How many calories are in pasta?

Dry weight vs. cooked weight

A 100-gram (3.5 oz) portion of dry pasta weighs around 220 to 250 grams after cooking. Since no energy is added in the pot, the cooked portion contains exactly the same calories as the dry one — the per-100-gram figure just looks halved. For an accurate calorie count, weigh your pasta before cooking, or convert back from the cooked weight using a factor of 2.4 to 2.5.

Pasta and muscle growth

An 80-gram (2.8 oz) dry-weight portion of durum-wheat pasta provides around 57 grams of carbohydrate, making it a solid choice for refilling muscle glycogen stores after training. In its position stand on carbohydrate intake for strength athletes, the ISSN recommends 3 to 7 grams of carbohydrate per kilogram of body weight per day — depending on your body weight, a big plate of pasta can cover a quarter to a third of that.

Portion size

As a guideline for a main meal, the German Nutrition Society (DGE) suggests 60 to 80 grams (about 2–2.8 oz) of dry pasta, which yields 150 to 200 grams cooked. Restaurant portions of 250 to 350 grams of cooked pasta are common, which already means 400 to 550 calories from the noodles alone — before sauce, cheese, or sides.
