Asam laksa is genuinely one of the smartest hawker bowls for someone watching their weight, and most people do not realise it. The broth is tamarind, fish, chilli and herbs. No coconut milk, almost no oil. The flaked mackerel gives you real protein. At around 330 calories for a big satisfying bowl, the numbers are great.
The only thing to watch is the prawn paste (hae ko) drizzled on top. It is tasty but salty and adds a little sugar. Not a calorie problem, just go easy if you are watching sodium. Otherwise, order this with a clear conscience bro.
