Hi all! As mentioned by @Agaricus in his own post we have a small, fun group of folks that are exploring self-experimentation.
You're welcome to join! You can read more about the idea & motivation here: http://openhumansfoundation.org/DIYExperiments/
My upcoming plan is to test this question: "Does intermittent fasting work for me?"
Boring for you, but it matters to me! I've lost 10 BMI points and I'd like it to stick.
- Test between two conditions:
Condition A: only eat between 12pm-8pm
Condition B: have 300-400kcal breakfast
- Alternate every week, a total of 6 weeks: ABABAB
- Track "adherence" (sticking to plan) via diet logs (I've been using MyFitnessPal)
- Track "outcomes" via mood tracking, 1-button tracker (distracted/annoyed by cravings), weight logs (Withings scale)
What mood tracking is best?
I tried two different apps, Daylio and iMoodJournal. I scheduled an identical set of check-ins for both, 7 times a day (7:30am to 7:30pm, every two hours). Beyond this, I'm using the default settings.
Neither app has continuous data export (e.g. via API) but both have an easy export-to-CSV in an email to myself.
Daylio has timestamp problems. The time recorded for my mood records in Daylio were the scheduled time, not the time I actually checked in! I often miss my notifications (sometimes I only manage to check in once during the day!) -- more often than not, I'm not logging it when prompted.
iMoodJournal seems to work. I like that there's more granularity on mood (1-10), and I like the defaults for these. Timestamps are correct. I'm also curious about the tag features -- maybe I can do more with that.
It seems iMoodJournal is the winner -- but I'd love to hear other recommendations. One gotcha is that iMoodJournal tracks location, which I don't want/need. (You can turn it off and delete past location history, but be aware that it's on by default.)
One-button tracking hunger? I want to try using the 1-button tracker -- maybe when my thoughts are distracted by hunger/cravings? (Interestingly, a couple other DIY Experimenters had similar ideas for the button.)
Tags for hunger? maybe I can use iMoodJournal tags to track hunger.
Getting my diet log data. Diet logs are routine for me, I've been using MyFitnessPal for 18 months now (not paying the monthly fee; I'll buy an app, but not a subscription). I've seen an export tool on GitHub. IIRC it's a hack (log in & web scrape) but I'm OK with that.
I'll update with insights into my data collection efforts. Part of our goal here is to learn barriers and share tools that help others do similar things.
(One thing I did earlier today: figured out how to parse the Withings API data to get weight logs. Hopefully others can reuse what I learned.)
Hopefully I'll get the button soon and will start the experiment soon after.
