H. L. Newbold


Dr. Herbert Leon Newbold as pictured on the dust jacket of one of his books.

Dr. H. L. Newbold was the first place I encounter the idea of an all-meat diet. He published a number of books throughout his career, but his last one The Type A / Type B Weight Loss Book published in 1991 is by far his best overall book on diet. It represents the culmination of everything he had learned about health and nutrition up to that point in time. He practiced orthomolecular medicine and was a colleague of Linus Pauling, as well as Dr. Robert Atkins. He also worked with and was greatly influenced by Dr. Theron Randolph whose work is described in his excellent book An Alternative Approach to Allergies.

Dr. Newbold’s private practice was located in New York City. His untimely death in 1993 at the age of 72 was apparently caused by an anaphylactic reaction to an antibiotic he received in the hospital while being treated for some type of infection. I have no idea what happened to his patient’s medical records, but I would love to get my hands on them. He presents some fascinating case histories in the above mentioned book, and I imagine he had many more like them that could not be included in that small volume.

Dr. Newbold worked extensively with people who suffered with obesity and eating disorders. He found that many of his patients were able to lose weight and stop destructive eating behavior if they ate an all-meat diet comprised almost entirely of beef. He allowed other meats as well, but – over the years – he discovered that the majority of his patients thrived on fatty ribeye steaks. Unlike Atkins, he does not single out the macronutrient carbohydrate as being the main culprit in his patients’ eating and weight problem.

Rather, Dr. Newbold takes a step back and points to what he called “new foods” in the human diet, i.e. foods such as grains and sugar as well as dairy and eggs. He felt that some people were genetically less well-equipped to handle these kinds of foods. Yes, many of these foods were high in carbohydrates, but he felt that the bigger issue was that people could become allergic to them. He explains that when a person is allergic to a food, it not only becomes addictive, but it also causes weight gain by interfering with proper hunger signaling and causing the allergic person to develop disordered eating.

People with “Type A” obesity – when triggered by an allergic food or chemical – would spree eat or binge on anything sweet they could find, while people with “Type B” obesity – when triggered by an allergic food or chemical – would have to eat a certain sweet food at regular intervals in order to feel satisfied and to avoid “withdrawal” symptoms. He noticed that the trigger foods were always from the category of what he labeled as food new to the human diet.

In other words, people don’t eat a steak and then feel like bingeing on cake and ice cream. Most people in his experience were not allergic to beef, or meats in general, and could eat them without having their appetite signalling go haywire. But for someone who is allergic to wheat eating one cookie can send them on an eating spree that would put the Cookie Monster to shame (Type A). Or, someone may find that they must have their cookie fix at least once every day in order to feel okay (Type B).

In addition to “new foods,” Dr. Newbold also found many people had allergic hunger that was triggered by environmental factors such as pet dander, pesticide sprays, copy paper ink, perfumes, gas pilots lights, florescent lighting, tobacco smoke, lipstick, and many other similar things. So, if you are trying to follow an all meat, or Zero Carb, diet and find yourself continually getting derailed by cravings, you may find Dr. Newbold’s book to be extremely helpful. Since an Zero Carb diet eliminates all foods derived from plants, it can go a long way in helping a person to overcome cravings for sugar-rich foods.

But Dr. Newbold also found that even some of the ‘”newer” animal foods we eat – namely, eggs and dairy – can also be incredibly problematic for some people. He has a case history of one young woman who was addicted to milk. She drank gallons of it every day. However, the damage caused by her addiction to milk went far beyond her weight. Not only was she quite obese, but she was also mentally impaired. She was still living at home with her parents and was unable to function normally in the world. Once Dr. Newbold got her off the milk, she went on to live a very happy and satisfying life.

It is my opinion that Dr. Newbold was one of the great medical minds of the last century. It is unfortunate that his accumulated knowledge was never given a very broad audience. All of his books are now out of print and must be obtained from used book sellers. It is my hope that his work will one day be brought out of obscurity and examined more closely in the light of modern research. In the same way that Dr. Jeff Volek resurrected Dr. Stephen Phinney’s Low Carbohydrate research and brought him out of retirement, Dr. Newbold needs an advocate who recognizes what a brilliant mind he was. The Type A / Type B Weight Loss Book should definitely be included on the list of essential reading by anyone who wishes to eat an all meat diet.

  2. like like like!!!!!! You pointed out this book to me in December and it has been such an eye opener to me… found one answer after the other – and I can assure you I had been reading dozens of books on this subject!


  3. What concerns me a little bit is that H.L. Newbold died from lymphoma. Stanley Owsley also died from cancer. And both men had heart disease.

