Scientists Find How Obesity Gene Works, A Clue To Treatment
New brain clue to obesity
Junk food could trigger brain signals, making you eat even more
Eating junk food could ‘overload’ certain parts of the brain that control what you eat, urging you to consume even more calories, found a new study.
Scientists from the University of Wisconsin-Madison discovered a particular pathway in the brain that can becomedisrupted by poor diets.
The‘broken’ signalling systemthen affected how much food was eaten, suggesting it is responsible for regulating how much you normally eat.
Studies found that a particular protein produced in the brain was‘switched on’when mice were fed a high-sugar and high-fat diet. Once the protein was activated, the mice startedeating even morefood.
The researchers then managed toblockthe protein pathway so even when mice ate a bad diet, they did not overeat and maintained anormal weight.
Dr Dongsheng Cai, who led the research, said the discovery of the pathway could lead toanti-obesity drugs.
‘Theultimate goalwill certainly be to identify a selective and effective suppressor of the pathway to target related neurons,’ he said.
