Low-carb diet may help you live longer, reveals new study

A keto diet turns the body into a fat-burning machine and is usually known for reducing weight, improving health and performance and there have been over 20 studies that prove this, according to healthline.com, a website that provides health information.

The research has many caveats for humans eager to utilize diet to improve their odds of maintaining cognitive ability-it involved a single strain and sex of mice living in an environment where it's easy to control every aspect of the diet. While calorie restriction has been shown in several studies to slow aging in many animals, Ramsey was interested in how a high-fat diet may impact the aging process. Analysts noted that it can raise the concentration of beta-hydroxybutyrate acid (BHB) in the body that improves memory. The keto diet is so ultra-low in carbs it also causes ketosis, whereas other diets can be low in carbs but not produce this.

Researchers from University of California Davis in the USA split mice into three groups: a regular rodent high-carb diet, a low carb/high fat diet, and a ketogenic diet (89-90 per cent of total calorie intake). Another group of mice underwent memory testing at both middle age (one year old) and old age (two years old).

Whether you want to call it the Atkin's Diet, Paleo or simply "Keto", there have been plenty of variations on this way of eating.

The researchers then tested the mice at various ages in tasks such as mazes, balance beams, and running wheels.

These two new companion studies have examined the long-term effects of a ketogenic diet on mice.

The diet increased their memory, coordination and strength during old age. The mechanism behind this could be the fact that ketogenic diet induces protein acetylation in the mice liver and muscles. But two new United States studies published in the journal Cell Metabolism explore other benefits of the diet: it improves memory and extends lifespan, at least in mice.

Additionally, the mice on the ketogenic diet explored more.

"The results surprised me a little", said nutritionist Jon Ramsey, senior author of the paper that appears in the September issue of Cell Metabolism. The new study was conducted on mice models, and results showed a 13 percent increase in median life span for mice that were put on a high fat diet in comparison to mice that were given a high carbohydrate diet. In humans, that would be seven to 10 years.

"At a fundamental level, humans follow similar changes and experience a decrease in overall function of organs during ageing", Ramsey said.

The first study, conducted by the Buck Institute for Research on Aging, found the ketogenic diet improved memory and preservation of brain function, with older mice attaining better memory function than younger mice.

Tests on the mice checked for heart function and gene regulation changes through DNA analysis.

The ketogenic or keto diet has been favored by a number of celebrities such as Gwyneth Paltrow, Mick Jagger, and Kim Kardashian. That's really remarkable, ' he added. "The two studies reinforce each other, because they both show the same global effect on healthspan". The Verdin lab is now exploring beneficial effects of a similar ketogenic diet in a mouse model of Alzheimer's disease.
