+1 for that. I'm on OMAD throughout the week and have been since... yea also going on 20 years. Weekends I would usually be more lax depending on my work load, but through my 20s and most of my 30s I was in the 1k lb. club weighing ~180 lbs. (squat 405 lbs., dead 415 lbs., bench 305 lbs.). And I ran 2-3 times/week for a weekly total of 15-20 miles except when marathon training in which case it was at least 3x/week for totals of >30 miles. So yea it's very doable to be strong/healthy and eat once/day. I got into it because eating throughout the day just seemed to bog me down. Eat a bunch at night, recover and digest in sleep, rinse and repeat. I'd say only if you're a pro bodybuilder do you need to constantly be feeding yourself, and that's because you're wasting drugs if you're not constantly eating.
