The 70% and 500% numbers were in comparison to gains in the other group.

Researchers found that the diet soda drinkers had waist circumferences 70 percent greater than those who non-diet soda drinkers. And people who drank diet soda the most frequently -- at least two diet sodas a day -- had waist circumferences that were 500 percent greater than people who didn't drink any diet soda, the study said.

OK, let's say one group experienced an average waist gain of 1.5 cm and let's say the second group saw an average gain of 7.5 cm. Then one would say that the second group experienced waist circumference increases that were 500 percent greater than those of the first group.
