Canton noodles are flour and egg noodles that have already been fried once at the factory, which is why they are 350 calories per 100g dry compared to 360 for bihon but with three times the fat. Then the cook adds a tablespoon of oil to the wok, sometimes two. A standard plate ends up with 17g of fat, most of it from the noodle and the pan rather than the pork.
The fiesta bilao is the version that catches people. A large bilao is about 3kg of pancit for 900 to 1,200 pesos and gets cut into 10 to 12 portions, so each is 250 to 300g. Except nobody takes one slice at a birthday, they take one, then a second because it is there. Two bilao portions with a slice of lechon and rice is a 1,300 calorie plate.
Instant pancit canton is its own category. A pack of Lucky Me Pancit Canton is listed at 280 to 290 calories on FatSecret, which is less than the carinderia plate because the pack is only 60g of noodles. The problem is the 1,000mg plus of sodium and the fact that one pack is never enough, so people cook two, which is 580.
