Today, the rate of obesity is a rising trend. Health experts have already told us that obesity is an epidemic causing many metabolic diseases like diabetes, heart problems, and among others. Unfortunately, if you noticed you have a poor memory lately and you’re overweight, those extra pounds you’ve gained may have been straining it. One study tested the participants and found that those with BMI higher than 25 have poorer memory compared to those having BMI less than 25.
BMI or Body Mass Index is the ratio of weight-to-height. BMI is calculated by dividing the person’s weight by the square of his/her height. The value or result after the calculation determines whether a person is underweight, normal, or obese. If the value is less than 18.5, the person is considered underweight. A value ranging from 18.5 to 24.9 is considered normal. Getting a value ranging from 25 to 29.9 is overweight, and value 30 and above is considered obese. There are many BMI calculators online including this one provided by the NIH’s National Heart, Lung, and Blood Institute, which you can pick your preferred unit either metric or standard.
In this study, researchers have found that changes to hormones in the brain caused by obesity and weight gain may harm memory. These changes also could influence people to eat more resulting to gaining more weight. The link between weight and memory problem is not a new one. However, in this new study conducted by researchers from Cambridge University in England found that adults with higher BMI’s have a worse episodic memory when tested. The study, which is published in the Quarterly Journal of Experimental Psychology tested 50 participants aged 18-35 with BMI’s ranging from 18 to 51.
Although the reason was not determined why high BMI affects brain performance negatively, the researchers believed fat rather than muscle is likely the cause. Perhaps, it may have to do with the effect of fat on insulin according to the author of the study, Lucy Cheke, Ph.D. She added if there are too many spikes of fat it cause hormones to be out of balance messing up the neurons communication inside the brain. When this process occurred, it can cause a decline in cognitive performance.
On the other hand, Lucy Cheke also pointed out it might not be the fat worsen the memory function, but that individuals with poor memory are rather likely to gain weight easily. She added that people eating their meal mindlessly can get distracted and end up overeating. Making the meal more memorable can be helpful, she added.
This is not the first study to link obesity messing up the brain. One study mentioned in Science News in 2011 where obese what scored within the impaired range based on researchers assessment. In another study mentioned in USCF Musings on Memory and Aging, researchers found that the higher the BMI, the lower the brain’s white matter. In another study reported by Fox News where researchers find that obesity increases the speed of mental decline in the long run and that there is no such thing as a healthy overweight.
These are just a few of the many studies published that linked obesity to many unhealthy consequences including the decline in cognitive function, cardiovascular diseases, diabetes, and even affect sexual health and performance. According to WebMD, obesity is linked to erectile dysfunction. Hence, if you’re someone trying to boost your erections and sexual performance, your efforts may just be in vain.
The message of this study including the previously published is clear. Lose weight and maintain ideal weight. John Gunstad of Kent State University had proven that losing weight for obese individuals improve memory function. The official finding of the study was published in the Journal of the American Society for Metabolic and Bariatric Surgery. If you’re obese or overweight, it’s time to lose that weight. If you don’t have any idea how to get started, read topics on eating whole foods. Food is medicine according to Hippocrates. However, not all foods especially today are equally healthy and nutritious.
Eating the right foods particularly whole foods can have a tremendous effect in losing weight, and even improve your sexual health, as well. If you’re skeptical, one study finds that by simply dieting can help improve mood and sex drive. And, another study also finds that healthy eating can reduce the risk of cognitive decline.
