Low-fat diets can enhance mood

  • Olivia Fens

A low-fat diet may improve a dieter’s mood, while a low-carbohydrate diet with the same calories may have the opposite effect, a new study has indicated.

Researchers from the Commonwealth Scientific and Industrial Research Organisation in Australia compared the long-term effects of a low-carbohydrate diet and a low-fat diet on mood and cognitive function in overweight and obese people.

They found that both diets resulted in weight loss. However, the study found that aspects of the low-carbohydrate diet had detrimental effects on mood and that, over the one-year study, negated any positive effects of weight loss. 

The researchers said that the low-carbohydrate diet was so far removed from normal dietary habits that the eating plan may have created a significant challenge for participants, leading to the possibility of food preoccupation, social eating impairment, and dysphoria.

Although, in the short term, participants may have been able to meet the challenges presented by the low-carbohydrate diet, over the longer term, it may have increased participant isolation, leading to the negative impact on mood state that may provide a possible explanation for the effects that were observed, the researchers said.

However, future studies were needed to address this hypothesis, the researchers concluded.

The study was published in the Archives of Internal Medicine.
