Banana nut muffins may contain healthy fruit, but these bakery treats also have plenty of added sugar and fat, making them rich in calories. Reserve this food for rare occasions, and try to eat just half of a muffin when you do indulge. If you make your muffins at home, you can lighten the calorie load by using less sugar and substituting an equal amount of applesauce for butter in the recipe.
