Can you eat Greek yogurt on keto? The short answer
For those on a ketogenic diet, plain, full-fat Greek yogurt is a viable option when consumed in moderation. The key is selecting the right product and carefully monitoring portion sizes to ensure it aligns with your daily carbohydrate limits, which are typically between 20 and 50 grams for standard keto diets. The straining process that gives Greek yogurt its thick texture also removes some of the carbohydrate-containing whey, resulting in a lower sugar content than its regular yogurt counterparts. This makes it a superior choice for keto dieters compared to standard or flavored yogurts, which are often packed with added sugars.
The nutritional benefits of plain Greek yogurt
Beyond its lower carb count, plain Greek yogurt offers several nutritional advantages that can be beneficial on a keto diet:
- High in protein: Greek yogurt packs a significant amount of protein, which helps increase satiety and reduce overall calorie intake. This can be particularly helpful for managing appetite and supporting muscle mass, especially for those who are physically active.
- Rich in healthy fats: Choosing a full-fat version provides a good source of dietary fat, which is the primary energy source on a ketogenic diet. This helps support the body's shift into and maintenance of ketosis.
- Source of essential nutrients: Greek yogurt contains important micronutrients like calcium for bone health and vitamin B12 for energy production. This helps address potential nutrient deficiencies that can occur on a restrictive diet.
- Contains probiotics: As a fermented food with live and active cultures, Greek yogurt introduces beneficial bacteria to the gut, which is important for digestive health.
How to choose the right Greek yogurt for keto
Not all Greek yogurts are created equal when it comes to the ketogenic diet. Here’s what to look for and what to avoid:
What to look for:
- Plain, full-fat: Always opt for plain, unsweetened varieties made with whole milk. This ensures the highest fat content and lowest carb count. Check the label to verify it is free from added sugars and artificial sweeteners.
- Check the carb count: Even among plain versions, carb counts can vary by brand. Look for products with around 5–7 grams of carbs per serving to stay safely within your daily allowance.
- Live and active cultures seal: A "Live & Active Cultures" (LAC) seal indicates the presence of beneficial probiotics, supporting gut health.
What to avoid:
- Flavored and fruit-on-the-bottom: These contain significant amounts of added sugar, which will quickly derail your ketosis. The high carb content makes them unsuitable for keto.
- Low-fat and fat-free: Manufacturers often replace the fat with carbohydrates and thickeners, which increases the sugar content. These products are typically higher in net carbs and should be avoided.
Portion control and managing protein intake
Even with the right type of Greek yogurt, moderation is key. A single 5–7 ounce serving of plain Greek yogurt typically contains 5–9 grams of carbohydrates, which can be a significant portion of a 20–50 gram daily carb limit.
Additionally, managing your protein intake is important on a ketogenic diet. While protein is necessary, consuming an excessive amount can lead to gluconeogenesis, a process where the body converts protein into glucose, which can inhibit ketosis. A moderate protein intake of 15–20% of your daily calories is generally recommended for keto. A single serving of Greek yogurt fits well within this range, but relying on it as a primary protein source throughout the day could lead to overconsumption.

Keto-friendly Greek yogurt meal ideas
- Keto yogurt bowl: Mix plain, full-fat Greek yogurt with a handful of low-carb berries (like raspberries or blackberries) and sprinkle with nuts or seeds for added healthy fats.
