Weight Loss Can Improve Memory



A further incentive for weight loss has been uncovered by researchers in Sweden, their study has shown that memory impairment as a result of obesity is not irreversible.


A study has found that obese women who lose weight have improved brain function. The research carried out in Sweden took 20 overweight, post-menopausal women and put them on one of two diets, the paleolithic or the Nordic Nutrition Recommendations. The data collected was combined and it was found that overall the women's BMI had dropped from 32.1 to 29.2, placing them below the cut-off for obesity and their average weight had dropped from 85 kg to 77.1 kg.

Memory was tested using a functional MRI and it was found that the women's episodic memory improved after the weight loss. The MRI showed that during the encoding stage of memory the activity of the brain was increased, as a result when it came to recalling the information the women were able to do so at a faster rate. 

This research suggests that memory impairments as a result of obesity can be reversed with weight loss, giving being a healthier weight an extra incentive.
