The calorie content of noodles is not that high, and the calorie content will not increase further if you don't add oil.

Ordinary noodles: 284 calories/100 grams

Hanging noodles: 346 calories/100 grams

The exact amount of calories depends on how many noodles are boiled at a time. 600 calories is less than the amount of calories that would be consumed by a person who boils 2 taels of ordinary noodles, which is within the range of normal intake of calories.
