Environmental hazards, such as modern polluting agents, in particular the polycyclic aromatic hydrocarbons (PAHs) produced by any combustion process (even a scented candle) rank high among the lifestyle factors apt to promote weight gain, obesity, prediabetes and Type 2 diabetes. These compounds may disrupt the lipolysis process, i.e. the transformation of body fat into energy, making our bodies more reluctant to destock fat.
