In the fitness community, Whey is a big deal – But is it backed by scientific facts? What’s just hype and what’s scientifically proven to make a difference? Read to learn about how science backs whey protein supplementation, including actual studies and their results.

Protein Digestibility

There are only two methods worth mentioning about in terms of measuring how well the body takes in Proteins

#1 – The Protein Digestibility Corrected Amino Acid Score. (PDCAAS.) Whey protein tests at a 1.14, which is above 1.0, which is the highest score that the USDA accepts. Whey protein in other words has a reported digestibility of 1.0, when in reality its digestibility score is 1.14.

#2 – The other method is known as Protein Efficiency Score and whey protein scores a staggering 3.2 for this, even way above animal proteins!

Whey Reduces Improper Eating

Whey protein has been proven to reduce Ghrelin, the chemical that triggers hunger and often over eating.

Whey protein will reduce this chemical, reducing in less appetite while simultaneously giving your muscles the protein they need to grow.

An Australian study was conducted where subjects were given one of four drinks. One drink contained Whey, one drink contained Fructose, one contained glucose and one contained whey and fructose. The group was then taken to a buffet a couple hours later.

The study was conducted in a double-blind manner, meaning neither the scientists nor the subjects knew which drink they were taking when they took it. The study revealed that the group who took Whey had less appetite than the other groups for about two to four hours.

Whey is Carb Free and Fat Free

If you’re working out, chances are you’ll want to keep your fat and carb intake pretty low. Unfortunately, most sources of protein are also high in either fat or carbs.

Whey on the other hand, has nearly zero fat and nearly zero carbs. This is a great what to give your muscles building blocks to grow without adding fat or carbs to your body.

This is just a handful of the scientific proof that’s backing Whey protein supplementation. As more and more studies come out and more and more proof stacks up, fitness experts are becoming more and more certain that Whey is the way to go.
