AS far as sugar vs carbohydrates go, Fructose and low GI carbs would most likely be appropriated by the liver glycogen stores, whereas Dextrose and high GI carbs would caus the larger spike in insulin levels thus meaning more fat/muscle gain. Keep in mind though the more liver glycogen stores you have the longer it takes to get back into Ketosis, therefore you would be kicked out longer of ketosis with LOW GI, bit gain more fat with HIGH GI and return to ketosis more easily, so it's kinda a toss up on this issue.


For me I would aim to keep my insulin level under control AT ALL TIME so would avoid the high GI and take the Low, if I had to choose between the two (were talking gunpoint here folks)

This information is in fact the cornerstone for the 'carb-up' period of CKD/BodyOpus plans, Hope this helps.
