> Not my experience. I eat one meal a day and I don't really get work going before that meal (which is usually around noon).

Of course, you do what is best for you. But I recommend you do some research in the parasympathetic and sympathetic nervous systems and how these systems relate to fasting and energy expenditure/utilization based on the diurnal cycle.

For my IF schedule, I aim to maximize the efficiency of both. This results in my having only an evening meal. I.e. active and responsive during the day (fasting), relaxed and digesting during the evening (meal time) before sleep.
