- 1.
Stick to a 1-oz (28g) portion — roughly 49 kernels — to keep calories around 157 while still getting a satisfying, fiber-rich snack.
- 2.
Buy pistachios in the shell. The extra time it takes to crack them slows your eating pace and naturally reduces how much you consume.
- 3.
Pre-portion pistachios into small bags or containers right after buying them so you're not tempted to eat straight from a large bag.
- 4.
Pair a 1-oz serving with a piece of fruit to add volume and water content to your snack, helping you feel fuller on fewer total calories.
- 5.
Track by weight rather than volume — a kitchen scale gives you accurate calorie counts, since cups can vary widely depending on how tightly the nuts are packed.
