How many calories in a bag of Pop Secret Homestyle popcorn popped?

Pop Secret Homestyle microwave popcorn is a popular snack food. Many people enjoy popcorn as a tasty, low calorie snack. However, the number of calories can quickly add up if you eat an entire bag of popcorn in one sitting. Knowing the calorie count per bag is important for people monitoring their calorie intake.

The number of calories in a bag of Pop Secret Homestyle popcorn depends on the size of the bag. Pop Secret sells Homestyle popcorn in three sizes: individual snack size bags (2.5 oz), medium bags (10.5 oz), and family size bags (18 oz). The calorie count increases with the bag size.

Calories per Serving

According to the Pop Secret website, the calorie count per serving of Pop Secret Homestyle popcorn is:

Serving Size Calories
2.5 oz (Individual bag) 110 calories

18 oz (Family size) 810 calories

The individual snack size bag contains 110 calories per serving. The medium bag has 460 calories per serving. The family size bag contains 810 calories per serving.

Keep in mind the calorie count on the Pop Secret website is based on one serving size. The snack size bag is one serving, but many people eat the entire medium or family size bag which contains multiple servings.

Calories for Entire Bag

If you eat the entire bag of popcorn, the total calories are:

Bag Size Total Calories
2.5 oz 110 calories
10.5 oz 460 calories

The calorie count for the whole snack size bag is 110 calories.

For the medium 10.5 oz bag, the total calories if you eat the entire bag is 460 calories.

The family size 18 oz bag of Pop Secret Homestyle popcorn contains 810 calories if you eat the whole bag.

As you can see, the calorie count jumps significantly as the bag size increases. Even though popcorn is low in calories by volume, it adds up quickly when you eat an entire bag.

Reasons Calories Increase with Bag Size

There are a few reasons why the calorie count increases dramatically with larger bag sizes of popcorn:

More Servings

Larger bags contain more servings per bag. For example, the medium 10.5 oz bag contains approximately 4 servings while the family size 18 oz bag has about 7 servings. If you eat the entire bag, you’re consuming 4-7 servings in one sitting which means a lot more calories.

More Oil and Butter

Bigger bags mean there’s more room in the bag for oil and butter flavoring. Pop Secret uses canola and/or soybean oil along with real butter to flavor the popcorn. More oil and butter equals more calories per bag.

More Kernels

With bigger bag sizes, there are simply more popcorn kernels in each bag. More kernels equals more starch and carbohydrates when popped which results in more calories.

People Eat More from Bigger Packages

Research shows people unintentionally eat more from larger packages, even when they’re not hungry. This is known as the portion size effect. When served a larger portion, people tend to eat more regardless of serving size. With a giant bag of popcorn in front of you, it’s easy to mindlessly overeat.

Tips for Reducing Calories When Eating Popcorn

Here are some tips to cut calories when enjoying popcorn:

Stick to Snack Size Bags

Read Serving Sizes

Be aware of the serving size and number of servings per container. Remember the calorie count listed is usually for one serving, not the entire bag.

Split Large Bags

If you do buy a large bag, split it into smaller 100-200 calorie portions in snack size bags right away. Store extra servings out of sight.

Flavored or Plain

Opt for plain popcorn over flavored varieties to avoid extra oil, butter, and other calorie-boosting flavors. Season lightly with herbs, spices, or just a dash of salt.

Avoid Butter Topping

Buttered popcorn contains around double the calories vs air popped. Skip pouring on butter after microwaving to save calories.

Control Portions

Measure your portion into a bowl rather than eating straight from the bag. This helps you control portions and be more mindful of how much you’re eating.

Satisfy Cravings

If you’re craving a salty, crunchy snack, popcorn can satisfy the urge with less calories than other crunchy treats. Just keep portions in check.
