Is Greek yogurt keto-friendly?

Plain full-fat Greek yogurt is low enough in net carbs for keto in normal servings. Flavored and low-fat cups usually add enough sugar to push them out.

Why this answer

• Straining removes much of the whey and lactose that regular yogurt carries, which is why plain Greek yogurt is lower in net carbs than regular yogurt at the same serving size.
• The remaining carbohydrate in plain Greek yogurt is lactose, a milk sugar, not fiber, so there is no meaningful gap between total and net carbs.
• Full-fat versions are generally preferred on keto because low-fat and non-fat Greek yogurts often replace the removed fat with added starch or sugar to preserve texture.
• Flavored cups list sugar as a top-three ingredient by weight in most cases, which is what drives the net-carb count up rather than the yogurt itself.
• Live active cultures do not change the carbohydrate count; they affect digestion, not the nutrition label.

What to look for on the label

• Cultured milk
• Live active cultures
• Cream in full-fat versions
• Added sugar or fruit purée in flavored cups

Lower-carb swaps

• Plain full-fat Greek yogurt with a few berries added at home
• Plain full-fat Icelandic-style skyr, which has a similar strained profile
• Unsweetened coconut yogurt for a dairy-free, lower-carb option

How this answer was reached

Every entry in this library starts from a food's total carbohydrate and fiber content, because net carbs — total carbs minus fiber — is the number most keto plans actually track, not total carbohydrate alone. Where added sugar, starch or fillers change the count between brands or preparations, we say so instead of forcing a single verdict.

Standard keto plans target roughly 20 to 50 grams of net carbs per day, though the exact number varies by person and by how strict the plan is. A food that looks healthy in general nutrition terms is not automatically keto-compatible — quinoa and bananas are two common examples where the two questions have different answers.
