I would need to see some pretty incredible benefits to give up dinner over breakfast, that sounds miserable. I suppose if you’re someone who gets up at 5 and sleeps at 9 or 10 every night, then skipping dinner might be easier.
Also take into account your circadian rhythm. Humans have a variability of ~4h in our internal clocks, so when they eat lunch that might be breakfast for me.
If I eat dinner at 7pm and stay up until 2am (pretty normal for me), is that fine? Or did they toss me in with somebody who wakes up at 6am and goes to bed at 10pm, and thus only had maybe 2 hours between dinner and bed time?
