I’m tied up all weekend with work, so no time to post. Tons of interesting experiments coming up, though:

• Flour replacements: Just finished up testing of the last flour, so just need to test how much water each absorbs and write up. Very interesting results, some surprisingly good, some surprisingly bad.
• Allergy study: got great feedback on my proposed protocol, ready to finalize & pre-register and get going on the tests.
• BP & breathing: got great feedback on my proposed protocol, ready to finalize & pre-register and get going on the tests. I also have preliminary data from exploring different breathing protocols to hone in on the most impactful before starting.
• Commute studies: Got curious about how to speed up my commute and have been tracking time using different routes.

If I have time, I’ll post a little during the week so as not to build up a backlog, but at worst will resume next Saturday.

I posted initial results from testing of flour replacements this week. Of the 7 flours I’ve tested so far, all have been pretty good, with peak ∆BG of 16-29% of wheat flour by weight and 9-23% by volume (see post for details).

The post got a huge response, the most site visits and first-day comments on Reddit of any post so far. I’ve definitely hit on something people are interested in. From the comments, I also got tons of new flour replacements to try, almost double what I had found on my own.

Experiments this week focused on flour replacements and vinegar experiments. Next week will focus on continuing both of these, as well as figuring out protocols for some non-food studies I’d like to get going around breathing, blood pressure, and palm-cooling.

I posted the first phase of the vinegar study this week. Thanks  /u/genetastic and /u/kabong for all the work you put in figuring out the protocol, running the experiments, and analyzing the data! We successfully replicated the literature, seeing a statistically significant ~20% reduction in peak blood glucose and larger slowing of BG rise. The protocol I used, though, was extremely unpleasant (soak the bread in 30g ACV), so the next step will be to see if a more practical protocol gives similar results.

Experiments this week focused on flour replacements. So far I’ve tested almond, lupin, carbquick, carbalose, okara, and hemp. I’ll post a quick preview of the data next week after I’ve worked it up.

Next week will focus on more vinegar experiments, continuing the flour tests, and possibly starting alternate dietary fibers.

I posted the results for low-carb chocolates this week. Found quite a few good ones, most notably the high cocoa stone ground chocolate from Taza and allulose-sweetened dark chocolate from Trendz. On the scientific side, I got even more evidence that there’s a large variation in the impact of different fibers, even ones with the same name listed on the nutrition label. I’m going to see whether I can source a decent variety to test.

Experiments this week focused on the last chocolates and samples of a low-carb chip under development by a food start-up (details and review to be provided when I’m allowed to post). Next week will focus on collecting more data for the vinegar study and starting to look at flour replacements and high-fiber fruits and vegetables.
