At the time, I used MyFitnessPal to Fitbit (or possibly Jawbone, may it rest in peace) to IFTTT to Beeminder to get the data as an autodata goal. IFTTT would send a 1 every time I logged a meal in MFP.
Unfortunately, I can no longer find those triggers in IFTTT with Fitbit, so that particular autodata path isn’t working for me anymore.
Curious, why do you want to track separate meals instead of total calories or something else?
If you want to beemind entering data in myfitnesspal you can simply track calories with a rate of your average intake.
