When in doubt, ask Justin Harris.

Question:
Rob Kreider said at the Arnold strength seminar that we shouldn't use waxy maize cause it dosn't create an insulin surge? is this true?
Answer:
I've written extensively on this. Those commenting on waxy maize's effects on insulin production are, for the most part, speaking on an urelated subject.
Insulin is secreted in response to blood sugar. 100g of carbs will produce a resultant insulin production. Waxy maize won't produce the level of insulin surge for reasons that make it BETTER.
The HIGH molecular weight and LOW osmolality of the waxy maize causes a rapid gastric clearance rate. This low osmolality dictates that monosacharides are taken to the blood streams very rapidly. HMW carbs replentish glycogen faster than LMW carbs.
Sugar causes a huge insulin spike...this is good....when it FINALLY happens after 20min of drawing water into your stomach. By the time if finally gets to the small intestine, waxy maize has already been taken up to the muscle and is stored as glycogen.
Imagine a race with a formula 1 car and a Bentley. Now, imagine that the formula 1 car has to be put together before it can start the race. Of course it is faster than the bentley when it finally gets going, but by then, the bentley has already finished the race.
Insulin is very misunderstood by many people.
What makes waxy maize good is its molecular weight. Measuring molecular weight isn't a unique or rare phenomenon. Molecular weight is covered in high school chemistry, and every chemistry class after that.
The molecular weight of water would go as this:
Water is 2 hydrogen atoms and 1 oxygen atom.
The atomic weight of hydrogen is approximately 1.
The atomic weight of oxygen is approximately 16.
Take 2 hydrogen and 1 oxygen, and you get a combined atomic weight for a single water molecule of 18.
The molecular weight stems form the statement that one mole of water will have a mass of roughly 18 grams. (weight is used interchangeably here...although weight is only really a component of earth's gravity creating an acceleration of 9.8m/s. Since we don't typically measure molecular mass on other planets, weight and mass are used as the same with this)
Look up hypotonicity online and you'll see why this is all important.
A HMW carb in a 15% solution is as much as 20 TIMES as hypotonic as blood.
Glucose based exercise drinks are often promoted as "isotonic" solutions. This is marketing to an uneducated consumer at its finest. The isotonicity of the drinks makes it a POOR choice for its intended use.
There is actually a book called "Performance Functional Foods" that covers this topic in some depth.

Oh well, I guess I'll see how it works for me and use that as the basis for my next order. I've been using WMS but not crazy about the little clumps that never seem to break up. Thanks fatty, and I used your discount code for true protein and so did my boss.:icon_chee
