" Consuming fatty foods makes the brain less able to distinguish when the body is full, according to new research.  In a study on rats, creatures who were fed fatty foods were less sensitive to a hormonal &amp;quot;stop eating&amp;quot; signal than rats on a low fat diet, when presented with high calorie, high fat snacks for consumption.  The research adds new weight to claims that fatty foods are worsening the obesity situation in the UK and suggests that eating high calories foods starts a perpetuating cycle of unhealthy overeating.  Cholecystokinin (CCK), the hormone that tells the brain to stop eating, is released by the body to tell the brain when to stop eating. Previous studies with human subjects showed that those on a high fat diet have more CCK in their bloodstream but are less responsive to it.  They typically report feeling increased hunger, declining fullness and eating more than those on a lower fat diet.  The study concluded that rats on the high fat diet ate on average 40 per cent more than their &amp;quot;normal&amp;quot; counterparts when presented with fatty snacks.  \u00A9 Adfero Ltd "^^<http://www.w3.org/2001/XMLSchema#string>
