Unsweetened Greek yogurt is a thick, protein-rich yogurt that has been strained to remove much of the whey. It contains some natural milk sugar (lactose), but is generally low to moderate in carbs depending on fat level and brand. It can fit low-carb and diabetic-friendly eating when portioned, but it is not always ideal for strict keto in larger servings.
