Taken from "Carbing Up on the Cyclical Ketogenic Diet" by Lyle McDonald:
"The type of carbohydrate consumed during a carb-up can affect the rate at which glycogen is resynthesized. During the first 24 hours, when enzyme activity is at it's highest, it appears that the consumption of high glycemic index (GI) foods such as simple sugars promote higher levels of glycogen resynthesis compared to lower GI foods like starches (5,7,8). Glycogen resynthesis during the second 24 hours has not been studied as extensively. It appears that the consumption of lower GI carbs (starches, vegetables) promotes higher overall levels of glycogen resynthesis while avoiding fat gain by keeping insulin levels more stable (9). Most individuals find that their regain of bodyfat, as well as retention of water under the skin, is considerably less if they switch to lower GI carbohydrates during the second 24 hours of carbohydrate loading. Fructose (fruit sugar, which preferentially refills liver glycogen) will not cause the same amount of glycogen resynthesis seen with glucose or sucrose (5, 8). Whether liquids or solid carbohydrates are consumed also appears to have less impact on glycogen resynthesis as long as adequate amounts are consumed (10). Anecdotally, many individuals have had success consuming liquid carbohydrates such as commercially available glucose polymers during their first few meals and then moving towards slightly more complex carbohydrates such as starches. Liquid carbohydrates should raise insulin even more than solid carbs, which is useful during the initial hours of the carb-load."
