What changes the calories
- Bun size varies widely, and larger bakery, brioche or pretzel-style buns can weigh much more than a standard 44 g bun.
- Enriched buns made with butter, eggs or milk, such as brioche, usually have more fat and calories than a plain bun.
- Toasting a bun in butter or oil adds the calories of the fat it soaks up, while dry toasting adds essentially nothing.
- Seeded or sweetened buns can differ slightly from plain ones because of the added seeds or sugar.
Tips for logging it accurately
- Weigh your bun or check the package weight, since a larger bun can carry noticeably more calories than a standard one.
- Log the bun separately from the patty, cheese and sauces so each part of the burger is counted accurately.
- Snap a photo of your burger in BerryFit to log the meal quickly, then adjust the bun entry if your bun is bigger or smaller than standard.
