How Protein Helps Promote Weight Loss

Bodybuilders often take a powdered form of protein, the essential building blocks for muscle. Protein powder is generally consumed immediately after exercising, or in place of a meal. Having sufficient protein intake allows for efficient growth and repair of muscle tissue.

• Whey protein is the most commonly used type of protein. It contains high levels of all the essential amino acids not produced by the human body, and is absorbed by the body very quickly.
• Casein protein is the richest in glutamine, an amino acid that aids in recovery, and has casomorphin which helps the body to absorb the amino acids over a long time.
• Soy protein contains all essential amino acids, and is an alternative protein for vegetarians. However, soybeans contain a type of phytoestrogen called isoflavones which have a weak estrogenic activity.
• Egg white protein is a lactose- and dairy-free protein.

Whey protein is the name for a collection of globular proteins that can be isolated from whey, a by-product of cheese manufactured from cow's milk. It is typically a mixture of beta-lactoglobulin (~65%), alpha-lactalbumin (~25%), and serum albumin (~8%), which are soluble in their native forms, independent of pH. Whey has the highest Biological Value (BV) of any known protein.

Whey is a lactose-free or reduced lactose protein loaded with nutrients and essential amino acids. Whey comprises four major protein fractions and six minor protein fractions. The major protein fractions in whey are beta-lactoglobulin, alpha-lactalbumin, bovine serum albumin and immunoglobulins. Each of these components have important disease-fighting effects. In addition, whey protein is easily digestible.
