The food from your favorite Chinese restaurant probably contains a reasonably low amount of saturated and trans fat, but likely, it will provide you with a larger number of calories, says the Center for Science in the Public Interest. Ordering vegetable lo mein will help keep your caloric intake in check. Serving sizes at most Chinese restaurants are large, so taking half home for a second meal will also help you curb your caloric intake.
One 741-gram serving of basic vegetable lo mein has 897 calories. About 596 of the calories in one serving come from carbohydrates, 140 from protein and 153 from fat, according to the U.S. Department of Agriculture's National Nutrient Database for Standard Reference. This caloric count may vary, depending on the serving size and type of meat, if any, included in the dish. If you add meat to the dish, it will have more calories, protein and fat. One serving of lo mein in combination with meats such as beef, chicken, pork or shrimp can have as many as 1,100 calories, according to the Center for Science in the Public Interest.
