In today’s interview I get to speak with carnivore diet advocate, Amber O’Hearn.
We talk about her personal experience eating an all-meat diet for the last 9 years.
We get a chance to talk about how she went from eating a vegetarian (and even vegan) diet, across to a low carb then finally, a carnivore diet and why she has never looked back.
We also discuss some common concerns for women who are considering this way of eating.
If you know someone who is interested in learning more about:
- Why they could be having trouble losing weight
- Who is dealing with mental health, or autoimmune health, problems related to their diet
- Wants to hear a female experience on what happens when you only eat meat
Then this interview is for them.
I enjoyed this interview as I have a keen interest in this topic and have just successfully completed a 30-day long self-experiment of eating only meat myself. (Watch my daily vlogs on Youtube here)
After speaking with Amber I have a better understanding of how significant an impact a meat only diet can have on our mental health and female wellbeing too.
What we choose to eat affects everything – from our weight and our mood, to what we might not even be aware of.
Sometime we only don’t realise certain issues until we make a dietary change that simply makes us feel better.
Special thanks to Amber for joining me on the show.
Enjoy the episode!

[00:20] – Introducing Amber O’Hearn, a data scientist by profession, she has been researching and experimenting with the ketogenic and evolution-based diets since 1997 and has eaten nothing but meat since 2009.
[00:42] – Previously on our podcast, Dr Shawn Baker has talked about his experience with an all-meat diet for a year now. Amber has been eating this way for a lot longer! We discuss terminology. She explains why she prefers the term carnivorous and how calling this type of diet zero carb can be misleading as shellfish, liver or even some milk products all contain carbs.
[02:06] – Amber’s journey started in 1997 when, inspired by her weight gain issues, she started experimenting with different diets. She tried vegetarianism and veganism until her studies took her to St Petersburg in Russia. There, she abandoned her usual diet and by eating what the locals ate she found she lost some weight. Naturally, this raised some questions for her. Further investigation led Amber to the bookProtein Power by Dr’s Mary Eades and Michael R. Eades
[04:50] – Dr Eades’ advice worked. Amber explains how she maintained the low carb diet, continued her research and why she gradually switched to an all meat diet. After pregnancy, during which she ate some carbs and gained weight, the low carb diet wasn’t getting her where she wanted to be so she tried going carnivorous.
[07:48] – Interest in carnivorous diet has exploded recently and we see more people making the switch from ketogenic and low carb diets. Amber talks about her experience with the ketogenic diet. We discuss ketosis, macros and why people focus on the level of ketosis, which can be somewhat arbitrary. Dr Stephen Phinney has said the level is based on the point at which we start to see therapeutic results. It is important to have a well-formulated ketogenic diet focusing on outcomes. Amber explains we should be focusing on the health outcomes and ask ourselves if ketosis is necessary for your end goal?
[15:11] – Amber explains how, after switching to a carnivorous diet in 2009, she discovered she no longer needed the psychiatric medication she was prescribed for her mood disorder. She was diagnosed with major depressive disorder at the age of 20 and later re-diagnosed as having bipolar disorder type 2. She explained how the mental health condition was progressing and she suffered from terrible side-effects from the medication she was on.
BioHackers Lab Tip: Listen to Mikhaila Peterson also share her mental health benefits on a carnivore diet.
[18:29] – On low carb and ketogenic diets people focus on macros, which can be quite complicated. With the carnivorous diet you just eat until you are full and do not restrict food. This is something most women worry about when trying to achieve weight loss. Amber points out that it is quite important to select fatty cuts of meat in order to feel good and not run into energy problems. There is also debate around how much protein is acceptable for different goals such as fat loss etc…
BioHackers Lab Tip: Listen to Prof. Stuart Phillips recommended daily protein amount.
[23:00] – It seems people tend to take up the carnivorous diet predominantly for weight management. While, unfortunately, there are no clinical trials, the results people seem to be reporting include a relief from autoimmune related issues such as arthritis, asthma and even skin problems, as well as digestive issues (meats are easy to digest) like irritable bowel syndrome, Crohn’s or colitis.
[24:30] – Carnivorous diet can be a very good base for a basic elimination diet. By slowly reintroducing vegetables or other foods we can see how the body reacts and what causes problems for us. Amber explains how if there are no benefits to you that you can see from eliminating plants, there is no real reason you would need to, however, you don’t know how you will feel until you have tried it. We discuss how long it takes to adapt and see a difference/benefits for most people; as with most things, everyone responds differently.
[30:28] – Electrolytes, such as salt, potassium, and magnesium, in particular, are helpful with the keto flu when transitioning to a ketogenic diet. Amber suggests they might also be beneficial when transitioning to carnivorous from ketogenic. Could putting extra salt on your meat help with this?
BioHackers Lab Tip: Listen to Dr James DiNicolantonio explain the benefits of adding more salt to a low carb/keto diet.
[32:40] – When most women go on a diet they restrict themselves on food. Low carb nutritionist Emily Maguire talked more about the problem with women restricting protein and the gluconeogenesis issue in a previous episode. How does this figure in a carnivorous diet? Amber explains that protein causes an insulin response (the only thing that doesn’t is fat), which slows down ketogenesis. She believes this is not something we should fear will interfere with weight loss. Dr Ted Naiman actually highlights studies showing that higher protein levels (30-50%) show superior weight loss.
[35:30] – Amber explains a possible reason why people are often reporting the same level of ketosis reached with higher protein levels in carnivorous diet vs lower levels in ketogenic diet. (Here are three ways how to check your ketone levels)
[38:00] – Women’s energy demands increase when they are breastfeeding or pregnant, often resulting in cravings for carbs. Amber believes this is the body’s way of getting fat and explains we have evidence of nomadic societies doing without a lot of carbs during pregnancy. She shares her own experience breastfeeding on a carnivorous diet as well as children’s diets!
[45:28] – How does the carnivorous diet affect the menstrual cycle? Some people do experience changes in length or stability of their cycle, but these reported changes seem to be a bit idiosyncratic and no real pattern has emerged. Amber also talks about conditions such as PCOS and endometriosis.
[47:30] – Do many women put on more weight on a carnivorous diet? It does happen in cases where there was a long history of calorie restriction. Most of this is likely caused by tissue healing, i.e., denser bones, muscle building etc., but some of it can be fat gain. There are instances where people accepted that for the sake of health and in time saw that weight come off again. Amber mentions Kelly Hogan and her amazing story.
[50:46] – We talk about food intake. Amber shares how much she eats, what kind of protein she eats and finding a natural rhythm that works. Her routine is hunger based and she generally eats two meals a day, lunch and dinner. Gary explains he was less hungry on a meat diet and when making the switch people might notice their meal timings change. We also discuss different cuts of meat and the difference in preference between men and women.
[59:05] – In the carnivore community we see a lot of red meat but is there anyone who eats primarily seafood? Polls indicate that beef is often the top preference.
