When my Ex lost all his weight (50kg) he explained to me that when he'd assessed what he was eating, he'd discovered that he was loading all his calories on his evening meal... ie, a couple of hours before he went to sleep.

I know you burn calories while you sleep, but it's nothing like the calories you burn when you're awake and semi-active.

Anyway, he explained to me that he lost it not only by lowering the overall calorie intake, but mostly by switching the order of things around: like the old adage, "Breakfast like a king, Lunch like a prince and Dinner like a pauper".

Worked well for him, and made massive improvements for me, too. Yes, we also combined it with lower calories, but switching the food order around made a massive improvement for both of us too.

First I'll say I don't think it matters much.I think total calories and nutrient content are more important. If you observe the eating patterns of cultures that have managed to not develop weight problems generally they eat more earlier in the day. I think eating breakfast is more important. Your metabolism takes a nosedive if you don't eat it.
