The sample has serious flaws and is quite unrepresentative of the population:
>We examined a group of 16 healthy young men (age 23.6 ± 2.3 years) with a normal body mass index (22.5 ± 1.1 kg/m2)
Size, demographic, gender, and BMI are all seemingly within the same cohort. I have seen neurological studies with an n=8 be the predicates of clinical practice because that's what the patient population on the East coast is, but this could have been expanded.
When looking at the results section, it looks like the data lines up almost inversely. Where if you have a high calorie meal in the morning you'll burn more calories throughout the day whereas eating at night you'll burn more calories at night. But they didn't measure calorie consumption from 23:00 to 7:00 so we have no idea what the measured consumption is.
Maybe I'm naive, but every time I talk to one of my colleagues with a PhD in nutrition they constantly say the same recommendations: eat a diverse diet free of sugar, try to avoid salt and red meat, and get your fiber. Meal timing has been shown to be more for the mind that for your health, in that it doesn't matter when you eat, how much you eat, but you eat correctly. I'll get off my soap box now.
