Is it 100 calories per bag only if every last kernel gets popped? Cause I just ate a bag and there were maybe 20 unpopped kernels left. I’m thinking that means I can have a few potato chips 
You can 1/2 of a Pringles lite.
As a restricted eater myself, 1/2s count.
(P.S. that’s one chip not 1/2 a can)
You’d have to figure out how many kernels were originally in there to calculate what percentage of the bag 20 kernels represents. I’m guessing it won’t add up to the caloric equivalent of even a few chips, but then again, I also believe adults should eat what they feel like eating. 
Similar question. Does the 100 calories count the oil caked to the inside of the bag?
Dude you don’t suppose to eat that. It’s full polyunsaturated fats and other baddies. Or palm oil.
It’s just there for looks.
You pop the bag. Carefully open, not to burn your nose. Pour in large bowl. Add approx. a shaker of salt, melted real butter(whole stick) and Eat !
Then go weigh yourself. Happy dieting!!
Certainly. To gain the entire 100 calories you have to lick the bag then dissolve the remaining oil film in alcohol and shoot 'er down. Mmmm.
It’s called a Redenbacher martini.
There should be a factual answer though- are listed nutrition facts based on all of the container or usual amount obtained out of the container?
That’s a very common trick in the processed food industry to make stuff look less unhealthy than it actually is: State the nutritional data (calories, fats as a percentage of recommended daily allowance etc) not as per the entire package, but as per a “serving” - and the serving is then defined as a ridiculously small quantity of the food, much less than the typical consumer would eat in one go. But the serving size must be stated on the label. So read it, then weigh out how much (or little) that is.
Single serving container in this case.
You do know there’s actual rules about what goes on the Nutrition Facts label:
https://www.fda.gov/consumers/consumer-updates/food-serving-sizes-have-reality-check
The FDA also changed the criteria for labeling based on package size. With the updated requirements, more food products previously labeled as more than one serving are now required to be labeled as just one serving. Why? Because people are more likely to eat or drink the entire container or item in one sitting. Examples include a 20-ounce can of soda, and a 15-ounce can of soup. And many large muffins that were previously labeled as two or even three servings will be labeled as a single serving under the updated requirements, consistent with how people generally consume them.
Certain larger packages that may be consumed either in one sitting or more than one sitting—depending on your appetite and inclination—must now be labeled both per serving and per package. This dual-column format is required if a package contains at least two times the reference amount customarily consumed (on which the serving size is based) and less than or equal to three times the reference amount. Some examples are a 19-ounce can of soup and 3-ounce bag of chips.
There is a loophole, but a relatively minor one:
For packages that are clearly larger than most people would eat in one sitting—one that has more than three servings—the dual column is not required. Manufacturers are only required in these cases to label these products per serving. Examples include a “party size” bag of chips or a two-liter bottle of soda.
I doubt a 100 calorie bag of popcorn would qualify. Even if the food manufacturers stamped their little feet really, really hard.

Then the entire content constitutes one “serving”, and the nutritional facts will be those that apply if you eat all of it in one go. But remember that under FDA rules, a packaged product must be sold as a single-serving unit if it contains less than 200% of the daily reference amount. So even with a single-serving product, you might still be eating way more than what would be good for you.
Not my question.
If it is known that on average say 10% of the kernels won’t pop (or 5% of the product will be stuck in the package) as typically used according to directions then are nutrition content figures based on the complete amount in the package, or the amount that will typically be consumable from the package?
There likely is a rule about that.
(g) The declaration shall accurately reveal the quantity of food in the package exclusive of wrappers and other material packed therewith: Provided, That in the case of foods packed in containers designed to deliver the food under pressure, the declaration shall state the net quantity of the contents that will be expelled when the instructions for use as shown on the container are followed. The propellant is included in the net quantity declaration.
So I’d say it’s the food in the package, not the effectively usable quantity of food in the package. But I’m not an expert on this.
Thanks.
People think calorimetry and nutrition are very exact. Not so much, some of the precision is artifactusl. Food behaves differently (gawsp!) when consumed by a person versus being burned in a box.
It isn’t uncommon for the body not to absorb, say, 20-40% of a potential nutrient; bioavailability varies by source. Gotta feed the microbiome and make (in medical terms) chunky fudge. But I think the claimed calories includes all the oil and kernels, but itself could easily vary 10% or more from bag to bag.
This thread convinced me to go down stairs and make myself a “100 calorie” bag of Pop-Secret popped corn. While I was there I took a look at the nutrition label and found a two column nutrition label shown in this link (scroll down)
So for this brand at least, they recognize a difference between the contents of the bag (120 cal) and the result of popping (100 cal). If your brand is similar then I’m afraid you don’t get your chips (you can’t eat just one).
Another fun one: make the serving size so small that rounding rules come into play. Tic-tacs are claimed to have 0 grams of sugar, even though they’re almost entirely sugar, because they weigh half a gram and that rounds down to 0.
Does it also list your dosage of PFAS?

Here is what my box of Orville Redenbacher’s Movie Theater Butter says.
Serving size 2tbsp (35g) unpopped. (Makes about 5.5 cups popped).
1 cup popped = 30 calories.
2.5 servings per bag.
170 calories per serving.
That spells it out despite using three different units of measure for the popcorn.
Another tactic is to use different types of sugar so they can be listed separately, so the major ingredient doesn’t appear to be sugar.
