Re: actual summary report ... part 2

Carbohydrates and Sugars:
......... A clue as to why this discrepancy existed was a statement written in small type on the product's label indicating that it contained glycerin but that the manufacturer was not counting glycerin as a carbohydrate (contrary to the FDA's position that glycerin be considered a carbohydrate). Glycerin is commonly used in nutrition bars because it adds a sweet taste and moist texture. .........

Glycerin and polydextrose are also commonly used in sports nutrition bars and energy drinks. Why? Not for the texture and sweet taste. It's because glycerin(e) is rapidly absorbed and used as fuel by the muscles without requiring insulin to do so. It's this property of not causing insulin to rise that is used by the promoters of these products .. to justify their claims that they are acceptable for low-carb diets.
The BIG problem with this is: if your muscles are going to use the glycerin and polydextrose and sugar alcohol as preferred fuel, then what happens to ketosis, and fat-burning as a source of fuel?? It stands to reason that ketone-production and fat-burning will be put on hold while there is glycerin available for fuel. For someone with a fast metabolism, this might not be a problem in the short term, which is likely why they can eat the bars and not get stalled. But for metabolically resistant low-carbers, these products will halt fat-burning and bring on a stall. Regardless whether the carbs are "hidden" or not.
