What changes the calories
- The figures here are for peeled lemon flesh, so a whole lemon with its peel weighs more than the edible part you actually eat or squeeze.
- Lemon juice alone leaves behind much of the pulp and fiber, so a squeeze of juice is generally a bit lighter than eating the same lemon's sections.
- Sweetened lemon drinks, lemon curd or candied peel add the calories of the sugar used, which can far outweigh the lemon itself.
- Lemons vary a lot in size, so a large lemon (84 g, 24 calories) is noticeably more than a medium one.
Tips for logging it accurately
- For a wedge or slice squeezed over food or into water, log 1 wedge or slice (2 calories); it rarely needs more precision than that.
- If you use lemon in larger amounts, such as sections in a salad, weigh the peeled flesh and log it by grams for accuracy.
- Log any sugar, honey or oil you combine with lemon as separate entries, or snap a photo of the finished dish in BerryFit to capture everything together.
