Cognitive impairment has long been associated with obesity in scientific research, however, very few are aware of the fact that being overweight can be a reason behind memory loss disease such as Alzheimer’s and Parkinson’s. Research shows that, overweight women are more vulnerable to stroke and dementia as compared to men. The fat accumulated around the hip is the major cause, which eventually makes women less active, and at an older age, even immobile. This affects their eating habits greatly. There is a very sharp and strong relation of obesity with poor memory and decreased cognitive ability.

A study conducted at Northwestern Medicine reported that as the body mass index – BMI, increases even by one point then consequentially the score on the mental status drops by one point. There are so far many varying reasons to justify memory loss, however, in each case the affecting factors were different. Such as weight gain can be a cause of memory loss or memory loss is due to obesity. Even though it’s not clear, evidence shows the inversely proportional relationship between memory loss and body weight. Obesity is considered as the major cause for many other potentially fatal diseases like diabetes, heart stroke and many neurodegenerative disorders. In this regard, it’s much easier to blame that the extra fat in your body can have detrimental effects on your mental health.

However, not to forget it can have an opposite effect as well as due to a weak memory a lot of people can’t maintain a proper eating schedule. They may forget to have dinner on time or skip lunches. As people age, their memory weaken naturally as well and their appetite begins to deplete as compared to their younger days.

Another investigation published in Journal of the American Geriatric Society suggests that the fat stored around the hips and waist can cause the secretion of a hormone cytokines, which can be a reason behind intense inflammation that deters cognition. The fat in your body can also limit your blood flow to the brain, causing a disturbance, impairing brain functionality. The accumulation of fat plaques is also linked with memory loss conditions like Alzheimer’s disease. This recent study advocates that weight loss is essential to sharpen memory and restore your cognitive functionality. There are other associative studies, which ensure a normal BMI or considerable weight loss can indeed help reverse episodic memory loss related to diseases like amnesia. A decrease in body weight can be a reason for improved memory, which was evident after brain scanning some participants in the study. It is also been confirmed that obese people after bariatric surgery performed better on memory challenges as compared to when they were fat.

Connection between Diets and Memory Loss

A variation in your diet can be a reason behind memory loss. A lot of people don’t take a balanced diet regardless of their weight. Even some people with normal weight can be affected by deadly mental impairments if they are not taking the right amount of nutrients. For instance, many people reduce their carbohydrate consumption to lose weight, but this can cause memory loss too. Carbohydrates provide energy to brain cells; absence of carbohydrates in the body means lack of energy, which means a lack of brain cell production, hampering your cognitive performance.

Side Effects of Weight Loss Pills on Memory

In order to lose weight, people choose a more convenient and that is taking diet pills. It is important to understand that taking diet pills regularly, especially the ones with statin labels can damage cognitive ability.

So, as you can see there is a strong link between memory loss and body weight.
