For weight loss, the best protein is one you can eat often: lean whole foods or simple whey, in a daily amount that keeps you full on fewer calories.

The best protein to use to lose weight is any filling, high-quality source you can eat consistently, such as whey, casein, soy, eggs, fish, or lean meats.

For healthy weight gain, the best protein sources combine high calories, quality amino acids, and easy digestibility suited to your daily routine.

For most lifters, whey and other leucine-rich proteins give the best lean muscle gains when daily protein and training are consistent.

For best protein type for muscle gain, whey isolate or a whey–casein blend gives fast and steady amino acids that help strength and size gains.

For muscle growth, fast-digesting whey or a well-planned protein blend paired with enough daily protein gives the most reliable results.

Different protein types from plants and animals help you build muscle, manage weight, and protect health when you mix them through the week.
