I stumbled across Mike Arnold talking a out HBCD. This is some good shit!:
"The foundation of thisprogram rests on the specific type of macros used. Without them, every single other component/aspectof this program is negatively affected and in some cases rendered ineffectivealtogether. High molecular weightcarbohydrates, such as branched chain cyclic dextrins, have been shown to besuperior to any other form of carbohydrate in multiple ways, such as: 1) A much faster rate of digestion andassimilation. 2) Improved glycogen compensation. 3) Enhanced insulin release. 4) The ability to pull other nutrients intocirculation at a more rapid rate (vacuum effect). 5) The inability to cause intestinal waterretention, unlike other forms of carbohydrates, such as dextrose &maltodextrin. The result is zerobloating, no indigestion, and a tighter midsection. 6) The ability to initiate an osmotic affectat the cellular level, in which the balance of water is shifted in favor of themuscle cell & bloodstream and away from the subcutaneous region (the resultis a fuller, drier physique). 7) Less likely to add bodyfat. Using other forms of carbohydrates will bringinferior results and therefore, it is not advised that the individual usesubstitutions for this part of the program."
