Carnivore diet

Beef chuck steak

Posted by Gary

Dear Reader,

Welcome to Yummy Lummy. Yummy Lummy is a blog for people who live alone and are keen to cook meals for one. If you’re part of a couple, I hope the recipes are adaptable for you, too.

I also share my opinions on topics others may (or may not) be interested in. With my recent change in diet (SAD→CSIRO TWD→LCHF), the blog’s emphasis is shifting to my opinion on some food and non-food-related topics. Comments are welcome, even if I disagree.

I cite most journal articles or books I’ve read and mentioned. You can see the citations at the bottom of the post.

You can skip the introduction and jump to the recipe if you don’t care to read my views.

Introduction

I hope you’ve had a good week.

My week was mostly enjoyable. I’m more mobile, and I’m able to exercise more. I attended a follow-up consultation with my surgeon, and he is delighted with my progress. He was complimentary of the physiotherapist I am attending.

What have I been watching?

Star Trek: The Next Generation  

Considering Kathleen’s generous gift of Patrick Stewart’s memoir, as I was listening, I developed an urge to rewatch TNG.

What have I been reading?

Blood biomarker profiles and exceptional longevity: comparison of centenarians and non-centenarians in a 35-year follow-up of the Swedish AMORIS cohort (Murata et al., 2023)  

The authors hoped to better understand ageing by comparing a set of biomarkers.

The authors sought to:

  1. describe and compare biomarker profiles at similar ages between 64 and 99 among individuals who become centenarians and shorter-lived peers,
  2. investigate the association between specific biomarker values and the chance of reaching age 100 and
  3. examine to what extent centenarians have homogenous biomarker profiles earlier in life.

Participants came from a study spanning 1985–1996 and were followed for up to 35 years.

The authors considered biomarkers of metabolism, inflammation, liver, renal, anaemia, and nutritional status.

One thousand two hundred and twenty-four participants (84.6% females) lived to their 100th birthday. There were 44,636 participants in the study.

Higher levels of total cholesterol and iron and lower levels of glucose, creatinine, uric acid, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, lactate dehydrogenase, and total iron-binding capacity were associated with reaching 100 years.

The authors suggest that genetic and possibly modifiable lifestyle factors reflected in these biomarker levels may affect longevity.

The paper describes an observational study and cannot make claims about causation.

Nevertheless, the author’s message for me is to maintain a low-carbohydrate, healthy fat, and no alcohol diet. Another key message from this paper is that longevity is not the be-all and end-all. I’d rather live well and die without lingering and suffering than live past 100 and be miserable.

Making It So: A Memoir by Sir Patrick Stewart

I’ve been enjoying Kathleen’s gift. So far, I’m up to Stewart’s period with the Royal Shakespeare Company. (Stewart, 2023)

It’s fascinating listening to Stewart’s adventures with the RSC. I was meant to read about half a dozen of Shakespeare’s works in high school. I never did. I was not a fan of English as a school subject. Of all the plays and books on the reading list, I only read one book. That was “The Chant of Jimmie Blacksmith”, written by Thomas Keneally and published in 1972. (Keneally, 1972)

I preferred reading non-fiction, especially biology or space travel. I barely passed humanities subject examinations in high school.

The total book will take more than 18 hours of listening. I’m about halfway through. I’ve been listening in the evenings.

Thanks, Kathleen, for this beautiful gift.

Today’s lunch

I bought some smoked New Zealand Pacific salmon for lunch and added it to scrambled eggs made with butter.

Recipe

The beef chuck is often regarded as a cheap and tough cut of meat. With beef and lamb becoming more expensive, cheaper cuts are becoming more desirable. The burden of the cost of living is especially true for people watching their pennies and keeping to a budget.

Equipment

  • Slow cooker
  • Air fryer
  • Gas torch

Ingredients

  • Beef chuck steaks — The two steaks (see photographs) cost $AUD12. I’ll get two meals from these steaks.
  • Iodised cooking salt — 1 tablespoon.
  • Tap water — ½ cup.
  • Salted butter

Instructions

  1. Place the meat, salt, and water into the cooking vessel.
  2. Slowly cook for eight hours on low heat.
  3. Remove the meat and place the beef on a tray and into the air fryer for 20 minutes at 160 °C (320 °F). An alternative to the air fryer is a frypan. I’d use a carbon steel or cast-iron frypan to sear the surfaces of the steak.
  4. For the air fryer choice, once out of the oven, place a lump of salted butter on top of the steak and melt it with a gas torch.
  5. Set aside some of the beef for dinner, put the rest into a container, and refrigerate. I will use the meat for lunches during the week.
  6. Filter the cooking liquor and add it to my perpetual master stock.
  7. Serve the beef with vegetables or eat them alone. If you’re following a carnivore diet, just the beef will be more than sufficient to satisfy your hunger. If you’re low-carbohydrate, healthy-fat eating, the meat and some plant-based “real foods” like avocado, leafy green leaves, olives, and tomatoes are a good combination. If you’re not concerned with carbohydrates, potato mash would go well with the beef. If you’re vegetarian or vegan, this beef won’t be suitable.
  8. Always give thanks to the Lord.
  9. Eat with whatever implements you prefer. Eating with your fingers is okay, in my opinion. Tonight, I used a steak knife and a fork.

