What changes the calories
- Shells are not eaten, so weighing chestnuts in the shell will overstate how much you actually ate.
- Roasting drives off water, so roasted chestnuts carry more calories per gram than fresh or boiled ones.
- Butter, oil, sugar or honey glazes added during or after roasting add their own calories on top of the chestnuts themselves.
- Chestnuts are easy to eat by the handful at markets and holidays, so a casual snack can easily reach 10 kernels (206 calories) or more.
Tips for logging it accurately
- Peel the chestnuts first, then weigh only the edible kernels for the most accurate entry.
- Log them as roasted chestnuts rather than raw or boiled, and add any butter, oil or sugar as separate items.
- In BerryFit, snap a photo of your peeled chestnuts and adjust the portion to match the kernel count or weight.
