What Is Whey Protein and Why Do People Use It?
Whey protein is a complete protein, meaning it has all nine essential amino acids your body needs. It comes from the liquid part of milk that separates during cheese making. There are three main types: concentrate, isolate, and hydrolysate.
-
Whey Protein Concentrate: This has 70-80% protein, with some lactose and fat. It's tasty but higher in calories.
-
Whey Protein Isolate: This is more processed to remove most lactose and fat, giving 90% or more protein. It's lower in calories and easier to digest.
- Whey Protein Hydrolysate: This is pre-digested for even faster absorption, but it's usually the most expensive.
People use whey protein for many reasons:
- To build muscle after workouts.
- To help with weight loss by keeping you full.
- To recover faster from exercise.
- To add protein to meals when you're busy.
The calories in 1 scoop of whey protein depend on the type and brand. A basic scoop of isolate might have 100-120 calories, while concentrate can be 120-140 calories. Some flavored or added-ingredient versions go higher.
