I think this depends on the place one is born and its corresponding culture. My mom is Dutch and they always eat their biggest meal at dinner. Luckily, we live in Mexico now and here the biggest meal of the day is lunch. I say luckily because we all know now that it is much better to eat big at breakfast and lunch, when we still need energy for our daily activities, rather than at the end of the day when we are hardly going to need all that energy. On the other hand, having big dinners makes people wake up without hunger and skip breakfast, a very big metabolic mistake! So yes, usually I have a good breakfast and a good lunch and at dinner I am not so hungry anymore, which means I eat a light meal then.
