Grapes fit a weight-loss plan when you serve a cup instead of eating from the bunch. A cup of green seedless grapes (100 g) gives 54 kcal and 11.8 g of carbohydrate with 1.3 g of fibre. Variety matters more than people think: IFCT shows black oval grapes carrying much more.

The verdict on grapes

Whole fruit

One counted fruit in place of a sweet or a packet snack.

  • 1.1 g of protein for every 100 kcal.
  • One serving gives 0.6 g of the roughly 58 g of protein a day ICMR-NIN's RDA sets for a 70 kg adult.
  • 1.3 g of fibre in a serving.

How grapes fits a plan that loses fat and keeps muscle

Green seedless grapes are mostly water, at 54 kcal per 100 g in IFCT 2017. They are low in fibre for a fruit, so they are easy to keep eating. Put a measured cup in a bowl and the snack stays a snack.

The table below shows why the variety matters: IFCT's black oval seedless grapes run far higher per 100 g than the green round ones. If your local grapes are the dark, oval kind, use a smaller cup.

Grapes in an Indian kitchen

Wash grapes well under running water; they are among the fruits most likely to carry pesticide residue. Count them out into a bowl rather than eating from the bunch, since a cup goes quickly. Frozen grapes are a cold, slow snack in summer. Black, green and red grapes are close in calories. Raisins are grapes with the water removed, so a small handful of kishmish carries the sugar of a much larger bowl of fresh grapes.

Pair it, or swap it

Grapes with a few walnuts or a cube of paneer slow the sugar down. Frozen grapes make a sweet after-dinner bite that takes a while to eat.

Worth knowing

Raisins are dried grapes, more than five times as calorie-dense by weight in IFCT 2017. Grape juice removes the fibre altogether.

Grapes: questions people ask

How many calories are in grapes?

Green seedless grapes are 54 kcal per 100 g in IFCT 2017. Black oval seedless grapes are much higher; see the table.

Are grapes good for weight loss?

Yes, in a measured cup. They are watery and low in calories, but low in fibre, so serve them in a bowl rather than eating from the bunch.

Black or green grapes for weight loss?

In IFCT 2017, green seedless grapes are lower in calories than black oval seedless grapes per 100 g. Both fit in a measured portion.
