Calorie counts vary by product and serving size, but diet popcorn snacks commonly range from about 50 to 120 calories per serving.
Portion sizes span small single-serve pre-popped bags (about 0.46–0.88 oz) up to larger bags and multi-bag packs; some individual bags in the selection are as large as 16.2 ounces, depending on the product.
Many diet popcorn items highlight whole-grain or organic sourcing; some explicitly state 100% whole grain, certified gluten-free, or non-GMO organic popcorn.
You’ll find single ready-to-eat bags as well as multipacks; common counts include single bags and multipacks or boxes of 6, 10, 18, and 24.
Many pre-popped diet popcorns are air-popped for a lighter texture, while other products are microwaveable or sold unpopped to be popped at home.
