Be purposeful with your work calendar. Some things that work; front load your meetings in the morning if intermittent fasting, when you are heads down in interesting work, you are not thinking about eating. Recognise when you are most productive, I have a personal heuristic, “if it ain’t done by 1pm, is probably ain’t getting done“. I just run out of stream in the afternoons, probably linked to circadian rhythm and food schedule.
