Wielinga said that the absorption delay was significant because "sugar that is normally absorbed rather quickly -- within about 20 minutes -- took over 2 hours after HCA ingestion. This delay is good because it reduces the high peaks of glucose, which otherwise would require the body to produce a lot of insulin to deal with the 'meal.'
"Finding this delayed absorption is a completely new phenomenon and one that might be useful to follow up: why is it delayed and how might this affect humans?" Wielinga reported. But he warned that "we don't know how this will translate into humans. Care must be taken because the comparable dosage we use in rats is probably way too high for humans," he added.
The 'South Beach' inference; speculation about HCA's potential in diabetes
One of the tenets of the successful "South Beach Diet" is to reduce and slow sugar absorption. In his first book, Dr. Arthur Agatston explains: "What we're concerned with here is the speed with which our bodies get at the sugars?If the body experiences a fast infusion of sugars, a lot of insulin is required. If the sugars are metabolized more slowly, the insulin is released gradually. This is a crucial difference, as far as obesity is concerned: Fast sugar is worse for you; slower is better."
Besides the implication for extra sugar being stored (as fat) rather being used effectively, Dr. Agatston notes that with large sugar infusions, the body often produces too much insulin, which then lowers the blood sugar level. When that happens, he writes, "new c
