Maintain a healthy weight to reduce your risk of losing brain tissue in the temporal lobe linked to memory, hearing, speech, comprehension etc.

Researchers are of the opinion that loss of brain tissue may be due to fat causing more oxidative stress, resulting in an increase of free radicals in the body. Another possibility may be that the extra fat leads to artery disease (clogged arteries), which can limit oxygen flow to the brain. A study conducted by Swedish researchers found that women who were overweight with BMI greater than 25 throughout their adult lives were more likely to lose brain tissue in the temporal lobe compared with women who maintained a healthy weight with BMI less than 25 during their adulthood. Loss of brain tissue in the temporal lobe has been linked to memory loss, shortening of the attention span, and dementia.
