Whey protein is one of the most widely used protein supplements due to its ability to support both muscle gain and weight management. Most whey protein powders come in either whey protein concentrate or whey protein isolate. 

Whey Protein Concentrate is what’s left after the protein has been extracted from milk and whey protein isolate is what’s left after further processing. Generally speaking, Isolate is the more purer form of whey protein, as much of the carbohydrates and lactose has been removed. For most people Whey Protein Concentrate is more than adequate but for some, especially those keeping a very close eye on calorie content, whey protein isolate is the preferred choice. As Whey Isolate requires further processing it is generally more expensive. 

Whey protein’s three main effects on the body are that it helps Burn Fat whilst Maintaining Muscle, Increase Muscle Strength and Size, and Reduce Hunger. 

Burns Fat while maintaining Muscle
Who doesn’t want to burn fat? Whey protein help enable weight management as it makes the body feel fuller for longer and is slow for the stomach to break down. All the time the protein is powering the muscle to maintain their amino acid profile. 

Increase Muscle Strength and Size
As the muscle cell is made up of fibres that when they get damaged through resistance training, the body adapts and they slowly grown back bigger and with more filaments. Protein is the basic building blocks of this grown so if muscle strength and size is important then protein is absolutely essential. 

Reduce Hunger
Protein is thought to help release the hormone that tells your brain you’re full, therefore consuming protein will assist curbing cravings. This is why many meal replacements contain a substantial amount of protein powder. 

Two other areas often neglected is the use of protein in immunity and as recovery for endurance athletes. As protein contains the building block for cellular recovery, protein can help recover from a weak immune system. Also it is believed that the protein requirements for endurance trainings is actually higher for much heavier body-builders and strength athletes as the damage done to the muscle fibre is just as severe.
