Hi spk,
You don't see many fat Thai/Chinese/Japanese people because most of their cooking is healthy....(Waits for everyone to scream " What about the curries!!!"
Seriously, I'm not talking about recipe dishes you buy in the supermarket (preservatives), but your own wholesome stir-fries. You do not need to use oil or fat if you don't want to..just a little stock or even water will cook your food....
Using fresh vegetables and meat (if your not a veggie)
is low in calories if cooked this way...
Remember though that the food you eat in most restaurants, is not always the food they eat themselves.
Just don't go frying the prawn crackers, egg(pancake) rolls,
crispy won ton, otherwise your defeating the object!!
