- 1.
Stick to a 1 oz (28g) portion — pre-weigh servings into small bags or containers at the start of the week to avoid mindless overeating straight from the bag.
- 2.
Use hazelnuts as a topping rather than a snack on their own — a tablespoon of chopped hazelnuts (~10g, ~63 cal) adds flavor and crunch to oatmeal or yogurt without a big calorie hit.
- 3.
Pair a small portion of hazelnuts with a high-volume, low-calorie food like fruit or raw vegetables to build a more filling snack for fewer total calories.
- 4.
Whole kernels take longer to eat than chopped or ground hazelnuts — choosing whole nuts naturally slows your pace and helps with portion awareness.
- 5.
Track by weight, not by count — hazelnut sizes vary, so a kitchen scale gives you a far more accurate calorie estimate than counting kernels.
