I don’t know what you’re trying to achieve, but my goals are to improve my insulin sensitivity, decrease body fat, and improve cognitive function. Prolonged fasting is the most efficient means of accomplishing this. I didn’t feel comfortable embarking on a several month fast without medical supervision. And I didn’t want fasting to be at the front and center of my life and of those around me. I call it OMAW. Most days I’m fasting, but I eat when it’s socially expected. Over the past 5 months, I’ve gone 4-10 days before " pausing" my fast with a single meal, usually dinner.
I maintain a state of therapeutic level (3+ mmol) ketosis. Eating a meal may increase my BG (especially if it’s not LC) for a day, but will not take me out of ketosis. Weight loss has been consistent (no stalls), I’m down 65 lbs, with no loss of muscle mass on DEXA.
I don’t know if there are any advantages to an uninterrupted prolonged fast vs OMAW. But it’s working good enough for me.
