Two large eggs contain approximately 150 to 160 calories in total, with one large egg averaging around 75 to 80 calories. The calorie count can vary slightly depending on the egg size, with medium eggs having about 63 calories each and extra-large eggs around 90 calories each. Most of these calories come from fats and proteins, with eggs providing roughly 5 grams of fat and 6.5 to 7 grams of protein per large egg. Cooking methods like frying or scrambling with added ingredients can increase the calorie content significantly. For plain, cooked eggs, the calories remain close to the raw values, about 150-160 for two large eggs. This makes eggs a nutrient-dense food high in protein and essential vitamins.
