Why Protein Matters on a Keto Diet
The ketogenic (keto) diet is a low-carb, high-fat way of eating designed to put your body into ketosis, a metabolic state where fat is burned for fuel instead of carbohydrates. According to Harvard T.H. Chan School of Public Health, the keto diet can help with weight loss, improve metabolic health, and support brain function. For a more in-depth breakdown of how ketosis works, check out this comprehensive guide on ketosis.
One of the key macronutrients in a keto diet is protein, which helps maintain muscle mass, supports metabolic function, and keeps you feeling full longer. However, consuming too much protein can lead to gluconeogenesis, where excess protein is converted into glucose, potentially affecting ketosis.

While whole-food protein sources like meat, fish, and eggs are ideal, a high-quality keto-friendly protein powder can be a great addition to your diet—especially for those with an active lifestyle or busy schedule. The challenge? Many protein powders contain hidden sugars, artificial additives, or high-carb fillers that can kick you out of ketosis. That’s why we’ve curated a list of the five best keto-friendly protein powders that meet strict clean ingredient standards and provide optimal nutrition.
