Vadai gets a bit of a free pass because it sounds healthy, lentils lah, whole spices, no sugar. And honestly 195 kcal per piece is not outrageous. But 70 of those calories are pure absorbed frying oil. That is more than a third of the entire piece just from oil. The lentil batter does bring some protein and a bit of fibre, so it is not completely empty, but calling this a light snack would be wishful thinking. One piece is fine. The problem is the mamak charges like RM1.50 per piece and they come out hot and crispy and before you know it you have eaten four of them.
The real variable here is how many pieces you eat and what you dip it in. Four dhal vadai straight up is 780 kcal. Add two generous scoops of coconut chutney at roughly 60 kcal each and you are sitting at 900 kcal for what felt like a light snack. Prawn vadai bumps each piece to 215 kcal because of the prawn on top but also adds a bit more protein, so if you are eating two pieces anyway the prawn version is not a bad trade. The other thing that changes the maths is whether you are eating this as a starter before a full nasi kandar plate or as a standalone. Standalone, two pieces at 390 kcal is a decent snack. As a starter before a big meal, you probably did not need them.
