Exercise may reset brain chemicals regulating appetite

That’s the conclusion of a study published Tuesday in PLoS Biology journal.  The study found obese rats that exercised ate less during the 12 hours following their workouts than sedentary rats.  The researchers also found that exercise re-established the ability of leptin (hormone that has a central role in fat metabolism) to signal the brain to stop eating in the obese rats and restored some key signaling molecules to levels found in lean rats.

Take home point: exercise will regulate appetite.  Note in this study – exercise didn’t change appetite in LEAN rats. That makes sense because their brains were already doing a good job of maintaining a healthy weight.
