Well, it's a fusion of different cultures, especially the main cultures of Malay, Indian and Chinese that live there. For example, you have staples like Nasi Lemak(which laughably got listed as one of the healthiest international breakfast foods by TIME), Char Kuey Teow(which is just really greasy fried noodles with cured meats and shellfish) and Roti Canai(a mamak staple, greasy flatbread that comes in all sorts of beetus flavours).... I'm Chinese so we get the 'shitlordiest' foods since we don't have much of that greasy or fried stuff, but even that's not enough to prevent our huge foodie culture from turning our community into obeasts too. I get your point about the quantity of the food. I mean, not so long ago, Nasi Lemak used to come in small, tiny packets that probably contained like half a handful of coconut rice in it? Nowadays, they have to come in beetus sizes with extras like fried eggs and curried meats or people would complain.
