Is Greek yogurt 2g low fat Keto?

The Ingredient Breakdown

As a food scientist, I look beyond the marketing claims and dive straight into the formulation. The base of this product is cultured pasteurized nonfat milk and milk protein concentrate. This is standard for creating a thick, high-protein yogurt without the natural fat content of whole milk. While dairy proteins are generally acceptable on a Keto diet, the rest of the ingredient list tells a different story.

The primary red flag for a Keto dieter is the presence of cane sugar. Even small amounts of added sugar contribute directly to your daily net carb count. In a strict Keto regimen (usually 20-50g net carbs per day), every gram counts, and added sugar is the most efficient way to exceed that limit.

To compensate for the removal of fat and the need for sweetness, the manufacturer uses a blend of stevia and sucralose. While these are zero-calorie sweeteners, they can still trigger an insulin response in some individuals (a phenomenon known as the cephalic phase insulin response). Furthermore, the inclusion of fruit and vegetable juice concentrate is used for color, but it often contains trace sugars that add to the total carbohydrate load.

Nutritional Value

From a nutritional standpoint, this product is a paradox. It is low in fat (2g), which contradicts the high-fat requirement of the Keto diet. Keto relies on fat as the primary energy source; this yogurt relies on protein and carbohydrates.

The specific carbohydrate count is where the product fails the Keto test. The presence of cane sugar ensures that the 'Total Sugars' line item is non-zero. For a food to be truly Keto-friendly, it should ideally have zero added sugars and a very low total carbohydrate count. While the net carbs might appear low on paper, the combination of sugar and artificial sweeteners makes it a risky choice that could stall weight loss or kick you out of ketosis.
