Plum
6.60g net carbs per 1 fruit
Budget carefully, since one fruit runs 6.6 g net carbs, which can eat up a big chunk of a strict 20 g daily limit. Slice half into a bowl of full-fat Greek yogurt if you want the taste without spending your whole carb allowance at once.

Good to Know
A ripe plum gives slightly under the firm one, so picking fruit that yields just a little to gentle pressure means you taste more sweetness from the same 6.6 g net carbs. Dried plums (prunes) are a different story entirely, since drying concentrates the sugar and a few pieces can carry several times the carbs of one fresh fruit. Pair half a plum with something fatty like a slice of brie or a handful of almonds to slow things down and stretch out a small serving.
Is Plum Keto? The Full Answer
Plum contains 6.60g net carbs per 1 fruit (7.50g total carbs minus 0.90g fiber). Budget carefully, since one fruit runs 6.6 g net carbs, which can eat up a big chunk of a strict 20 g daily limit. Slice half into a bowl of full-fat Greek yogurt if you want the taste without spending your whole carb allowance at once.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 33% of a 20g daily carb limit. Track your portions carefully and account for other carbs in your meals.
Better Keto Swaps
Blackberries are your best stand-in here. Half a cup runs about 3.1 g net carbs, and they bring that sweet-tart bite without spiking you. Want something even leaner? Try raspberries, which land near 3.3 g net carbs per half cup and pack solid fiber. For a bigger volume snack, sliced strawberries work well too, sitting around 4 g net carbs per half cup so you can eat a real handful and still stay in range.
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.
