How Many Calories There Are in Dry and Cooked Products

It is believed that a person absorbs more calories not from raw, but from cooked food. At the same time, the calorie content of a certain product can change depending on how exactly you cook it. For example, if a regular egg is boiled, its calorie content won’t change much, but if you fry it, its calorie content will increase instantly. This information is not always on product packaging because manufacturers indicate the calorie content of products in the form they are in the package.

5-Minute Crafts is comparing the calorie content of regular products before and after they have been cooked.


100 g (3.5 oz) of fresh potatoes contain 93 kcal. This indicator can change as you cook this product. For example, boiling increases the calorie content of potatoes slightly. As for frying, potatoes absorb a part of the oil during the process and the calorie content can grow to 267 kcal.


Things are different with rice. The package normally indicates the calorie content of the dry product. If you take 100 g (3.5 oz) of dry rice, which contains 370 kcal, and boil it, it will result in decreasing the calorie content of this 100 g (3.5 oz) to 130 kcal. It happens because rice swells during cooking and increases in size and weight (but the calorie content of the product doesn’t actually change).

The situation with other groats is the same — they swell during the process of boiling and their weight grows, which is why 100 g (3.5 oz) of ready groats will have fewer calories than 100 g (3.5 oz) of dry ones.


The package of pasta also indicates the calorie content of the dry product, which is about 371 kcal per 100 g (3.5 oz). If you boil them, just like rice, they will absorb water and become bigger and heavier. That’s why 100 g (3.5 oz) of cooked pasta will be about 158 kcal.


100 g (3.5 oz) of raw chicken fillet contains about 165 kcal. But if you fry it, the meat will absorb the oil and the calorie content will grow to 269 kcal per 100 g (3.5 oz). Boiled chicken contains much fewer calories. Things are almost the same when it comes to beef and pork. By the way, using a marinade can also increase the calorie content of cooked meat.

Sometimes it’s not about heat treatment — meat can change its calorie content as a result of salting. For example, 100 g (3.5 oz) of lightly salted salmon contains 254 kcal, while wild fresh salmon is almost 1.5 times less caloric.


The package on cereals indicates the calorie content without milk or yogurt, which cereals or muesli are normally complemented with. If you take 100 g (3.5 oz) of muesli, whose calorie content is about 400 kcal, and mix it with yogurt, then 100 g (3.5 oz) of the prepared breakfast can decline to about 150 kcal (it depends on the amount of yogurt and its calorie content).

Chicken eggs

100 g (3.5 oz) of fresh eggs contains about 143 kcal. This indicator slightly increases when eggs are boiled. When fried, the calorie content of 100 g (3.5 oz) of cooked fried eggs is more than 200 kcal.


100 g (3.5 oz) of fresh bananas contains less than 100 kcal, but even if you don’t cook anything from bananas and simply dry them in the sun, their calorie content increases — dried bananas contain 3.5 times more calories compared to fresh ones.
