Nutrition data and methodology
Nutrition values are based on the official McDonald’s Slovenia Big Mac page, which lists 503 kcal per serving and 232 kcal per 100 g. The approximate 217 g burger weight is calculated from those two published calorie values.
McDonald’s states that its nutrition data are based on average values from European suppliers and that portions, preparation, ingredients, regional differences, seasonal differences, and product changes can affect the values.
