This Is What Weight Loss Does To Your Brain

The study, which focused on people who underwent bariatric surgery, found that the procedure had positive effects on the brain, but other research has shown that less invasive weight loss strategies can also reverse brain damage related to body fat. Obese people are estimated to be about 35% more likely to develop Alzheimer’s compared to thoes of a normal weight.
Some research suggests that body fat ups the number of proteins in the brain that trigger a cascade of events that predispose someone to the disease, and other research in mice has suggested that fat cells release a substance called interleukin 1, which can cause severe inflammation and, in turn, gunk up the brain.
