Development Of Tablets To Reduce The Desire For High-Calorie Food.
You're dieting, and you positive you should retard away from high-calorie snacks. Yet, your eyes muzzle straying toward that box of chocolates, and you wish there was a pill to restrain your impulse to inhale them. Such a capsule might one day be a real possibility, according to findings presented Tuesday at the Endocrine Society's annual assignation in San Diego. It would block the activity of ghrelin, the "hunger hormone" that stimulates the passion centers of the brain.

The study, reported by Dr Tony Goldstone, a consultant endocrinologist at the British Medical Research Council Clinical Sciences Center at Imperial College London, showed that ghrelin does mother the hanker after for high-calorie foods in humans. "It's been known from animal and beneficent work that ghrelin makes people hungrier," Goldstone said. "There has been a suspicion from mammal work that it can also stimulate the rewards pathways of the brain and may be involved in the response to more rewarding foods, but we didn't have indication of that in people".

The study that provided such evidence had 18 healthy adults look at pictures of unlike foods on three mornings, once after skipping breakfast and twice about 90 minutes after having breakfast. On one of the breakfast-eating mornings, all the participants got injections - some of soused water, some of ghrelin. Then they looked at pictures of high-calorie foods such as chocolate, bar and pizza, and low-calorie foods such as salads and vegetables.

The participants in use a keyboard to rate the appeal of those pictures. Low-calorie foods were rated about the same, no purport what was in the injections. But the high-calorie foods, especially sweets, rated higher in those who got ghrelin. "It seems to vary the desire for high-calorie foods more than low-calorie foods," Goldstone said of ghrelin.

That punch was especially pronounced when the participants fasted overnight before the study was done. "We separate that when you fast, you tend to crave high-calorie foods more," Goldstone said. "We mimicked that effect".

So a pastille that blocked ghrelin's activity could be useful for dieters, and several drug companies already are working to ripen one, he said. It wouldn't be something you could pop when a tempting dish appeared, because the blocking achieve would take some time to happen, but it could be part of an overall weight-loss regimen, Goldstone said. "If developed, it might have the special effect of blocking the desire for high-calorie foods," he said.

The cram results come as no surprise, said Alain Dagher, an associate professor of neurology at McGill University in Montreal, who has been studying ghrelin. In his research, MRI scans of animals found that "ghrelin increases the intellectual answer to food," Dagher said. "So, it's not surprising that a individual injection in humans supports a shift to high-calorie foods in general".

Dagher is continuing his studies. "We've been distressing to get more specific about exactly how ghrelin acts on the brain, which brain regions it affects and how those gear translate to eating," he said vito mol. Ghrelin might not play a role in causing obesity, but it might act to withhold people obese by reducing their ability to lose weight, Dagher said.
