It should come as no surprise that doughnuts are off the menu for the 40-year-old. These delectable treats are no friend to your gut or metabolism. If you break down the doughnut, there is just no nutritional value at all. First, the dough is made from refined wheat, which affects your blood-sugar levels. Then, it’s dunked in vegetable oil and fried, adding to the already high-calorie count.

Then there is all the sugar. In the end, you are looking at close to 300 calories for a single doughnut. Even if you only have just one a day, you can still gain plenty of weight in a short period of time. They are also bad for your heart due to the refined nature of all the ingredients. The trans-fats from the oil it is fried in will increase your cholesterol and risk of heart disease.
