Keto
The ketogenic (keto) diet restricts carbohydrates to roughly 20 to 50 grams per day to push the body into ketosis, a metabolic state where fat-derived ketones become the primary fuel source instead of glucose. Protein intake is moderate, with most calories coming from fat.
Why It Matters
Keto-compatible protein powders need to be ultra-low in carbs, which usually means whey isolate or hydrolysate (1 to 3g carbs per serving). Mass gainers, milk-based RTDs, and most plant blends are too high in carbs to fit comfortably.
Keto lifters often struggle with leucine timing because of low total food volume. A keto-friendly whey isolate post-training is the most efficient way to hit the leucine threshold without breaking the carb cap.
How to Spot It on a Label
Look for keto-friendly or zero net carb badges on the front. Verify by checking Net Carbs in the Nutrition Facts: under 3g per serving is comfortably keto, 4 to 6g is borderline, anything higher needs to be counted carefully.
