Whey, Casein, or Whole Food

Whey protein digests quickly, peaks blood amino acids fast, and is well suited to the period right after training when convenience matters and appetite may be low. Casein digests slowly, releasing amino acids over many hours, which makes it useful before a long gap between meals, most often before sleep.

Whole-food protein is what should make up the bulk of your intake. It comes packaged with micronutrients, fiber, and chewing, all of which contribute to satiety and overall nutrition in ways powder cannot. Eggs, fish, lean meats, dairy, and well-prepared legumes form the foundation of any serious diet.

Supplements are a tool, not a tier. Use a scoop of whey when whole food is impractical. Use casein if your evening schedule leaves a long fast before bed. Otherwise, eat your protein. Powder fills the gaps. Food fills the day.
