Not an expert but I believe this does not work. Sugar bound up in fiber (as is the case with natural fruit) is not immediately bioavailable. Your GI tract needs to break down the fiber in order to release the sugar, which takes time. The sugar is absorbed by your small intestine more slowly, causing a gentler glycemic response. This is analogous to 'extended release' medication, where the dose is delivered slowly over a longer period of time. Separating the sugar from the fiber (as with juicing) means that all the sugar is bioavailable more or less immediately after you consume it, Causing the blood sugar high followed by the insulin spike. Adding fiber to your sugary meal does little to slow this down.
