MSNBC: Do artificial sweeteners make us eat more?
http://www.msnbc.msn.com/id/5395440/ Quote:
As part of their study, they fed two groups of rats sweet-flavored liquids for 10 days. One group got only sugar-sweetened liquids, while the other was fed liquids sweetened by both sugar and saccharin.
After the 10 days, both groups of rats were given a sugary, chocolate-flavored snack and regular rat chow.
Both groups of rats ate about the same amount of the chocolate snack. But the rats fed both sugar and saccharin ate three times the calories of the rat chow than the rats fed only the sugar-sweetened drink.

The conclusion they try to draw from this is in dispute. Paraphrasing, they concluded it was possible that the taste buds of the rats fed the saccharin lost their natural ability to tell when to stop eating. Then they ask if artificial sweeteners might be making humans fat.
Personally, I think that's baloney. It doesn't make me mad; I just don't find it credible or consistent with my own personal experience.
Here's one possible alternative theory of what happened. The rats fed the sugary fluid got used to a higher carb intake, and the rats fed the saccharin used to a lower carb intake. When they were both given access to the real thing, the rats accustomed to eating less sugar reacted adversely, perhaps with a hypoglycemic reaction. Just one idea.
