Purple grapes calories come to 104 for one cup (151 g) and 69 per 100 g. Almost all of that energy is sugar: a cup carries 23.4 g of sugars, while protein and fat barely register. The portion is the whole story, because grapes are very easy to keep eating.

A cup is 104 calories, a big bowl is 521
Ten purple grapes weigh about 49 g and come to 34 calories. A standard cup holds 151 g and lands at 104, which is 5% of a 2000-calorie daily value. The generic serving of 126 g sits between them at 87 calories. On paper, any of these is a light snack.
The catch is how grapes get eaten. They come off the stem one at a time, there is no peel or pit to slow you down, and a bunch on the counter rarely stops at a single cup. Two cups (302 g) bring you to 208 calories. Three cups, roughly 453 g, reach 313. Five cups, the kind of bowl that disappears during a movie, add up to 521 calories.
If you track, weigh the bunch once or count a portion into a bowl instead of eating from the bag. Ten grapes is a handy mental unit: each handful of that size is about 34 calories, so the math stays simple even when you go back for more.
Nearly every calorie is carbohydrate
Carbs supply 94% of the calories in purple grapes. Protein adds 4% and fat 2%. Per 100 g, that means 18.1 g of carbohydrate against 0.7 g of protein and 0.2 g of fat, with saturated fat at 0.1 g.
Most of that carbohydrate is sugar: 15.5 g per 100 g, or 23.4 g in a cup. Fiber is modest at 0.9 g per 100 g, so a cup gives 1.4 g, a small slice of the 28 g daily value. That mix is why grapes taste sweet and go down fast, without much bulk to make you pause.
Protein is close to absent. A cup has 1.1 g, which is 2% of the 50 g daily value, and even five cups only reach 5.4 g. Cholesterol is 0 and sodium is 2 mg per 100 g, so the only rows that really move are calories and sugar. Grapes are fruit, not a meal, and the numbers say so plainly.
Sodium is near zero, potassium carries the mineral row
Purple grapes have 2 mg of sodium per 100 g. A cup has 3 mg, and its share of the daily value rounds to 0%. Even five cups total only 15 mg against a 2300 mg daily value. If you watch sodium, grapes are one of the easiest snacks to fit into a day.
Potassium is the more interesting mineral line at 191 mg per 100 g. That is a small share of the 4700 mg daily value, but it arrives with almost no sodium attached, which you cannot say about salty packaged snacks.
Fat, saturated fat and cholesterol are all trivial here: 0.2 g, 0.1 g and 0 per 100 g. The label for grapes is short and clean. Nothing on it needs a second look except the portion itself, since calories and sugar are the only lines that grow meaningfully as the bowl gets bigger.
Pair grapes with protein to make the snack last
A cup of purple grapes brings 104 calories, mostly as sugar, and only 1.1 g of protein, so it works best next to something that fills the gaps. Cheese, a handful of nuts, Greek yogurt or a few slices of turkey add the protein and fat that grapes lack. The plate then feels like a snack rather than a quick sugar hit.
Grapes also work as a dessert stand-in. Frozen grapes eat slowly, which helps if a bowl tends to vanish. In salads, a handful adds sweetness without a heavy calorie load; toss them with greens, chicken and a sharp dressing for contrast.
If you log food, BodyPal can log a bowl of grapes from a photo, but weighing once is still the best way to learn what your usual handful looks like. After that, ten grapes at 34 calories or a cup at 104 are easy reference points you can carry in your head.
How does purple grapes compare?
Here is how purple grapes stack up against black, green and red grapes, per 100 g and per usual one-cup serving.
Verdict: The numbers are identical: all four come to 104 calories per cup and 69 per 100 g, with the same 18.1 g of carbs. Pick the color you enjoy most, because for weight loss the portion matters and the variety does not.
