I didn't say "practical", I said "practicable".

I know at least one woman who is not naturally hungry in the AM, and she's a powerlifter. She relies on AM anorexia for calorie control, so she has available calories for after she trains, when she's hungry.

I don't need to eat very much during the daytime, but I'm FAMISHED at night. So I save daytime calories so I have extra to eat at bedtime.

It's how I was able to successfully diet down for the first time last summer.

Like I said, constrained optimization.
