                                The calorie count of a blueberry muffin can vary dramatically, with some coffee shop muffins containing upwards of 450 calories, according to Harvard's T.H. Chan School of Public Health. This vast range is primarily influenced by the muffin's size, ingredients, and preparation method, highlighting the need for a closer look at what you're actually consuming.
