Muruku is the festive trap. The tin sits on the table, you walk past, you grab a piece, crunch crunch, you walk past again. Each 30g handful is 155 calories and you will do that handful five times in one afternoon without blinking.
Five casual handfuls is close to 800 calories of fried snack, more than a full meal, and you got zero satisfaction from it because you were watching TV. If you want muruku, put one handful on a small plate and close the tin lah.
