Artificial sweeteners 'can make you eat more'

Consuming food and drink containing artificial sweetener makes you feel hungry and eat more, research suggests.

Experts at the University of Sydney studied the effects of artificial sweeteners on the brain in regulating appetite and in altering people's taste.

They found that fruit flies fed a diet with artificial sweetener ate 30% more calories when they were then given naturally-sweetened food. Experts believe the sweetener prompts the brain to believe not enough calories have been taken in.

Associate professor Greg Neely, from the University of Sydney, said: "After chronic exposure to a diet that contained the artificial sweetener sucralose, we saw that animals began eating a lot more.

"When we investigated why animals were eating more, we found that chronic consumption of this artificial sweetener actually increases the sweet intensity of real nutritive sugar, and this then increases the animal's overall motivation to eat more food."
