A study at the McMaster University in Ontario shows that obesity can age your brain by up to three years. Each 9.2 percent rise in body fat was equal to a year of brain ageing.
The most overweight people had a drop in mind test scores equal to 2.8 years of ageing. Dr. Sonia Anand who ran the study said : Strategies to prevent or reduce obesity may preserve brain function among adults. Excess flab can cause health conditions that damage blood circulation which may impact the brain.
