                                A standard 50g white hamburger bun contains approximately 135 calories, but this figure can change dramatically based on the type of bun, its ingredients, and how it was prepared. Understanding this variation is key for those tracking their caloric intake, as a bun's composition significantly influences its overall nutritional value.
