Not Keto
Oat Milk
14.00g net carbs per 1 cup
Creamy and lightly sweet, one cup carries 14 g net carbs, which can use up most of a strict keto day in a single pour. Reach for unsweetened almond or coconut milk instead, since they run far lower per cup.

Good to Know
Even brands labeled unsweetened, like Oatly Barista or Chobani, still carry that oat-based carb load because the milk is made by breaking down whole oats into sugars. If you want a splash in coffee, unsweetened almond milk (around 1 g net carb per cup) or coconut milk are far friendlier swaps. Watch the flavored cartons too, since vanilla and chocolate oat milks can push past 20 g per cup with added sugar.
Is Oat Milk Keto? The Full Answer
Oat Milk contains 14.00g net carbs per 1 cup (16.00g total carbs minus 2.00g fiber). Creamy and lightly sweet, one cup carries 14 g net carbs, which can use up most of a strict keto day in a single pour. Reach for unsweetened almond or coconut milk instead, since they run far lower per cup.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 70% of a 20g daily carb limit. If you are following a strict ketogenic protocol, reach for a lower-carb option instead.
Better Keto Swaps
Unsweetened almond milk is the easy stand-in here, pouring just about 1 g net carbs per cup while keeping that pourable, neutral texture for coffee or cereal. Coconut milk from a carton (the unsweetened drinking kind, not canned) runs around 1 to 2 g net carbs per cup and adds a little richness if you want body in a smoothie. Macadamia milk is another solid pick at roughly 1 g net carbs per cup, with a slightly creamier mouthfeel that works well in tea. Each one swaps out the 14 g net carbs you'd get from a cup of the oat version while staying well within a keto budget.
