What does each plate keep?
The photo, the date and time, which meal it was, the foods with their grams, and the read in a few plain sentences: how the carbohydrate arrived and what it came with. A few hours later your check-in joins it, so a plate in the diary is the whole of the meal, including the part you would otherwise forget: how it sat.
If you live with PCOS, now also called PMOS, you have probably been asked to keep a food diary at some point and found it a chore within a week. This one starts from a photo and fills itself in, and the days you skip are simply days you skipped.
