At the end of one year, C-reactive protein reduced by 36.1 percent in the diet-alone group and by 41.7 percent in the diet and exercise group. Interleukin-6 decreased by 23.1 percent in the diet group and 24.3 percent in the diet and exercise group.
McTiernan and colleagues found a mild dose response, as there were greater reductions in these measures among women who lost at least 5 percent of their body weight. They also found that exercise alone, without a dietary weight loss component, had little effect on inflammation markers.
“This study adds to the growing understanding we have about the link between obesity and cancer, and it appears we can affect inflammation directly through nonpharmaceutical means," said McTiernan.
