Cranberries (Raw)
4.20g net carbs per 1/2 cup
Served raw and unsweetened, half a cup carries 4.2 g net carbs, so the tart berries work fine for a keto snack or salad topper. Skip the sweetened dried versions and cranberry sauce, since those pile on sugar that raw berries do not.

Good to Know
Buy them fresh in the bag (Ocean Spray sells them seasonally in fall) or grab frozen, which keep year-round and cook down just as well. Watch out for dried cranberries and "craisins," which are almost always soaked in added sugar and can run 25 to 30 g carbs per quarter cup. Toss the raw berries into a salad, simmer them with a keto sweetener for a quick sauce, or scatter a few into sparkling water for color and bite.
Is Cranberries (Raw) Keto? The Full Answer
Cranberries contains 4.20g net carbs per 1/2 cup (6.00g total carbs minus 1.80g fiber). Served raw and unsweetened, half a cup carries 4.2 g net carbs, so the tart berries work fine for a keto snack or salad topper. Skip the sweetened dried versions and cranberry sauce, since those pile on sugar that raw berries do not.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 21% of a 20g daily carb limit. That makes Cranberries a reliable keto staple.
Measure Your Ketone Levels
A blood ketone meter reads beta-hydroxybutyrate from a finger prick, the marker that defines nutritional ketosis at 0.5 to 3.0 mmol/L. Urine strips measure acetoacetate instead, which drops off once you are fat-adapted. Keto-Mojo makes a blood meter.
