you don't go catabolic overnight. That's broscience.
Correct.
I always find it amusing when guys believe BOTH (a) that you can "go catabolic" during 5-8 hours of sleeping, AND (b) that 16/8 hour intermittent fasting is beneficial. Isn't the contradiction obvious?
I guess some people are just not thinkers.
The window of time before catabolism truly kicks in is, in fact, amazingly long—something like 60-72 hours, according to most of the studies that have been done.
Yeah those studies weren't done on people with higher-than-average muscle mass due to training (= bodybuilders/fitness guys). So muscle wasting/catabolism would probably start sooner in the kind of people who populate this forum... but definitely not less than 30-40 hours.
Suck it up people. Hunger is the feeling of a burning furnace, own that s**t.

In response to the original question:
Personally I eat all my food (and do all my workouts) within six hours of bedtime. Mostly because (a) that's when my kids are sleeping, but also (b) because I'm a "night person" by nature—I get sleepy and lazy when it's daylight out—and (c) because I sleep best on a decently full stomach.
On workout days I regularly consume between 150 and 200 g of carbs, along with 100 to 150 g of protein, within 2-3 hours of going to sleep.
At bedtime, I usually eat 30-60 grams of almonds, brazil nuts, and/or peanuts.
I am about 7% bf right now, so there are clearly no issues of nighttime fat retention.
