Important note: this is in the context of maximizing hypertrophy.
It’s ballpark; but it doesn’t help much to micromanage. It’s not limiting you in the gym.
It’s ballpark for my daily. If you’re training seriously, double it or better.
I like one meal a day; so 23 hours would be cool. You could go 47 hours and eat double (especially if you’re old), and you’ll waste a little muscle if you try to go 3 days.
Most people eat more than once a day though; that’s fine. But it is an indicator of metabolic flexibility if you can go longer.
