I go for evening personally. Eating early tends to make me hungry later. I've gotten used to putting in long hours doing sometimes arduous work from 7:30-6:00 and sometimes later. When possible a lunchtime pickup game of basketball. If I'm not exhausted when I get home a single heavy set of deadlifts, squats, cleans or chin ups then dinner. Sometimes sprints or stairs if I feel like it, I don't do all of this everyday of course. It's important to pay attention to your body, rest when needed and push yourself when you can. I feel like I'm getting both stronger and maintaining my bodyfat or actually losing if I focus on macro nutrients

I'm not sure if this is IF paleo appropriate, but I'm a huge fan of fasting whenever I feel like it. I eat when I'm hungry and stop when I'm full, and often that's once a day. I say its not very paleo because I'm sure way back when, our ancestors didn't have much choice as to when they ate.

I think its important to just really listen to our bodies and learn to become attune to what it needs. And its great that we can afford to, especially now while we live in a time where food of all kinds is available year round. I know my body wouldn't respond well to such scheduling, but I guess if people really need that sort of regimenting, then go for it. Good luck!
