WMS is actually more insulinemic & glycemic than your standard glucose polymer solution. Earlier research showed no difference in glycemia and insulinemia between WMS & the glucose polymer, but there are at least a couple major things to consider: a total of 300g was consumed in 30-minute intervals over a 6-hr period. The significance here is that this dosing scheme may have caused a highly efficient delivery of glucose to the intestine. Since this happened alongside a faster glucose uptake by the muscles, major increases in blood glucose were neutralized.
Now stick with me here. In the latest WMS study, a more realistic 100g was used, and better blood sampling methodology was used. Guess what? As a result of its quicker gastric emptying, WMS caused a 17.3% higher peak insulin level and a 10.9% higher blood glucose peak. Given this, any glucose intolerance or insulin sensitivity issues will definitely be amplfied with WMS. Keep in mind that when taking any CHO with protein or AA, the insulin response will synergistically elevate, and this can counteract and drive down the expected elevation in blood glucose.
