You should seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. Indeed, the level of chemicals in the environment is purported to coincide with the incidence of obesity, and examples of chemicals that appear to cause weight gain by interfering with elements of the human weight control system—such as alterations in weight-controlling hormones, altered sensitivity to neurotransmitters, or altered activity of the sympathetic nervous system—are noted.
