Store bought muffins are huge, and full of sugar and calories. That makes them a dessert, a treat, an indulgence - at which point you might as well get something tasty like a doughnut instead. Bonus: the doughnut probably has less sugar anyway.
When faced with the choice between a store bought muffin and a donut, if you're looking for fewer calories, less sugar, and more deliciousness, you should probably choose the donut. https://t.co/xcfGZozpQS

Obesity specialist Yoni Freedhoff pointed this out in a tweet, and the numbers check out: at Dunkin Doughnuts, a chocolate frosted doughnut has 1170 kilojueles and 13 grams of sugar, while their blueberry muffin is 1925 kilojueles and 43 grams - that's three times the sugar. Dunkin Doughnuts offers a reduced fat muffin as well, but it's barely any different. (It's got 10 grams of fat instead of 15, but still far outweighs the doughnut at 1715kJ and 39g of sugar.)
The size of each treat contributes to the disparity: both are calorie-dense, but muffins can be huge. And if you think of them as healthy, consider that maybe you've been fooled. "'Bran', 'Blueberry', 'Oat', 'Flax' - these words infer health," says Freedhoff. "Personally, if I'm going to blow 500 calories on a treat, it damn well better be more delicious than a muffin."
