Low-glycemic vs. High-glycemic...I'm glad you asked

Stephanie brings up my next valid point.

What is the connection of low-glycemic carbs and high glycemic carbs to a healthy and productive diet?

The Glycemic Index is a measure of a carbohydrates rate of breakdown and affect on blood-sugar levels and insulin response.

When you consume a carb it immediately goes into absorption. When this happens, depending on the speed of absorption, your body responds by creating insulin in an effort to facilitate storage of glucose in muscles and liver.

Now, high-glycemic foods absorb rapidly and this leads to a few variables.
1. Rapid absorption creates a surge of blood-sugar (glucose) thereby creating an insulin surge response. When this happens, insulin brings fat burn to an outright halt thereby causing preferential absorption. Think of drinking a soda. You end up burning nothing but sugar.
2. Rapid absorption also leads to being hungry sooner. This is the reason you feel full longer when you eat lots of meat. Protein takes longer to absorb than anything else so you don't have those hunger pangs.
3. Rapid glucose surges will possibly lead to insulin resistance whereby the body's normal insulin response is not enough to carry out normal metabolic functions thereby leading eventually to elevated blood glucose levels which could lead to Type 2 Diabetes. That is no good.
