I’m always looking for collaborators for future experiments. If you’re interested in collaborating on scientifically rigorous self-experiments with low-carb foods, supplements, or other health interventions, please let me know in the comments or via the contact form on the right.
I’ve migrated the site from Blogger to WordPress. WordPress gives me a ton more control over formatting and saves a lot of time I used to spend dealing with bugs in Blogger on copy/paste of links and resolution of photos. This is the first post written with the WordPress editor. Hope you all like the new formatting (I do). I’ll keep working on it, but let me know if there’s anything you’d particularly like to see.
On the food effect study, I posted the testing results for low-carb ice-cream this week. Lot’s of great recommendations for additional brands to test, which I’ll add to my testing queue.
Experiments focused on finishing up testing of low-carb breads. Almost all have a high blood glucose impact (40-60% of glucose based on area under the curve), but I found a few that have lower BG impact (Carb0naut, Base Culture, & LC Foods). I’m still waiting for the last two samples to come in. Depending on which day they show up, I may have to delay the report a week.
In the meantime, I’ve started testing “audience requests” from my previous posts, as well as some ingredients that have been showing up in some of the products (sacha inchi seeds, glycerin, various flour replacements).

Active & Planned Experiments
- Comprehensive Bloodwork
- Goal: Establish baseline for a broad range of biomarkers and check overall health
- Approach: WellnessFX Premium panel
- Status: Complete, need to write up.
- Blood Glucose Impact of Low-Carb Foods
- Goal: Determine blood glucose impact of low-carb foods, supplements, and ingredients
- Methods of Sleeping Longer
Let me know in the comments if there’s any other experiments you’d like to see.
Observations & Data
- Sleep
- Back up to target after poor sleep last week.
- Blood Glucose
- Numbers were high this week due to overeating one night. Should come down again next week.
- Other Blood
- Hemoglobin was the lowest I’ve seen yet, close to the bottom end of the normal range. Keeping an eye on this.
- Pulse continues to drop on both the Omron (resting) and Apple Watch (sleeping & awake).
- Blood pressure was very high this week, but I had woken up ~1.5h early due to excessive heat. Might try testing this daily for a while to see if there’s any interesting correlations with sleep…
- Body
- I was able to stabilize my weight last week by adding an extra 200 calories to breakfast and continuing to eat more for dinner. I’ve cut back on the dinner again to finish my weight loss, but nice to see I know how to stop it when the time comes.
- Interestingly, change in waist measurement flatlined the week I didn’t lose weight, suggesting that I’m not doing any body recomposition, just straight weight loss.
