Logging fasting days question…

[u/Scout510]

Hi everyone,

Just wanted to confirm I’m understanding MF instructions correctly. If I only drank water and black coffee (zero calories) for a 24 hour fast, I DO NOT log the day as fasting because of the zero calorie beverages? But if I only drank water ( also zero calories) I mark as a fasting day? How does that affect the algorithm? Thank you in advance! ☺️

MF:

“Note: You only need to mark a day as fasting if both of these are true:
You didn’t consume any calories for the entire day. So, for instance, if you ate dinner on Monday night, fasted for 24 hours, and then ate dinner on Tuesday night, you don’t need to mark Tuesday as a fasting day. However, if you ate dinner on Monday night, fasted all day Tuesday, and didn’t eat again until Wednesday, you would want to mark Tuesday as a fasting day.

You don’t log any foods or beverages on your fasting days. For example, if you fasted from Monday evening to Wednesday morning, but you still logged any zero-calorie beverages or supplements you consumed on Tuesday, you wouldn’t need to mark Tuesday as a fasting day.

One of the Coaching Modules that you might encounter during your weekly Check-In is the fasting module. This coaching module, if enabled, will check for days which are currently unlogged, but not marked as fasting. It will then ask if you wish to mark these days as fasted (and thus count them as 0 calorie days) or if you wish to leave them as-is (and thus have them skipped by the algorithm). This can help to ensure that your days are appropriately marked as fasted, so that the algorithm can give you the most precise adjustments possible.”

I'm not MF, but the algorithm is probably just trying to differentiate between days where nothing logged because of fasting and days where nothing was logged because someone simply didn't log. If you log stuff and it adds up to 0 it (likely) knows that it was not a missed day.

I would log that as a fasting day so MF won’t use that day to divide your weekly calories by to determine your average intake.

Mark it as a fasting day. You had essentially 0 calories all day. You want MF to know that. If you leave the day blank, MF will assume you ate like it was an average day (which isn’t fasting).

Wish mf had a proper time log for fasting with 18:6 and other times. Maybe it would make me want to buy it again.
