Always read the label before you buy a dressing or any food for that matter! Avoid vegetable oil, added sugar, and soy-derived ingredients. As long as it’s a whole-foods ingredient list, you’re probably fine because many store-bought salad dressings are naturally keto-friendly. However, note that while macros may be in line with keto, it can be hard to find options with quality ingredients, for that reason, I recommend making dressing at home.
