A recent study in Beijing announced that air pollution was related to increasing obesity rates in rats. Although this is alarming, the real question is, “Does this mean humans are gaining weight from air pollution?”.

This study doesn’t answer that question and for now the answer remains what it has been. Obesity is a multifactorial and complex disease, we know that living in today’s obesogenic environment paired with genetics, lifestyle and dietary habits are all possible contributing factors for obesity in humans.
