As we have reported, the link with fracking chemicals and serious adverse health problems has been demonstrated in numerous scientific studies over the past several years. In this recent study on fracking chemicals researchers examined the possible link to weight gain and obesity and found that the number and size of fat cells increase when exposed to even diluted mixtures of fracking chemicals.
