Costco muffins are high in calories because they are made with refined flour, which has a high glycemic index. This means that the body breaks down the sugars in the flour more quickly, causing a spike in blood sugar levels.
The body then responds by releasing insulin, which can lead to weight gain. In addition, Costco muffins are often loaded with sugar and fat, which also contribute to their high calorie content.
So why are Costco muffins so high in calories? The simple answer is that they are made with refined flour, sugar, and fat. However, the true answer is a bit more complicated than that.
The refined flour used in Costco muffins has a high glycemic index, which means that it is broken down quickly by the body and causes a spike in blood sugar levels. In response to this spike, the body releases insulin, which can lead to weight gain. Additionally, the sugar and fat content of Costco muffins contribute to their high calorie count.
