NIX CARBS

LEGAL DISCLAIMER: I am not a doctor, nor do I play one on TV. Everything on this site is my opinion or the opinion of those referenced. Nothing here is meant to be medical advice. While I advocate for certain lifestyle choices, do your own research and talk to your doctor before making changes.

A mere 300 hundred years ago, our ancestors primarily ate food available near their home. Some simple items that keep and travel well, like salt. pepper, and tea, could be purchased in bulk from places far away.

They feasted on foods seasonally and rationed through the year. This means fruit was plenty during harvest time, like the fall. One could eat plenty of a couple types of fruit roughly once a year. Canning to preserve food was not invented yet. Our ancestors could dry the fruit or make a crude wine, but keeping it safe from critters was difficult. During the other ten months of the year, the primary food source for most of the world was meat raised or hunted locally.

Additionally, the food was very different from what we recognize today. If you lived somewhere that grew bananas, like south Florida, they did not taste sweet the way we would think of sweet. Apples were much less sweet, as were grapes. Even things you may not think of as a sweet, like potatoes and wheat, had a lot less sugar in them. Selective hybridization over the centuries has very purposely emphasized higher sugar content in crops.

In the 1970’s, the sugar industry gave three researchers $50,000 each to publish a paper that shifted blame from sugar to fat. One of the three, Mark Hegstead, would become head of nutrition at the USDA. He helped move the new food pyramid to include higher carbohydrate intake. This move by the sugar industry would have been much harder to pull off except Ancel Keys had published his book, Seven Countries Study, after researching his idea that a fatty diet caused his problems. His study to try to prove it failed to prove his idea. He then cut out two-thirds of the data (instead of 7 it was 22 countries) so it would prove his point, and published the book, and then bullied other professionals until it became widely adopted. Even more egregious than ignoring this data, he was involved in another study years earlier, Data from Minnesota Coronary Experiment. This study completely refuted his ideas thoroughly and so it sat dormant for 40 years until 2017. You can find the re-evaluation study in the research list on this site. These lies are the basis of the government’s food pyramid we were all taught.

For the last 50 years, we have been lied to. If you line up the graphs by date showing increasing obesity, increasing heart disease, diabetes, etc you will see them all sharply rising shortly after the new food pyramid came out.

Many of the people spreading the lies do not know they are wrong. Many of our doctors are merely teaching what they have been taught. Unfortunately, most of the doctors who do know the truth cannot do much about it because the Standard of Care to which the medical industry abides forces the lie to perpetuate under threat of law suits against doctors who go against it. I encourage everyone to research for themselves what is ancestrally appropriate eating and reduce their intake of the modern foods packed with chemicals and other unhealthy additives.

My Story

I have fought my weight ever since we miscarried Alex over 32 years ago. At the time, I did not correlate my excessive eating and sleeplessness with grief. Nor did I realize how addicted I had become to carbohydrates. After decades of trying various ketogenic, vegetarian, juicing, and the mainstay calorie restriction diets, I have learned all of them allowed my addiction to take over because I am a carbohydrate addict, a carboholic. The problem with this addiction is if you tell people that you are addicted, or if you just say you are watching your weight, they still try to push their ‘food’ on you. However, if you say you are a recovering alcoholic, they will help keep alcohol away. I became morbidly obese and unhealthy, developed high blood pressure, pre-diabetes, struggled with anxiety and depression, and so many other problems. When I was doing keto again over seven years ago, in 2017, I started getting multiple blood panel tests to prove its effectiveness. Then in 2018, my only son, Caleb, died at age 21. I fell off of keto shortly after that but I kept getting tested.

My PSA had been around 2.2 for several years. In October 2021, it was 2.6, not a concerning rise. Then in June 2022, the test showed my PSA had shot up to 3.8. I retested it a few weeks later to verify and it was 4.5! I was very concerned because this indicates a highly probable prostate cancer.

Scared, I scheduled a urology appointment and spent two days researching all the ways to beat cancer. I stumbled over a Reddit post saying they used the carnivore diet to beat cancer. I wish I kept that post reference. Not really knowing what this was, I searched for carnivore and found Jordan Peterson talking to Joe Rogan and his saying how much better he felt and his depression and anxiety was cured. More research that night, finding many anecdotal personal stories and cancer clinics that use low carb and fasting, I became convinced it could possibly slow cancer. If it did that, or removed the 80 pounds I gained since Caleb died, or even just stopped the depression and anxiety, that’s better than where I was. I was encouraged because one of the diets I had done in 2000, the Atkins Diet, was very similar.

I scheduled a urology visit and they confirmed an enlarged prostate and high PSA. The doctor, concerned that I likely had ‘a problem’, insisted I get a biopsy. I asked if there was any other way to confirm and he said no. That’s a lie, and one that would haunt me a few weeks later.

No exaggeration, I nearly died from my biopsy. The urologist cut an artery on the wall of the colon. He stopped the bleed, but then at home it resumed a few days. I went back to the urologist and it stopped bleeding on my way there. He said it probably needs a stitch if it won’t hold, but he didn’t want to disturb it, hoping it was fine. It resumed a few hours later and became so bad I went to the ER that afternoon. I sat there bleeding for seven hours before they called me to the back. They did a CT and the doctor said he would not touch an intestinal bleed and wouldn’t wake the on call colorectal doc. He sent me home and basically said return when I was dying. I texted my urologist and he responded with an appointment with a specialist for me first thing in the morning.

