What changes the calories
- Roasting or sautéing fennel in oil or butter adds the calories of the fat it absorbs, which can easily exceed the calories of the fennel itself.
- Cooking drives off water, so a cooked portion weighs less than the raw fennel it came from and has more calories per gram.
- Trimming the stalks and fronds changes the weight you end up eating, so weigh the part you actually use.
- Creamy dressings, cheese or gratin-style toppings often add far more calories than the fennel in the dish.
Tips for logging it accurately
- Weigh fennel raw after trimming and log it as raw bulb, then add any oil or butter used in cooking as a separate entry.
- If you only have a volume measure, use 1 cup sliced (87 g, 27 calories) as your reference for salads and slaws.
- In BerryFit, snap a photo of your fennel dish to log it quickly, then check the portion size and add any dressing or cheese.
