A new study finds that fat-filled foods may damage the region of the brain responsible for regulating a person’s appetite, which scientists say could account for why overweight people struggle with sticking to a diet plan.

Announced at the British Science Festival, the study found that a diet rich in saturated fats leads to damage to the brain’s hypothalamus, a key region involved in controlling appetite. The findings suggest that saturated fats may have a direct impact on the body’s ability to stick to a diet.

The hypothalamus is a small area at the base of the brain containing neurons that control the amount of food we ate and the energy we expend. However, this control breaks down in obesity – the system appears not to work and we do not really know why this happens.

To help answer the question, researchers 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. In the study, researchers found that genes and proteins changed in response to a high-fat diet and that these changes are normally associated with damage in the brain, indicating that damage had occurred in the hypothalamus in mice that ate a diet high in saturated fat.

Researchers warn against a high-fat diet over a protracted period, but not worrying over an occasional unhealthy treat. The key is to avoid excessive weight gain and to eat sensibly in the first place. A separate study released in January found that people who consumed diets high in trans fats were more likely to have brain shrinkage and scored lower on thinking and memory tests, compared to people who followed a healthy diet, low in trans fats and high in vitamins.
