keto-friendly protein bars are snacks designed for those following a ketogenic diet, which emphasizes low carbohydrate intake and high fat consumption. These bars typically contain high-quality protein sources, such as whey or plant-based proteins, while minimizing sugars and carbs. Many keto-friendly protein bars use alternative sweeteners like stevia or erythritol to maintain flavor without adding significant carbohydrates. They often include healthy fats from ingredients like nuts, seeds, or coconut oil, making them a convenient option for on-the-go snacking while supporting a low-carb lifestyle.
