Obesity linked to inflammation & impaired brain function

A mouse study has found that obese mice had high levels of interleukin 1 in both their blood and their brains, and this was associated with:

  • high levels of inflammation,
  • low levels of a biochemical important to synapse function, and
  • impaired cognitive function.

Moreover, when fat was removed from the obese mice, interleukin levels dropped dramatically, and cognitive performance improved.

Putting obese mice on an exercise program had a similar effect, even though they didn’t lose weight — but they gained muscle and lost fat.
