutely the best.
Find out how much vegetable oil is in your body fat. While there’s no direct test other than doing a subcutaneous fat biopsy and sending it to a lab for a full analysis, which you can’t do unless you’re part of a research study, you can get a decent idea of how your body fat is impacting your metabolism by finding out if you are insulin resistant. Ask your doctor for a HOMA-IR test. If he doesn’t know what it is, in most states in the USA, you can order a test yourself. Visit this website for more information and select the “Insulin sensitivity Test, HOMA-IR.” It only costs about $45. Or ask your doctor to order two tests at the same time: fasting glucose and fasting insulin level. Then plug your numbers into this calculator. And given the reality of no direct testing, I created a clinical questionnaire to aid in assessing your recovery from PUFA overload. It’s published in The FATBURN Fix, and you can download it for free by entering your email in the green form at the bottom of this page.

Is a natural ingredient made from the seeds of castor oil. Is this safe? I do not understand how to categorize when I see seed oil/ something made from seeds like the above ingredient, on a non-cooking oil label, and using it as something topical is it safe?
Hello, Dr. Cate. I am wondering if things like carrot seed, oil and coriander, oil, and other essential oils that are made from the seeds are safe to use topically or internally either or. We use a lot of essential oils in our home and I’m beginning to make my own lotions and selves, and I need to know if I can include these ingredients safely a skin care product specifically but we also use them with cooking at times.
Thank you for your reply Dr. Cate. Why is it that the other ones that are not part of the hateful eight are molecularly stable and/or are ok to use/ingest?
If this is already covered somewhere in your website, I apologize. I looked, but I did not find anything.
Dr. Cate,
I heard you on Dave Asprey’s podcast and was inspired to learn more. When I search “hateful 8 seed oils” I come across several articles (such as this one: https://www.consumerreports.org/health/healthy-eating/do-seed-oils-make-you-sick-a1363483895/ ) that reference research, including a meta-analysis I’m sure you’ve seen: “in a review of 30 studies published in 2019 in the journal Circulation, scientists found that linoleic and arachidonic acids levels didn’t raise the risk for heart disease. In fact, those with higher amounts of linoleic acid in their bloodstream were 7 percent less likely to develop it.
“Another study published in 2018 in the American Journal of Clinical Nutrition that followed nearly 2,500 men for an average of 22 years found that those with the highest blood levels of linoleic acid had a 43 percent lower risk of dying from any disease during the study period than those with the lowest. Higher blood levels of arachidonic acid reduced the risk of dying by 20 percent.”
I would love to hear your responses to these articles. It might even be worth your time to post comments on some of the top results for such a search.
Had switched to peanut oil some time ago and was amazed at just how much more digestible it seemed. Have put oil on pasta forever only to discover the peanut oil was not “heavy”! In the stomach as corn or soy seemed to be. Likely consumed two or three gallons the first year and that has dropped by half in the second year as you feel better and want less somehow. Household consumption not personal. Btw.
I am a very young 63 year old. I am vegetarian and participate in just about any and all healthy nutrition regimes. Here is my pet peeve, why is it almost impossible to find any (and I mean any) product in a Whole Foods, Sprouts, Natural Grocers or any other advertised food source market without every single ingredient list containing, Soy, Canola Oil and various seed Oils such as Sunflower seed. It is so frustrating!! 🙁 🙁 🙁
Hi Cate! Have you done any research into how these oils effect animal health? When all these warnings came out about grain-free dog food potentially causing heart health issues, veterinarian cardiologists suspected that it was due to the legumes that often replaced the grains in these suspected grain-free formulas. When you look at the ingredients of most manufactured dog food and dog treats, you’ll find that they include at least one of these seed oils though. Could this be the culprit behind the rise in dogs suffering from heart health problems?
Hi Dr. Cate, How do I rid my body of excessive bad oils that I have? I have been following your eating recommendations in Deep Nutrition. Would fasting help eliminate them?
Hi. Thanks for all the info. Confused about a few things. I’ve been making bread from baking golden linseed flour (done with vitamix) at 180 centigrade in oven with salt and water as an alternative to grain bread. Is this problematic? Also, what about making one’s own nut milk by blending nuts in vitamix then heating it in pan? And I would be extremely grateful for thoughts on nut butters and if the way they are made leads to dangerous oxididation. Many many thanks.
Would you say that skincare products that contain sunflower seed oil are still to pose a threat to the immune system? I know that our skin absorbs what we put on it, so I would assume so. However, I’ve also read that only oils that are heated at such a high temperature are when it really gets bad and releases all the toxins into your body.
It’s not a lot of a dose, so if you can’t get it without those oils it’s not a deal-breaker. However, my supplements page lists D that has good oils. https://drcate.com/recommen…

Yes its on my to do list!
Oh no! I just discovered that my ‘go to’ whey protein powder has sunflower lecithen. Does anyone know of a whey protein powder without PUFA’s?
