High fat, low carb diet may combat schizophrenia

Melbourne | A diet which is high in fats but low in carbohydrates, preferred by some body-builders, may be effective in treating schizophrenia, a new study has claimed. Researchers at the James Cook University (JCU) in Australia have discovered that feeding mice a ketogenic diet, which is high on fat but very low on carbohydrates (sugars), leads to fewer animal behaviours that resemble schizophrenia.

The ketogenic diet has been used since the 1920s to manage epilepsy in children and more recently as a weight loss diet preferred by some body builders. The diet may work by providing alternative energy sources in the form of so-called ketone bodies (products of fat breakdown) and by helping to circumvent abnormally functioning cellular energy pathways in the brains of schizophrenics.

Most of a person’s energy would come from fat. So the diet would consist of butter, cheese, salmon, etc. Initially it would be used in addition to medication in an in-patient setting where the patient’s diet could be controlled, said Zoltan Sarnyai from JCU.

The findings show that mice on a ketogenic diet weigh less and have lower blood glucose levels than mice fed a normal diet. It’s another advantage that it works against the weight gain, cardiovascular issues and type-two diabetes we see as common side-effects of drugs given to control schizophrenia, Sarnyai added.

Schizophrenia is a devastating, chronic mental illness that affects nearly one per cent of people worldwide. There is no cure and medications used to alleviate it can produce side effects such as movement disorder, weight gain and cardiovascular disease.
