Buying Guide
What to consider when choosing a low-calorie whey protein powder
- Protein per serving: Higher protein supports muscle maintenance and satiety. Look for 25–30 g per serving for best results.
- Calorie count: If calories are the primary concern, target powders with 120–150 calories or fewer per serving, depending on your daily plan.
- Carbs and sugar: For low-carb goals, check carbs and sugar; zero-carb or near-zero sugar options are available.
- Ingredients: Single-ingredient or minimally processed options appeal to those avoiding artificial additives.
- Dietary needs: Gluten-free, lactose-free, or dairy-free options may be important for tolerance and gut comfort.
- Flavor vs. unflavored: Flavored powders offer taste, but unflavored can be mixed into foods with fewer calories.
- Digestibility: Look for whey isolate or hydrolyzed forms if digestion is a concern.
