Savour Your Food To Lose Weight

(Reuters Health Summary)

Many of us have been warned against shovelling down our food too quickly, since not only is it not very well-mannered or attractive, it also tends to lead to weight gain and obesity. Several studies have backed this notion, and now there's one more that actually provides evidence behind the wisdom in slowing down when eating.

In a recent study out of Athens University Medical School in Greece and the Imperial College London in the UK, 17 healthy men enjoyed generous portions of ice cream, for scientific purposes, obviously. All men ate the ice cream under two conditions - in the first, they ate the it in two servings over 5 minutes; in the other, they ate it in small servings over 30 minutes.

While the participants felt just as full when they ate the ice cream in both conditions, the researchers found that when the men ate slowly, they showed higher blood levels of the hormones peptide YY (PYY) and glucagon-like peptide 1 (GLP-1) for roughly three hours after the meal. PYY and GLP-1 are both released from the digestive tract sending signals of fullness to the brain, resulting in a decrease in appetite and calorie intake.

According to one of the researchers, "Our study provides a possible explanation for the relationship between speed eating and overeating by showing that the rate at which someone eats may impact the release of gut hormones that signal the brain to stop eating,".
