for about 5+ years, 14-18 hours depending on the life / work. all that in parallel with powerlifting or powerlifting + MMA, so would go up and down in weight intentionally (up for strength / down for competitions). I hear you re: weekend and beers, and on those nights I would just start eating much later next day. Also if you miss occasionally one day every couple of months because you were out on a late dinner or date - no harm done. I still find it easy to keep a 13-hour window which I read is the minimum threshold for IF. Live a little. Turning IF into a religion makes it really hard to follow and a chore. Also if I feel hungry in the afternoon, but had my last meal later the night before, I would just find myself a task to complete (household chore, or an actual work task) or would go for a walk / go shopping, which provides a 1-3 hour fast extension.