Thoughts on the meal

Chuck steak has the beefy flavour of more expensive cuts like rump and scotch fillet (also known as ribeye in North America). The marbling gives the meat a rich, buttery flavour.

The melted and torched butter added a nutty flavour.

Slowly cooking the meat ensured tender muscle fibres, and the fat was nicely rendered.

Introduction 

🤏🥊 for the first of the month and the beginning of the Australian 2024 financial year. 

Dear Reader, 

Greetings from Canberra. I’ve enjoyed a good week. I hope yours was equally rewarding. 

I was fascinated this week by the number of people I work with who spent so much time on smart devices or at their computers trying to buy Taylor Swift concert tickets. I was at a meeting on Monday and sat next to someone I’d never met; she spent almost the entire time looking at her smartphone. When she succeeded, she squealed and exclaimed she’d paid nearly $1000 for the concert ticket. I immediately thought about how many beef short ribs I could buy for $1000. 

Apart from work, one of the avenues I’ve been exploring out of curiosity started with listening to Jordan Peterson’s “12 Rules for Life” after Gabe Maté’s “The Myth of Normal”. 

I went to YouTube to see if there were more insights into their thoughts on the human condition. The YouTube algorithm presented me Mikhaila Peterson, Jordan Peterson’s daughter. Mikhaila is a young woman who has adopted the Lion diet to manage her chronic health condition. She claims she is in remission and the best health of her life. Her father has also adopted the Lion diet to counter his health problems; likewise, he credits the diet to his excellent health. 

What followed was watching more YouTube videos about this way of eating and a growing fascination on my part. 

As far as I could find, there’s only one published study of the Carnivore diet: a self-reporting observational study. Follow-up commentary on that work has also been published[1, 2]. 

Lion diet and the Carnivore diet 

The Lion Diet and the Carnivore Diet are both restrictive diets that focus on eating only animal products. However, there are some differences between the two diets.

The Lion Diet

  • Only allows meat from ruminant animals, such as beef, lamb, bison, and goat.
  • It does not permit plant products, including fruits, vegetables, nuts, or seeds.
  • It may include salt and water.
  • It is often used as an elimination diet to identify food sensitivities.

The Carnivore Diet

  • The diet permits all types of meat, including ruminants, poultry, fish, and seafood.
  • It may also include eggs, dairy products, and animal-based fats.
  • It does not allow any plant products.
  • It claims to improve gut health, reduce inflammation, and boost energy levels.

Critics have raised some concerns:

Nutritional deficiencies: Both diets are restrictive and may not provide all the nutrients humans need. 

Digestive problems: Some people may experience constipation, diarrhoea, or bloating when they follow these diets.

Increased risk of heart disease: A high-fat diet, such as the Lion Diet or the Carnivore Diet, can increase the risk of heart disease.

Consulting a general practitioner is recommended before considering any diet. A GP can help assess individual risk factors and advise if the diet is your best option.

Unless they travel with freezers of meat, I guess people on the carnivore diet won’t be on any Mars expeditions, given its fresh meat and organs that contain enough vitamin C to prevent scurvy. 

Dear Reader, please note this is not medical advice. Please take a look at my medical disclaimer. 

I am writing about this because I am curious. I also note Katharine’s recent blog post on the Carnivore diet. Katharine is a retired medical practitioner from Scotland. She mainly writes about diabetes mellitus. I’ve been reading her blog for many years.  

Recipe 

I may not be embracing the Carnivore diet; however, tonight’s meal could be eaten by a carnivore san the vegetables. 😆

Equipment 

  • Pressure cooker 
  • Air fryer 

Ingredients 

  • Beef short rib fingers 
  • Bone broth 
  • Iodised salt 
  • Brussels sprouts 
  • Red cabbage 

Instructions 

  1. Put the beef and broth into the pressure cooker and close the lid. 
  2. Cook for 1 hour under pressure. 
  3. Allow the pressure to equalise naturally. 
  4. Remove the meat and place it on a cutting board. 
  5. Gently pat the surfaces of the beef with some paper towel to avoid the fatty liquid making a mess. 
  6. Place the cooking liquor through a sieve and store the filtered liquor in a jar in the refrigerator. 
  7. Pat the surface of the meat to absorb excess moisture and set one aside while placing the others in a vacuum bag and sealing it for use later. 
  8. Rub some butter onto the surface of the meat and cook in the air fryer for 5 minutes on each side at 220 °C. 
  9. Plate up the meat and vegetables. 
  10. Give thanks to the Lord. 
  11. Eat with a knife and fork while watching the football (The Dolphins play the Broncos tonight). 

Thoughts on the meal 

What’s not to like about beef short ribs? A quick high-temperature cook in the air fryer at the end gave the meat a nice crust for a bit of mouthfeel. 

Final thoughts 

Would you spend $1000 on concert tickets? 

Have you heard of the Carnivore diet? What do you think about it?
