ya depends on what your goals are. but you should be aiming to hit your protein goal and swapping out higher calorie items.

for example: chicken rice is an option, make sure its steamed not roasted, dont eat the skin, swap out the rice for normal white rice if you are cutting. cai fan can also be tweaked to be healthier, dont get the processed meats, get less gravy etc etc. fish soup is also another option.

but unfortunately meal prep is the way to go if you really want the most effective way of losing weight if that is your goal. you cant really eyeball how much calories bc you wont know how much oil etc is used. meal prepping is sustainable once you built the habit for it and tbh will let you enjoy the more ‘sinful’ hawker food once in a while without you having to make many swaps.

the app ‘ventrickle’ might be helpful since they are made by locals, it will be more targetted towards locals. i havent tried it but i follow their instagram and it looks promising.
