Finally, after five months of eating a high-carbohydrate, low-fat diet, I have some blood test results to share.
If you’re just finding me, I ate a carnivore diet for three and a half years, and then five months ago (October 2025), I switched to a high-carbohydrate, low-fat diet. I shared my reasons for the change in another video, which I’ll link here if you want to check it out.
But basically, I was worried about my metabolic health. My blood test results were showing that things might have been going in the wrong direction. I wasn’t losing weight, and after three and a half years, I was getting really frustrated. So I decided to try something different.
I recently made a video sharing an update on my current diet and what has been happening. In that video, I mentioned that I’d made a mistake when I had my last lot of blood tests done in August 2025. It’s now March 2026 at the time of writing.
Back in August last year, I had a lipid panel, along with fasting glucose and insulin. I’m not exactly sure what happened, but everything I’d been researching got a bit muddled in my head, and somehow, I basically forgot that I’d had the lipid panel done.
It might have been because the insulin results take about a week to come back. The rest of the blood tests come back within about 24 hours, but the insulin test takes about 5 days. In between the test results arriving, I was undoubtedly digging into a lot of information. When the insulin results arrived, I calculated my HOMA-IR—which I hadn’t done before—and kinda panicked, thinking “Everything’s going in the wrong direction!”
A Faulty HOMA-IR Calculation…
When I calculated my HOMA-IR back then, it was 4.16, indicating severe insulin resistance. That was when I started thinking seriously about changing my diet, and in October I made the switch.
However, today I realised that I made a mistake with that calculation. My HOMA-IR wasn’t 4.16 at all. It was 3.6. So it wasn’t quite as bad as I thought, but it was still a problem.
And if I’d also focused on the lipid panel and looked at my triglyceride results at the time, I might have realised that I probably didn’t have lipotoxicity as I thought I did, and that things might not have been quite as bad as I believed.
Doh!….
But even though I made some stupid mistakes that led me to change my diet, I’m not unhappy that I did this experiment. I’ve learned a lot from it, and there have been some interesting changes in my body—especially in how my body manages glucose.
Another big change has been my bowel health. If you’ve followed my journey at all, you’ll know my IBS diarrhea story already. But in case you’ve not heard my story, the short version is that I had decades of chronic diarrhea that worsened on a carnivore diet and never really went away. I was still having episodes off and on right up until I changed my diet in October.
However, since changing my diet, I’ve had zero diarrhea.
For me, that’s been a huge learning experience because it suggests that my digestive system is happier with some fibre. I suspected that even during my carnivore journey. The diarrhea was always better when I included some fibre, like blueberries.
So this experience has really reinforced that fibre may be important for me, at least right now. My body is still healing, so I don’t know what the future will look like, but at the moment, fibre seems important for me.
Now, enough of that. Let’s get into the blood test results.
