Calories in egg yolk vs egg white. Most of the calories in eggs, as well as all of the fat content, is in the yolk. The yolk from a large egg contains about 55 calories and just over 180 mg of cholesterol. An egg white contains 17 calories and no fat content at all.
One cooked egg white contains 17 calories. Cooked egg whites are a low-fat and cholesterol-free way to add protein and key nutrients to your diet. While many of the nutrients in eggs are concentrated in the yolk, eating just the white is a healthy option if you are following a low-cholesterol diet.
