FAQs
What qualifies as a low‑carb protein powder?
Many brands classify their powders as low‑carb when each serving contains only a few grams of carbohydrate or less. Always check the nutrition panel as flavours may vary.
Isolate vs concentrate: what's the difference?
Whey isolates are filtered to remove more carbs, fats and lactose, leaving a higher protein percentage. Concentrates keep more of the natural milk sugars and fats, so carb content is slightly higher.
Can I use low‑carb protein powder for weight loss?
Protein powders on their own don’t cause weight loss, but many people use low‑carb blends to support a high‑protein diet and help manage appetite. They work best alongside a balanced diet and exercise.
Are low‑carb powders suitable for keto diets?
Many low‑carb powders contain very small amounts of carbohydrate and may fit into a keto eating plan. Check net carbs and adjust your total macros accordingly.
