How Many Calories in a Hard Boiled Egg. Even though eggs are healthy, you should be mindful of the fat and calorie count of any food that you eat when you're trying to lose weight. According to the USDA, there are 5 grams of fat and 78 calories in a hard-boiled egg. Most of the fat in a hard boiled egg is contained in the yolk. The yolk provides about 55 calories worth of combined fat and protein. Egg whites, on the other hand, are packed with fat-free nutrition. You'll consume 4-5 grams of protein, just 17 calories and virtually no fat in a single large egg white.
