Why You Should Be Consuming Whey Protein Isolate

Why should everyone consume Whey Protein Isolate? To paraphrase John Kiefer, a nutrition and exercise expert who uses his background in physics to squeeze the most out of the human body, in terms of muscle growth, fat loss, and performance:

Everyone who trains knows that whey increases muscle growth better than most proteins especially when taken post-workout. And its derivatives—like whey hydrolysates—outperform almost all other proteins when it comes to potentiating and supporting growth.


Besides hypertrophy, whey isolate has advantages that are ignored or unknown by nutrition experts.Whey isolate is particularly effective at alleviating and preventing oxidative damage.It works by increasing levels of an amino acid called glutathione, which fuels the main anti-oxidant machinery of the cells in the body.Glutathione also helps recycle other antioxidants like vitamin C and vitamin E, decreasing the need for these vitamins.


As you'll see, the two systems differ wildly.The benefits of eating fruits and vegetables pales in comparison to the glutathione.Anti-oxidants of the fruit-and-veggie type float around the blood stream and might bump into a free radical, neutralize it, and prevent it from doing damage.Even with massive amounts of blood-born anti-oxidants, it's still a crap-shoot as to whether free radicals get nullified.In contrast, the glutathione-driven system, works within each cell, so cells neutralize the free-radical, thus preventing an attack. 


The analogy I use involves burglars. The fruit-and-veggie antioxidants represent the police and glutathione, three trained Rottweilers. The police might stop a burglar from breaking-and-entering if they drive by at the exact moment the burglars burgle, or if they accidentally crash into the burglar's car en route.The Rottweilers, however, will stop the burglars every time.Even if one guard dog goes down, the others continue preventing damage.Whey isolate feeds the pack of attack dogs in each cell.

For myself, whey isolate has helped me to create peri-meal supplementation for enhanced goals.Peri-meal supplementation or supplementing around eating means ingesting certain foods at certain times around a meal.The supplementation changes when and to what extent the body releases hormones.

Consuming 10 grams of whey isolate a few minutes before a meal, for example, decreases the amount of insulin released and can assuage hunger.(Reference “The Importance of Understanding Insulin” to understand why regulating insulin is important).

What are you to do?

Consume whey protein not just as a pre-and-post workout shake but 10 grams before meals.Consuming the whey will decrease your insulin and help manage your hunger.