    What do you think about it?

    Wikipedia says:
    “Risk factors for common types of non-Hodgkin lymphomas include autoimmune diseases, HIV/AIDS, infection with human T-lymphotropic virus, EATING A LARGE AMOUNT OF MEAT AND FAT, immunosuppressant medications, and some pesticides.”


    • I spoke with the pharmacist Dr. Newbold used in his medical practice shortly after he died. He told me what I wrote in the post, anaphylactic reaction to antibiotic. I have never been able to verify what happened beyond this. It is impossible to say what exactly happened. However, yes, he did have a heart attack (which he discusses in his book) and that is what prompted him to change his diet and gave him another 20-30 good years. Like anything else, though, it is impossible to know all the facts unless you knew him personally. How much stress did he experience, etc.? It is also important to keep in mind that that he was extremely sensitive to just about everything, both foods and chemicals, so it is not like he was a perfectly healthy person who took up an all meat diet. He went to an all meat diet because that is what worked best for his body. He also found that an all meat diet worked best for many of his sick and overweight patients. To really understand him, it is necessary to read his book.

      Stanley Owsley did not die from cancer. He died from a car accident. His cancer was caused by a chronic infection in his tonsil due to scar tissue build up and improper drainage. It is also important to remember that Owsley used a lot of LSD during his life and lived a stressful life on the road managing the sound system for the Grateful Dead concerts. Again, it is impossible to know all the facts.

      I consider both of these men to be pioneers, but neither of them were perfect nor infallible. Take what works for you, and leave the rest.


  4. I’d rather die at 70-80 of cancer or whatever, then live the next 30-40 years of my life on powerful anti-depressant and bipolar meds, which all meat has enabled me to drop!!! Not that I have to choose, or want cancer. But I recognize that I have to die of something and I’d rather be vibrantly healthy, happy, and energetic up to that point than live with low level chronic illness and degeneration, and mental instability that requires major pharmaceutical intervention for the rest my life… That being said I don’t know if I’ve seen many people try all meat “just because”… They’re usually dealing with medical issues or want to seriously improve their health.

  5. (Almost) every writer somehow connected to an all-meat diet seems to link its benefits to overweight people – what about skinny people ? The reason I ask is because this diet does seem to work perfectly for the overweight but does it benefit people who aren’t ? I am thin and always was – the reason I want to try this diet is because of certain health problems I have but obesity/insulin resistance isn’t one of them.
    I remember Dr. Atkins wrote this diet will benefit most people but not everyone – do you know what he meant ?
    Sorry for this stupid question, it’s just an under-adressed issue ( all meat diet for people without weight issues )🙂

    I also want to thank you for this wonderful website – the information is priceless – thank you for putting all of this online.

  6. Just burning the pilot light on our gas heater (even though the heater is vented to the outside) will start me flying stupid after about three days no matter what my diet is. Jet fuel during travel has much the same effect. From where I sit, there is much to be learned about the immune system.

  8. I was very fortunate to be a patient of Dr. Newbold for several years. He saved me from becoming mentally disabled due to my many food allergies. Dr. Newbold was a great believer in eating foods that related to your ancestry. I am of German descent and he named the foods I should eat and the ones to be avoided. Therefore, the steak diet he recommended worked well for me. When I first went to him, I was hooked on a Spanish brand of champagne. I became so anxious and panicky that I was afraid to go outside. He said he wasn’t surprised since formaldehyde was the root cause of this reaction which was added to that brand of champagne to increase shelf life. I definitely stopped that. However, I did cheat on other occasions and started eating croissants with brie cheese and forest ham and after a week or so, I could actually see my skin crawl with some kind of maggots (wheat caused hallucinations). I had gone to a dermatologist and told him that I thought I had lice (felt like bugs crawling on my scalp). After two visits with no results, he sent me to a psychiatrist. He said I was exhibiting schizophrenic behavior and needed to be evaluated.. I went back to see Dr. Newbold and he told me to stop eating bread and the symptoms should be eliminated in 3 days. Sure enough it stopped. Lastly, I was losing my balance and I had to hold on to the walls when walking so I wouldn’t fall over. I visited Dr. Newbold again and he said it was the hormones in the eggs that were the cause. Just like before, I stopped eating the eggs and the symptoms went away. I am forever grateful to Dr. Newbold for saving me from a life of pain and suffering. He was a brilliant scientist and the knowledge he had was to vast to be covered in the few books he had written. You would have to experience it to see what a wonder he really was. (Linda Longstreet)
