But the scientists said in obese people the second signal was delayed and weaker. The researchers believe the brain's delayed response to food could be caused by obesity. Eating slowly could be particularly helpful for obese people whose fullness signals are weaker, according to the researchers. Nearly a quarter of Americans and a growing number of Europeans are obese. It is a chronic condition which results from a combination of genetic, metabolic and behavioral causes.
Excess weight increases the risk of other illnesses such as heart disease, diabetes and cancer.
