                                According to official McDonald's nutritional data for the U.S., a small strawberry shake is the lowest-calorie option among standard flavors, containing 470 calories. This surprising fact reveals that the vanilla shake, often assumed to be the lightest, is not always the best choice for a sweet treat with fewer calories.
