What is the calorie content of a medium egg?

A medium egg typically contains around 70 to 80 calories, making 80 calories the most accurate representation of its calorie content. The calorie content of an egg largely comes from protein and fat, which are essential nutrients. Eggs are often considered a good source of high-quality protein, and the fat content also contributes to their overall calorie count.

Other choices do not align with the standard nutritional values for a medium egg. The lower options underestimate the actual calorie content, whereas the higher options overestimate it. Thus, the choice of 80 calories reflects the average energy value found in a medium egg, serving as a practical reference for nutritional information.
