- 1.
Measure by the ounce (28g) rather than by the handful — it's easy to pour 2–3 servings without realizing it, adding 400+ calories quickly.
- 2.
Use chopped pecans as a topping rather than a mix-in: sprinkling 14g over oatmeal or salad adds crunch and ~97 calories without dominating the dish.
- 3.
Pre-portion into small snack bags or containers at the start of the week to avoid mindless overeating straight from the bag.
- 4.
Pair pecans with a high-volume, low-calorie food like apple slices or celery to make a more filling snack without dramatically increasing total calories.
- 5.
If you're tracking calories, weigh pecans on a kitchen scale — volume measurements like 'cups' can vary significantly depending on how tightly the nuts are packed.
