The study also found that when artificial sweeteners were used, the effect did not occur. It was like the bodies of the participants knew what was real and what was fake and was not fooled afterall. The purpose of the study was to see the effects of refueling for short bouts of exercise (30 minutes) vs an hour, and if just rinsing with the beverage had the same effect as swallowing.
Researchers not involved in the study think the effects are minimal, and athletes should just drink the stuff rather than pay for a drink you will just spit out. However, if you're trying to lose weight, this might be a good way to kick it up a notch without adding calories!

Of course there are skeptics that say there is a placebo effect but the lack of effect among the artificial sweetener test group is so interesting to me.
Did you know that diet coke drinkers are more likely to be overweight than regular coke drinkers? Hopefully they are doing some more research on the effects of these
toxic additives artificial sweeteners. I'm still a big stevia fan, so hopefully science doesn't ruin this for awhile.
