My question after reading all this is this. Why in the world after riding their butt off would anyone want to eat Costco muffins when there are so many better choices out there ? When I used to eat muffins, theyre off my diet now , I would only eat freshly made ones cooked locally and eaten warm just out of the oven. Those made in chains like Costcos scared the dickens out of me once their labels were read. They are a real processed food of high order.
Even locally made muffins are a high calorie low nutrient food loaded with sugar, butter, white flour,some salt, and really dont belong in anyones diet, fat or not , except on rare occasion.
