Whey is a milk protein that is a popular ingredient in fitness drink mixes. If you use whey protein in concert with a healthy diet and fitness regimen, you will have a better chance of developing lean muscles and lose weight. That’s because whey supports fat burning and gaining lean muscle mass when consumed before exercise.
Where Whey Comes From
Whey protein is a by-product of the process of turning cow’s milk into cheese. There are two types of milk proteins: casein and whey protein. Within the whey category, there are three major forms that are used for weight loss and fitness purposes: whey protein concentrate, whey protein isolate, and whey protein hydrolysate.
Whey’s Fitness Benefits
Whey protein is a plentiful source of branched chain amino acids (leucine, isoleucine and valine). When you are exercising, your body requires higher quantities of branched chain amino acids, otherwise you are more susceptible to fatigue. Whey also contains bioactive ingredients, such as immunoglobulins and lactoferrin, that support proper immune system function.
Studies have found that people who combine a diet with whey protein and exercise have more lean muscle tissue and lose more body fat. This is achieved through various actions. For one, whey protein has been shown to have an effective satiety effect on people. This helps reduce daily calories, and therefore encourages weight loss.
Whey and Healthy Blood Sugar Levels
Whey also appears to be ideal for promoting healthy blood sugar levels through improved insulin sensitivity, which is associated with the reduction of stored fat.
