Belly fat is bad for thinking. Here’s all you need to know

A new study looked at findings that could lead to new treatments that help maintain mental flexibility in ageing adults with obesity, sedentary lifestyles, or muscle loss that naturally happens with ageing.

Making a New Year’s resolution to work out more and eat healthier may be a good idea, not only for your overall health but also to maintain healthy brain function.

Researchers have found for the first time that less muscle and more body fat may affect how flexible our thinking gets as we become older, and changes in parts of the immune system could be responsible.

These findings could lead to new treatments that help maintain mental flexibility in ageing adults with obesity, sedentary lifestyles, or muscle loss that naturally happens with ageing.

The study was published in the journal of Brain, Behaviour, and Immunity.

The study, led by Auriel Willette, assistant professor of food science and human nutrition, and Brandon Klinedinst, a PhD student in neuroscience, looked at data from more than 4,000 middle-aged to older UK Biobank participants, both men and women.

The researchers examined direct measurements of lean muscle mass, abdominal fat, and subcutaneous fat, and how they were related to changes in fluid intelligence over six years.

Willette and Klinedinst discovered people mostly in their 40s and 50s who had higher amounts of fat in their midsection had worse fluid intelligence as they got older.

Greater muscle mass, by contrast, appeared to be a protective factor. These relationships stayed the same even after taking into account chronological age, level of education, and socio-economic status.

“Chronological age doesn’t seem to be a factor in fluid intelligence decreasing over time,” Willette said. “It appears to be a biological age, which here is the amount of fat and muscle,” he added.

Generally, people begin to gain fat and lose lean muscle once they hit middle age, a trend that continues as they get older. To overcome this, implementing exercise routines to maintain lean muscle becomes more important.

Klinedinst said exercising, especially resistance training, is essential for middle-aged women, who naturally tend to have less muscle mass than men.

In this study, in women, the entire link between more abdominal fat and worse fluid intelligence was explained by changes in two types of white blood cells: lymphocytes and eosinophils. In men, a completely different type of white blood cell, basophils, explained roughly half of the fat and fluid intelligence link.

“If you eat alright and do at least brisk walking some of the time, it might help you with mentally staying quick on your feet,” Willette said.
