Generally would be taken to mean you had a meal at night then go to sleep. then the following day eat nothing and go to sleep. Eat normally when you wake.
Eating one meal a day even breakfast would be considered a 23-1 intermittent fasting schedule or something, but realistically you are in a fed postprandial state for several hours after the meal so there's some daylight between one meal a day and actual 24 hour fasts.
