Grilled corn on the cob calories come to 99 for one medium ear (103 g) and 96 per 100 g, with no butter added. Carbs supply 76% of those calories, so the size of the ear decides the total more than the grill does: a small ear is 85 calories and a large one is 113.

Ear size moves the total more than the grill
The default serving is one medium ear of 103 g, which comes to 99 calories and 5% of the daily value. A small ear of 89 g drops to 85 calories, and a large ear of 118 g climbs to 113. Any single ear stays a light side.
Multiples are where it adds up. Two medium ears total 198 calories, three reach 297, and five, the kind of count that happens at a long summer cookout, hit 494. Five ears still deliver only 17.6 g of protein, so the plate stays carb-heavy at every count.
If you track closely, pick the size class by eye instead of defaulting to large. Better still, weigh one ear once and scale from the 96 calories per 100 g. The gram figure is what every number on this page is built from.
Carbs supply three quarters of the calories
Per 100 g, grilled corn has 21 g of carbs, 3.4 g of protein and 1.5 g of fat. Converted to energy, carbs supply 76% of the calories, while protein and fat each supply 12%. In practice corn behaves like a starchy side, closer to a small serving of grain than to a leafy vegetable.
The sugar is modest for something that tastes this sweet: 4.5 g per 100 g, or 4.7 g in a medium ear. The rest of the carbohydrate is mostly starch, plus 2.4 g of fiber per 100 g. A medium ear gives 2.5 g of fiber and a large ear 2.8 g.
Fat is close to zero on a plain cob. There is 1.5 g of fat and 0.2 g of saturated fat per 100 g, and cholesterol is 0. Anything you brush on before or after grilling sits on top of these numbers.
Sodium comes from the salt, not the corn
The USDA row behind this page is sweet yellow corn cooked with salt, which is why it lists 253 mg of sodium per 100 g. A medium ear carries 261 mg, 11% of the daily value, and a large ear 299 mg, or 13%. For a plain vegetable side, that row stands out.
Compare the boiled corn page, which uses unsalted values: 1 mg of sodium per 100 g with the same 96 calories. Salt does not change the calories, only the sodium line. If you grill your corn without salting it, your real sodium sits much closer to that boiled figure.
Multiples make the salt more visible. Two medium ears reach 521 mg, three reach 782 mg, and five reach 1,303 mg. If you watch sodium, season after grilling with lime, chili or herbs, and make any salt a choice you can see and count.
A light side that needs a protein partner
At 99 calories and 3.5 g of protein, a medium ear covers 7% of the daily protein value. It works best as the starch on the plate, next to grilled chicken, fish, beans or lean burgers, rather than as the main event. That keeps the meal balanced without stacking several starchy sides.
A baked potato with corn on the cob is a classic cookout pairing, but both are starch-heavy. If you want room for both, keep the ear small at 85 calories for 89 g. Corn also brings 218 mg of potassium per 100 g, a useful extra next to salty grilled meats.
Toppings move the number most. Butter, mayo, cheese and oil are not in the figures here, so log them separately. BodyPal can log grilled corn from a photo, which helps when the ear and its toppings land on the same plate.
How does grilled corn on the cob compare?
Here is how grilled corn on the cob stacks up against boiled and canned corn, per 100 g and per usual serving.
Verdict: Grilled and boiled ears are identical at 99 calories per medium ear, so choose the method by taste and watch the salt instead, since boiled is listed at 1 mg of sodium per 100 g against 253 mg here. For the fewest calories per bite canned corn wins at 67 per 100 g, but a 165 g cup lands at 111, more than one medium grilled ear.