My joy was short-lived because I had another big expulsion of blood, got dizzy, sat down on the couch, and took my blood pressure. I had been monitoring it all day so I would know when I could go to the E.R. It failed to register any. I tried again. We tried my other arm and got a diastolic of 47. Donna put it on her arm and it worked. Yeah, this is not good. I got dizzy again and then nearly blacked out. Donna was yelling at me, trying to get me to respond. I could hear her faintly, but I could not respond. I then came to. My skin was cold and clammy, and my clothes were sopping wet from sweat. I was super scared!

I really did not want to go to the emergency room. They would just mess up my chance at seeing a real surgeon who does this for cancer patients and other tough cases all the time. We decided I needed sugar and electrolytes after drinking water all day. I drank two Gatorades and had a snack. Yes, I broke my diet for a medical emergency. I went to bed for a couple hours and thoroughly expected to not wake up.

Surgery went great. The biopsy results came back and it confirmed cancer likely. They tested the sample at another lab which agreed it was cancer, stage 1. The doctor scheduled an MRI to do surgery planning. Because I recently had colorectal surgery and a colorectal coil would be best, he delayed the MRI screening a few extra weeks. A glitch in the scheduling occurred and it was delayed another few weeks.

It wasn’t until about five months after I started carnivore when the MRI occurred and it found a normal sized, 31ml prostate and no cancer. A retest of my PSA showed it was lower than it had ever tested, 0.8!

Since starting this carnivore lifestyle, I have lost over 90 pounds of fat, gained a lot of muscle, turned my A1C from pre-diabetic 6.8 to 5.4 (well below any concern), blood pressure from 147/83 to 120/72, and triglyceride/HDL ratio is 1.1. My pants went from 44” to 32” in the waist. I am in the same pant size I had when I was 23! Pretty good for a 53 year old!

The weight loss is not the biggest win. While the cancer win is huge, it does not impact my daily life as much as the smaller things that have changed. After 30 years fighting to breathe, on 3 different medications everyday for 24 years, going to the doctor 2-3 times a year for steroids and antibiotics, I can now breathe freely with no medications! Keto never fixed this, but not eating plants 10 days did!

I tried to manage my anxiety and depression after Caleb died. It became bad enough that I went to a psychiatrist who prescribed an SSRI. I hated how I felt on that, tried getting the dosage adjusted, and then Covid hit. The doctor’s office was not allowing patients to come and I could only get refills of my current dose. Well, I weened myself off the SSRI. Within about three weeks of carnivore, I noticed my anxiety was greatly reduced and my depression more manageable. A few more weeks and they were both easily managed!

Before going carnivore, I could not walk up my stairs except using my left leg to step up, then bringing the right one up to the same step. Any attempt to put weight on the right knee was too painful. My orthopedic surgeon said I needed a knee replacement. A few weeks on the lifestyle and I could walk up my stairs. A few weeks more and I could do it with no pain. At month four I was walking the neighborhood and jogging some of the downhill portions. Month five I was jogging more. Then I started very short sprints. Now I sprint up each hill, no more than 15-20 seconds each time to not injure the knees. That is a massive mobility improvement! I might still need a replacement because the damage is done, but I can hold it off longer. The end of 2021, we went to an amusement park in north Florida. Obviously, it was extremely flat. It should have been an easy day of walking around and sitting. I could not walk around. I sat. If flat was not doable, thinking I could sprint uphill only two years later was unfathomable!

I eat no vegetables, nor fruits, nor spices. I have no condiments or sauces made with any of these things. I do not eat them because they affect my health. I feel worse when I eat them. Before changing to this lifestyle, I would use a lot. Now I can feel the difference. Because beef and eggs make me feel the best, that is 95% what I eat. Bacon, other meats, and a little cheese is the rest. My one remaining non-carnivore hold out is coffee. I tried quitting but my ADHD was much more difficult to handle. Taking Adderall or Focalin would let me say I am clean carnivore, but I think coffee is an acceptable trade to not take these powerful stimulants. I think I would feel better without coffee but my job performance would suffer. As it is, the ADHD is better on this lifestyle. It’s hard to explain the difference, but while I still need help and even then it is not great, my thinking is more focused with more clarity.

Cooking and making my own recipes was a passion of mine and I have enjoyed cooking professionally and at home. This lifestyle took most of that away. However, I no longer desire all those bells and whistles.

Nothing tastes as good as feeling great!

Cancer

Over the years, it has become a widely held belief that cancer is predominately a genetic disease or simply the consequence of bad luck. An empowering evolution in cancer research, however, suggests we have far more control over our risk than previously thought.

Dr. Seyfried has over 150 peer-reviewed publications, and his research focuses primarily on the mechanisms driving cancer, epilepsy, and neurodegenerative diseases and calorie-restricted ketogenic diets in their prevention and treatment.
