Check out our original overview of whey protein benefits. In this post we’re going to delve a little more into how whey protein effects the growth of lean muscle mass, as well as fat burning and weight loss, specifically with the use of whey protein powder.

How Whey Protein Powder Increases Fat Loss and Lean Muscle Mass:
In a recent study from the Minnesota Applied Research Centre, they evaluated how a high quality whey protein source used as a daily dietary supplement enhanced the rate of fat burning and subsequently weight loss by comparing subjects consuming whey protein on a daily basis with a control group, both on a reduced caloric intake diet. They found the following:
- Over 12 weeks, the whey protein powder using group lost a substantial amount of fat compared to the control group, specifically 1.2 kg of fat. While not sounding like a significant amount of weight, the supporting tissue and blood supply adds much more.
- On top of that, while the entire control group lost lean muscle mass over the course of the study, some members of the whey protein actually gained lean muscle mass over the 12 weeks, and the average loss of lean muscle mass was far less (1.35 kg less to be exact)
- This is all while changing nothing else about there lifestyle, and the results of this study were found to have major significance in using whey protein as a supplement for fat burning and weight loss.
- Whey protein powder benefits all lean muscle groups, but was shown to especially benefit fast-twitch muscles that provide bursts of power for weight lifters, sprinters, etc.
- Hyperinsulinemia (hormone that stores fat, and is found in short supply within hours of consuming whey proteion)
- Cortisol (promotes lean muscle growth and conservation when going on a “cut” for those fitness buffs out there)
- Increased Ghelin (reduces hunger, and makes you feel full)
