What changes the calories
- Tomatoes are mostly water, so cooking them down into sauce or paste concentrates the calories into a smaller weight.
- Roasting, frying or sautéing tomatoes in oil adds the calories of the oil used, which can easily outweigh the tomato itself.
- Sun-dried tomatoes, especially those packed in oil, are far more calorie-dense by weight than fresh tomatoes.
- Size varies a lot, from cherry tomatoes to large beefsteaks, so counting 'one tomato' can be off unless you check the size.
Tips for logging it accurately
- Weigh tomatoes on a kitchen scale, or use the closest serving size such as 1 medium slice (20 g) or 1 cup chopped (180 g).
- Log fresh tomatoes as raw, and log any dressing, oil, cheese or salt-based toppings as separate items since they usually add more calories than the tomato.
- In BerryFit, you can snap a photo of a salad or sandwich to log the tomatoes alongside the other ingredients, then adjust portions if needed.
