i lost 30kg within a year and tried different things before and after, and eating a lot of calories in the morning was the only thing I could stick to. and it wasn't a particularly good diet either. I started almost every morning with a donut and a chocolate croissant, along with a coffee, picked up from my favorite bakery. In case you're wondering how I lost any weight at all: I exercised about an hour 6 days a week. I would have no or only a small lunch, and then a decent sized (though still less calories than the breakfast) dinner. It seems the exercise was the key here, but I tried the same thing with different eating schedules after, and it just doesn't work. currently for example I'm arguably doing more exercise hours, just less intense (because I picked up climbing), but because there's free lunch at work and it's sort of a social pressure thing to take part, I can't seem to lose weight (I gained back about 10kg due to moving countries and being lazy). In particular I am very hungry in the morning and towards lunch, making me eat more than I probably would otherwise, and then I get absolutely insane cravings that disable any sort of objective reasoning apparatus in my head towards the end of the night. These studies probably have a hard time controlling for psychological aspects. Just being watched in your diet and knowing you took part in a study is bound to have some effect on how people stick to it.
