High-fat, Low-carbohydrate Diet May Increase Memory, Lifespan

For people seeking to lose weight, following a high-fat, low-carbohydrate diet could be of great help, proposes a new study. If findings of this new study are anything to go by, then eating a ketogenic diet may help in weight loss. What’s more, it may also increase longevity and improve memory and physical strength, claims the study.

High-fat, Low-carbohydrate Diet May Increase Memory, LifespanIf you didn’t know already, the ketogenic diet is a adequate-protein, high-fat, low-carbohydrate diet that is known to cause weight loss and provide numerous health benefits. Several studies show that this type of diet can help a person lose weight and improve health, and as well may even be effective against diabetes, cancer, epilepsy and Alzheimer’s disease.

Now researchers from the University of California – Davis, found in an animal study that the ketogenic diet,often termed keto (having high-fat, low-carbohydrate and low-protein), can help weight loss seekers to lose weight and may be the key to increased memory and longer lifespan.

In an experiment with mice models, the researchers noticed a 13 percent increase in median lifespan for the animals on a high fat diet, compared to the rodents on high carbohydrate diet.

“In humans, that would be seven to 10 years. But equally important, those mice retained quality of health in later life,” said nutritionist and senior author of the study Jon Ramsey from the University of California – Davis.

For the study, mice were split into three diet groups: a high-carb diet, a low carb/high fat diet, and a ketogenic diet. The rodents were then put through health, fitness and memory tests and compared with mice in control diet group.

Apart from shedding body weight, the older mice that ate the ketogenic diet exhibited memory improvements than their younger counterparts, the researchers found. “The older mice on the ketogenic diet had a better memory than the younger mice, which is really remarkable,” they said.

The researchers hypothesise that consuming a ketogenic diet boosts the secretion of the ketone body beta-hydroxybutyrate acid (BHB), the elevated level of which helps enhance memory and extends lifespan.

“This study indicates that a ketogenic diet can have a major impact on life and health span without major weight loss or restriction of intake. It also opens a new avenue for possible dietary interventions that have an impact on ageing,” Ramsey said.

The study was detailed in the journal Cell Metabolism.
