Number of calories in bun is one of the highest from all products in bread category. If you are on diet and you are looking for low-calorific bread, bun seems to be a bad choice. It is easy to find something better among other bread.

It is really much as for bread. Similar energy amount have only such products as pita bread, banana bread or hamburger buns.
