A meta-analysis of nine studies following 199,425 adults with obesity found that moderately to very active people had a 21% lower risk of death from any cause and a 24% lower risk of cardiovascular death than insufficiently active people. The association with cancer deaths was not statistically significant.

What it shows: A strong signal but not proof of cause: results pooled from nine studies that followed 199,425 adults with obesity rather than testing exercise on them, so active people may have been healthier in other ways. The cancer finding rests on only two studies and could still be chance.Meta-analysis · BMC Public Health
