A high-whey protein diet reduces body weight to a greater degree than a diet high in red meat, according to breakthrough research published in the Journal of Nutrition.

Researchers from the University of Adelaide, Australia, fed rats a diet containing either whey protein or red meat for six weeks. Both high-protein diets reduced both visceral fat (the fat that surrounds and protects your organs) and subcutaneous fat (this is the fat under the skin). Whey protein also reduced insulin levels by 40% and increased insulin sensitivity compared to red meat. The researchers conclude a high-protein diet reduces body fat, and that whey protein is more effective than red meat.

So, what’s in the whey that’s responsible for the fat-loss benefits?

You might have seen research linking dairy products with fat loss. At first, researchers thought this was due to calcium. But now they think there is something else in dairy produce that acts (either independently of or synergistically) with calcium to accelerate fat loss.

Dr. Michael Zemel, a fat-loss expert at the University of Tennessee, thinks that this additional activity resides in the whey fraction of milk [2]. “At present, preliminary data suggest that this additional activity resides in the whey fraction of milk,” writes Dr. Zemel in the prestigious Journal of Nutrition. “Whey is recognized as a rich source of bioactive compounds, which may act independently or synergistically with the calcium to attenuate lipogenesis, accelerate lipolysis and/or affect nutrient partitioning between adipose tissue and skeletal muscle.”

Translated, Dr. Zemel means that the bioactive compounds in whey (found in high-quality supplements such as Promax and Cyclone by Maximuscle) limit the storage of body fat, speed up the rate at which you lose fat, and help you build muscle faster!
