Researchers documented that a potent brain-derived neurotrophic factor (BDNF)¹ was significantly boosted by three months of aerobic exercise, and the higher its level the less a person wants to eat and the greater their weight loss. This is the first time BDNF levels have been linked to appetite suppression -- a significant finding.

This study is important for several reasons. First, it explains another angle on how aerobic exercise helps weight management. I have previously reported that aerobic exercise also restores the function of leptin receptors around your body, helping this key weight loss hormone work better. I have also explained that exercise helps release beta-endorphins, your "runner's high" hormone that is key to relaxation.

This new information expands on the important benefits of aerobic exercise as BDNF is a powerful protector of brain cells and stimulator of new brain cell formation, factors that have a direct bearing on your mood and preservation of your brain's function.
