This 2014 rodent study found that fat cells released a certain hormone during exercise that produced two beneficial effects:

• the hormone increased hippocampal neurogenesis;
• it also reduced depression-like behaviors.

So if you’re feeling kinda blue,

Think your brain cells are too few?

Get your fat cells on that bike and ride!
