Calories in dry oat flakes

100 g of rolled oat flakes has 352 kcal: 12.3 g of protein, 6.2 g of fat, 62 g of carbs and 6 g of fiber. A usual breakfast serving is 40-50 g of flakes, that is 141-176 kcal. A tablespoon of flakes weighs about 12 g and gives 42 kcal, a 200 ml glass holds about 90 g, which is 317 kcal. Quick oats and whole oat groats are almost the same in calories, the difference is cooking time.

Oatmeal with water and with milk

Water adds no calories, so porridge cooked in water weighs more but has the same calories as the dry flakes. 40 g of flakes and 160 ml of water make about 200 g of porridge, that is 141 kcal, or about 70 kcal per 100 g. If you cook it with 2.5% milk, a glass of milk adds another 104 kcal, and the serving comes to about 245 kcal, or 100 kcal per 100 g of porridge. Milk porridge is more filling thanks to the protein and fat of milk.

Sugar, honey, banana and nuts in porridge

Oatmeal calories usually grow from the toppings. A teaspoon of sugar is about 30 kcal, honey about 32, a 10 g piece of butter 75. Half a banana adds 58 kcal, a 20 g handful of nuts 120-130. Flavored instant oat sachets usually contain sugar, and one 35-40 g sachet comes to 130-160 kcal, almost like plain flakes, but keeps you full for less time.

Oatmeal for weight loss

Oatmeal is a good breakfast in a calorie deficit: a 40 g serving with water gives 141 kcal and almost 2.5 g of fiber, and oat beta-glucan makes the porridge thick and slows digestion. To stay full until lunch, add protein: a spoon of cottage cheese, an egg or Greek yogurt. It is worth weighing the flakes: they are light, and a couple of handfuls easily become 80-90 g.

How to count your serving

Weigh the dry flakes and multiply by 3.52, then count the milk and toppings separately. If the porridge is already in a bowl with fruit and nuts, take a photo in MyFoodMate AI: the app splits breakfast into foods and logs the calories.
