Calories in cooked eggs

Two scrambled eggs cooked in the microwave with a little salt and pepper and a dash of semi-skimmed milk will provide around 170 calories. If you are cooking your scrambled eggs using the pan method, two large eggs with a dash of semi-skimmed milk scrambled with a small knob of butter will total between 200 and 245 calories depending on the amount of butter added.

Poached eggs are very popular as they don’t need you to add any extra cooking oil or butter to cook. This means poached egg calories equal the same as in the table above – between 54 and 80 calories depending on the size.

The calorie value of a fried egg will differ depending on the type of fat used in the pan and whether you drain it. It is often recommended to use oils which are rich in monounsaturates such as rapeseed or olive oil. A fried egg can range from 85 calories if using only a little spray-oil, to around 120 calories if frying in oil and not draining it.

Eggs and dieting

Scrambled eggs

Eggs are a great food to include in your diet if you’re trying to lose weight whilst ensuring your body gets all the essential nutrition it needs. Because eggs are nutritionally dense and contain fewer than 70 calories (medium-sized) they can be part of any calorie-controlled meals and snacks whilst still providing lots of protein and vital vitamins, minerals and fats.

The way you prepare your eggs will of course affect their nutritional value. For instance, if you fry an egg in fat, instead of boiling it, this will increase the number of overall calories. It is also important to eat your eggs along with other nutrient-rich foods, such as vegetables, salads and whole grains.
