Diet rich in saturated fats may damage the region of the brain responsible for regulating a person's appetite, finds study.

"However, this control breaks down in obesity - the system appears not to work - and we don't really know why this happens," she said.
To help answer the question she used a strain of mice that is susceptible to weight gain and put half of them on a high-fat diet, and the other half on a normal low-fat diet.
After just three days they saw changes to the proteins [of the hypothalamus], and to the genes after one week.
"Our experiment reveals a potential mechanism whereby a high-fat diet that is energy dense can damage or injure the hypothalamus," she said.
"These changes may lead to the break down of the energy-balance centres in the brain, and so encourage weight gain and obesity.
