Stay AWAY from WHEY according to study:
Even folks who have never worked out have heard of whey protein supplement. Some of the worst, cheapest whey protein can easily be purchased at your local Wal-Mart. My former military boss used to say: “If Wal-Mart ain’t got it, I don’t need it”.
FACT: Even the so-called highest quality WHEY protein (heavily advertised in the body building rags) that you practically have to take a loan to purchase from your trusted “GNC- Heath Food Center- or local Vitamin Shoppe could very likely be causing FAT GAIN as opposed to fat loss.
If after all you think you must consume WHEY protein DO NOT CONSUME during these times:
1. During the day
2. In the evening
WTH! No that isn’t a misprint – you read it clearly. Whey protein simply isn’t a great protein to consume at any time of day, and for specific reasons.
1. Whey Protein Absorption – A review on the rate of protein absorption published in 2006 in the International Journal of Sport Nutrition and Exercise Metabolism reported that whey protein isolate absorbs at a rate of about 8g/hour. This is in large part due to the fact that whey is not broken down into small enough peptides by our body’s natural enzymes in time to be absorbed.
Combined with the fact the window of opportunity for whey protein to be absorbed is 1.5 hours, your body at maximum will be able to absorb 12 grams of whey protein from a single serving.
Kind of makes those 40g whey protein shakes seem foolish, doesn’t it? Well, that’s because they are.
Simply put, whey protein passes through the system far too rapidly to be adequately absorbed, leaving the majority of your protein shake wasted…literally.
2. Insulin Release Associated With Whey – Which of the two items below cause a greater spike in insulin?
a) White Bread
b) Whey Protein
Well, as you can probably guess, if you chose the horrendous, high glycemic, void-of-all-nutrition white bread, you’d be 100%…WRONG.
BAZINGA, a 2012 study published in Nutrition & Metabolism identified that the specific amino acids in whey protein stimulate beta cells to secrete more insulin than a similar amount of carbohydrate from white bread.
In the presence of insulin, fat burning essentially stops.
This makes a whey-protein-only supplement a big-time no-no for evening use, especially pre-bedtime when avoiding spikes in insulin are paramount as metabolism is already slowing down in preparation for its normal, much slower sleep rhythm.
