What changes the calories
- Heaped versus level spoonfuls make a real difference, because a rounded teaspoon holds noticeably more sugar than a level one.
- Sugar added to coffee, tea or cereal is easy to underestimate when it is poured straight from the bag or jar rather than measured.
- Packed or sifted sugar changes how much fits in a cup, so volume measures are less reliable than weighing.
- Sugar already in sauces, baked goods and drinks adds calories that are separate from any sugar you add yourself.
Tips for logging it accurately
- Weigh sugar on a kitchen scale when baking or cooking, since grams are more accurate than cups or spoons.
- Count each sugar cube, packet or teaspoon you add to drinks, and log them as you go so they are not forgotten later.
- In BerryFit, save your usual coffee or tea with its sugar as a single entry so it logs the same way every time.
