The lifelong question, how many calories are in that? Can I eat this? Will it ruin my diet? The honest answer, not in moderation.

But calorie counting is an efficient way of losing weight and regulating your food intake. 

Due to the higher fiber levels in popcorn, it is lower in calorie count, and it is lower in energy density. Popcorn is considered as food that will aid in weight loss. Compared to potato chips, which is much higher in calories and fat.

However, having a jumbo sized portion in the cinema covered in butter? Will help your diet? Absolutely not.

Luckily, you can eat a large amount of air popcorn and consume relatively few calories. Due to the fact that it low in calories, many dieters believe popcorn is also low in carbohydrates.

But this isn’t the truth. Even on a low-carb diet, you can still enjoy a couple handfuls of popcorn without splurging.There are also health benefits of eating popcorn: It can help you lose weight due to the fiber amount within it. It can also help control blood sugar.

Due to the fact that popcorn is a whole grain, so it is full of minerals and vitamins. It can prevent against diseases and improve your eyesight.Having microwave popcorn has also been linked to several health issues.

It contains ‘diacetyl’, a chemical that gives microwave popcorn its buttery taste and aroma. 

Diacetyl has also been linked to severe and irreversible lung damage when inhaled in large quantities. Researchers found a link between long-term exposure and lung damage.

Healthy Options

Air Popcorn is a healthy whole food which is rich in antioxidants and low in calories. Air-popped popcorn with a light season, that is where you will lose the most weight.

This is due to the whole grain elements of popcorn.

Popcorn packs much more fiber per serving than whole-wheat bread, fewer calories too! In theory, a 100 gram bag of ‘bad’ popcorn contains between 424 and 557 calories. 

This is assuming that this popcorn is made out of oil Or butter. However, it is worth noting that a large portion of popcorn in the cinema contains

A whopping 880 calories with 100g of carbs. But let’s get to the good popcorn, the healthy popcorn with lower sodium levels. With multiple brands like Skinny Popcorn being a staple in diet culture.

Those brands are centered around being low calorie and high in fiber, however, the website defines the brand skinny as not as diet friendly but as ‘using the fewest, cleanest and simplest ingredients possible’.

Orville Redenbacher is the most popular popcorn brand in the states.

However, one bag of microwave popcorn contains 430 calories, 41g of carbs, 26g of fat and 6g of protein. As the staple go to popcorn for all Americans, the calorie amount isn’t completely shocking.

However, if you are consuming large amounts of this microwavable popcorn, in hopes to lose weight, I’d suggest using your calories on something else. The second most popular brand of popcorn is Diamonds Foods’ Pop Secret, or just Pop Secret to us Americans.

With the wider range of how much butter you want per package, you can also imagine the calories are much higher.

For a bag of home style microwave popcorn, you are looking at about 510 calories per bags. Pop Secret also contains 42 grams of carbs and 36 grams of fat.

The third most popular brand of popcorn is Popcorn Act II, another buttery popcorn that is centered around, well, being buttery popcorn.

The calorie count of Popcorn Act II is 325 per bag, 45 grams of carbs and 15 grams of fat. So, in theory, Popcorn Act II is the lowest in calorie out of the brands, so if you are looking for a lower calorie opinion, Popcorn Act II is your top choice!

If you are looking for lower calorie popcorn, I’d recommend brands like, Orville Redenbacher’s Skinnygirl Butter & Sea Salt microwave popcorn. Quinn Real Butter & Sea Salt Microwave Popcorn, Newman’s Own Touch of Butter is another lower calorie brand. Also, Angie’s boom chicka pop sweet and salty kettle corn.

The final brand and also the most well known is the SkinnyPop original popcorn. SkinnyPop being one of the most well known diet popcorn, with only 100 calories per six cups and 0 grams trans per serving, Non GMO, Gluten Free, No Artificial Ingredients, Dairy Free, Peanut and Tree Nut Free.

Also advertised as 94% fat free, so they are a guilt free snack! With flavors such as white cheddar, butter, aged up cheddar, sea salt and pepper, twist of lemon and my personal favorite sweet and salty!

Having a wide variety of flavor is ideal for a change in taste buds and healthy alternative to buttered popcorn.


To conclude, the amount of calories in a bag of popcorn will vary depending on which type of popcorn you buy.

For example, cinema based popcorn will always be the highest in calories due to the vast amount of both popcorn and butter, and the jumbo portions. However, an average microwave popcorn will have on average 450 calories per bag.

Compared to a bag of potato chips, there is similar amount of calories but much more product – you can’t share a bag of chips, but you can share a bag of popcorn!If you are watching your figure but still want to enjoy a packet of popcorn while watching a Movie.

There are lower calorie options like SkinnyPop which is designed as a lower calorie choice. They come in various sizes and flavor combinations, which is great!

If SkinnyPop isn’t for you, there are other options like Orville Redencacher’s Skinnygirl Butter & Sea Salt, Quinn Real Butter & Sea Salt and Newman’s Own Touch of Butter for example.

I know calorie counting is an efficient way of both losing weight and keeping an eye on your weight. But, please stay healthy with this and don’t under eat your recommended daily amount :).
