My ordinary day when I’m not extended fasting is to get up around 7 am, have large cup of coffee with probably 1/3 cup of hwc in it (about 2 carbs, but probably close to 300 calories) then lunch at 12 pm and dinner around 6 pm. (I’d prefer to eat my big meal earlier but it just doesn’t work in my household.) I consider my coffee to be breakfast, but it’s negligible carbs.
Would you say my eating window is 6 hours, or 11?
