How Many Calories Are In Starry? | Lemon-Lime Facts

Starry is PepsiCo’s citrus-forward lemon-lime soda that replaced Sierra Mist in early 2023. It comes in regular and Zero Sugar versions, both caffeine free. People reach for it because it tastes bright and crisp, not because they’re hunting for calories — but those calories still count. The numbers in Starry are mostly from added sugar, and that sugar stacks up faster than most people guess. The next sections walk through how many calories show up in a normal can, how fast that climbs with bigger bottles, and how that compares to daily sugar limits set by major heart-health groups.

How Many Calories In Starry Lemon-Lime Soda Per Can

A standard 12-fl-oz can of the regular lemon-lime Starry lists 150 calories, 39 grams of total sugar (all of it added), and 35 milligrams of sodium. A 16.9-fl-oz bottle jumps to about 210 calories. A 20-fl-oz bottle lands around 240 calories and 65 grams of sugar. Starry Zero Sugar, which uses no sugar, comes in at 0 calories. Those values come straight from the nutrition panels printed on Starry cans and bottles sold in the U.S.

Starry Calories And Sugar By Size

Serving Size / Product	Calories Per Serving	Added Sugar (g)
Starry, 12 fl oz can	150 kcal	39 g
Starry, 16.9 fl oz bottle	210 kcal	55 g
Starry, 20 fl oz bottle	240 kcal	65 g
Starry Zero Sugar, 12 fl oz can	0 kcal	0 g

Regular lemon-lime soda, Starry included, is basically sweetened carbonated water. The sugar is where almost all the calories live. You can see the pattern: more fluid ounces just means more sweetened liquid, which means more sugar and more calories. That sugar load lines up with what you see in many mainstream soft drinks, and you can compare it with the broader sugar in soft drinks chart on this site if you’re sizing it up next to cola or energy drinks.

Why Size Changes The Number

Soft drink labels treat the full container as “one serving” for common retail sizes like a 12-fl-oz can or a 20-fl-oz bottle. That means a single bottle can quietly bring in what some people think of as “two drinks,” even though the panel treats the whole bottle as one sitting. With Starry, that jump from 150 calories in a can to 240 calories in a 20-ounce bottle comes down to simple volume math. The soda recipe doesn’t suddenly get heavier in sugar; you’re just drinking more of it in one go.

What Counts As One Serving Of Starry

Label Serving Versus Real-World Pour

On a multi-can fridge pack, the nutrition panel often shows “Serving Size: 12 fl oz (360 mL)” and “Servings Per Container: 12,” because the case holds twelve cans. Each single can is still treated as the serving. With bottles, you’ll usually see “Serving Size: 1 bottle.” In practice, plenty of people pour part of a bottle over ice, sip, and leave the rest in the fridge. Others crack the cap and finish the whole thing while gaming or sitting in traffic. The label can’t guess which habit you have, so it lists the whole bottle as the serving.

Liquid Calories Sneak In Fast

Liquid sugar offers fast flavor and no chewing time. There’s no fiber to slow it down. You don’t feel full in the same way you might after eating something with protein and fat. That’s why it’s easy to drink 200+ calories without thinking. With Starry, that means you could take in the calorie load of a snack without ever calling it a snack. Many people only notice the hit when they track drinks inside a calorie log for a few days.

Does Starry Zero Sugar Change The Math

Starry Zero Sugar is the no-calorie version in the same lemon-lime line. The can lists 0 calories, 0 grams of total sugar, and the same caffeine-free profile. Instead of high fructose corn syrup, it uses high-intensity sweeteners so it still tastes sweet. Because there’s no added sugar, Starry Zero Sugar skips the sugar calories that drive the numbers in the regular soda. For people counting calories or grams of sugar, swapping even one regular can for a Zero Sugar can makes a large swing in daily totals.

