one study found that muscle loss and the 4 of body fat around the abdomen are associated with a decline in fluid intelligence. this suggests 
the 5 that lifestyle factors might help prevent or 6 this type of decline.
the researchers looked at data that 7 measurements of lean muscle and abdominal fat from more than 4,000 middle-to-older-aged men and women and 8 that data to reported changes in fluid intelligence over a six-year period. they found that middle-aged people 9 higher measures of abdominal fat 10 worse on measures of fluid intelligence as the years 11 .
for women, the association may be 12 to changes in immunity that resulted from excess abdominal fat; in men, the immune system did not appear to be 13 . it is hoped that future studies could 14 these differences and perhaps lead to different 15 for men and women.
16 , there are steps you can 17 to help reduce abdominal fat and maintain lean muscle mass as you age in order to protect both your physical and mental 18 . the two highly recommended lifestyle approaches are maintaining or increasing your 19 of aerobic exercise and following mediterranean-style 20 that is high in fiber and eliminates highly processed foods.
