How many carbs are in a peach?
A medium peach (150g) has about 14g of carbohydrate and 12g of net carbs. Peaches are a lower-carb summer fruit, well below tropical fruits like mango or pineapple.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 medium peach (150g) | 14.3g | 2.2g | 12.1g |
| 1 small (130g) | 12.4g | 1.9g | 10.5g |
| 1 large (175g) | 16.7g | 2.6g | 14.1g |
| 100 grams | 9.5g | 1.5g | 8.0g |
Net carbs
A medium peach has about 12g of net carbs, which is total carbs (14.3g) minus fiber (2.2g). The fiber content is modest but meaningful. See the net carbs guide.
Glycemic index of a peach
The glycemic index of a peach is about 42. Peaches have a low glycemic index. Most of their sugar is a mixture of sucrose, glucose, and fructose, and the soluble fiber in the flesh slows digestion. A very ripe, soft peach has slightly more free sugar and a marginally higher GI than a firmer, less ripe one.
For diabetes
A medium peach delivers about 14g of total carbs with a low GI of 42, which makes it one of the more diabetes-friendly fruit choices. The glucose rise is gradual compared with high-GI fruits. Peach juice and canned peaches in syrup are different, delivering more carbs faster with less fiber. Fresh peach is the most predictable form. Count total carbs as part of your meal and match to your dose ratio. See the diabetes carb-counting guide.
Keto and low carb
A medium peach has about 12g of net carbs. That is a manageable amount within a 20g keto budget if you have room and the rest of your day is low-carb. A small peach (130g) has about 10g of net carbs. Peaches are one of the more keto-compatible tree fruits because of their relatively low sugar density.
Good to know
White peaches have slightly less acidity than yellow peaches and taste sweeter even when the sugar content is similar. The fuzzy skin is edible and contributes a small amount of fiber. Nectarines are genetically similar to peaches, smooth-skinned, and have a nearly identical carb profile. Canned peaches in heavy syrup can reach 20g of carbs per half cup, almost double a fresh peach at the same serving size, because of the added sugar in the syrup.

Are peaches good for diabetics?
Yes, fresh peaches are a reasonable fruit choice. The low GI and 14g of carbs per medium fruit make them easier to fit into a meal plan than tropical fruits. Avoid canned peaches in syrup, which can double the carb count.
Are nectarines the same as peaches in carbs?
Yes, nearly identical. Nectarines are a smooth-skinned genetic variation of the peach and have the same carb, fiber, and sugar profile per gram.