Sodium And Caffeine Notes

Both Starry and Starry Zero Sugar sit in the low-sodium range for soft drinks. You’ll usually see about 35 milligrams of sodium in a 12-fl-oz can of regular Starry and a similar range in the no-calorie version. The drink is caffeine free, so you’re not getting a stimulant kick the way you would with many colas or energy drinks. There is one callout on Starry Zero Sugar for people with phenylketonuria (PKU): the label mentions phenylalanine, because the sweetener blend includes aspartame. That warning shows up on a lot of diet sodas in the U.S., and Starry Zero Sugar follows the same pattern.

Where Those Starry Calories Come From

High Fructose Corn Syrup = Pure Carbs

The regular Starry formula is carbonated water plus high fructose corn syrup, citric acid, natural flavor, and a short list of preservatives and acidity regulators. High fructose corn syrup is a form of sugar. Sugar counts as carbohydrate. Carbohydrate delivers 4 calories per gram. So if you drink a can with 39 grams of sugar, you’re taking in about 156 calories from sugar alone. The printed panel rounds that down to 150 calories to stay within U.S. labeling rules, and you’ll see that same rounded number on most store shelves.

Why The Label Rounds To 150

Nutrition labels in the U.S. use standard rounding rules from the Food and Drug Administration. That’s why your can lands on a clean “150 calories” instead of 156. You’ll spot similar rounding on sugar. A panel might say “39 g Added Sugars, 78% Daily Value.” That 78% number comes from the Daily Value for added sugar, which sits at 50 grams per day on the Nutrition Facts label. Starry hits most of that Daily Value in one 12-fl-oz can, and a 20-fl-oz bottle blasts past it. This is normal for full-sugar soda in general.

How Starry Fits Into Daily Intake

Calories alone rarely tell the full story with soda. Sugar does. Heart health groups urge people to cap added sugar for the day, not just “watch calories.” The American Heart Association points to a rough upper limit of about 36 grams of added sugar per day for most men and about 25 grams per day for most women, mainly to help manage weight, blood sugar, and long-term heart risk. That means a single 12-fl-oz can of regular Starry can push someone past the daily sugar cap before lunch. A 20-fl-oz bottle blows past that cap for almost anyone. The nutrition panel on Starry lines up with those warnings, because the sugar number is right there in bold. You can also read the same style of limit directly from the American Heart Association sugar limit, which spells out grams per day for men and women.

Starry Sugar Load Versus Daily Added Sugar Cap

Serving	% Of Women’s Daily Added Sugar Cap	% Of Men’s Daily Added Sugar Cap
Starry, 12 fl oz can (39 g sugar)	About 156%	About 108%
Starry, 16.9 fl oz bottle (55 g sugar)	About 220%	About 153%
Starry, 20 fl oz bottle (65 g sugar)	About 260%	About 181%

That table tells the story fast. One can of regular Starry already runs past the daily cap for many women, and it slightly clears the full daily cap for many men. Move from a can to a 20-ounce bottle and you’re looking at two-plus days’ worth of added sugar in one drink by those American Heart Association limits. Starry Zero Sugar flips that script. By dropping sugar to zero, it cuts both the added sugar total and the calorie count to zero, which is why a lot of people reach for the black “Zero Sugar” label when they still want lemon-lime fizz.

Practical Tips To Drink Starry Smart

Pick A Smaller Size

If you like the regular version, grab the 12-fl-oz can instead of the 20-fl-oz bottle. That swap alone trims about 90 calories and roughly 26 grams of added sugar. Another easy play is to pour half a can over ice, top the rest of the glass with plain soda water, and stick the other half can back in the fridge. You still get the lemon-lime pop, just not the full sugar dump all at once.

Pair With Food, Not Mindless Sipping

A sweet drink lands a little softer on you when it replaces dessert, not when it stacks on top of dessert. If you already planned for something sweet at lunch, a small Starry can slide into that same slot. The math is different when the bottle rides shotgun all afternoon while you snack on chips. That habit can drive total calories up fast without any real pause to notice. Swapping in water or unsweetened tea between meals helps space things out and slows the drip of liquid sugar.

Mix Or Swap

Some people rotate regular Starry and Starry Zero Sugar. Others pour half regular Starry and half Zero Sugar in the same cup to cut the sugar in each sip. If you’re tracking grams of added sugar for health reasons, stepping down like that can help you stay under your personal target.
