Faulty brain circuit helps explain obesity–depression link

The team found that feeding mice a high fat diet disrupted the circuit, which led not only to weight gain but also to signs of anxiety and depression on standard behavioral tests.

When the researchers used genetic techniques to restore the normal functioning of nerve receptors in the circuit, this resulted in weight loss and eliminated the animals’ signs of anxiety and depression.

A recent study in mice has found that eating a high fat diet may disrupt a newly discovered neural circuit that affects both mood and appetite.
