Intentional weight loss reduces cancer incidence by lowering pro-inflammatory factors and estrogen levels, rather than by significantly altering IGF1 levels.
If you are overweight, losing weight is one of the most effective ways to lower your cancer risk. This benefit comes largely from reducing body-wide inflammation and estrogen levels, rather than just changing growth factors like IGF1. Focus on sustainable weight loss through diet or surgery, as these methods consistently show reduced cancer incidence.
Collectively, these observations suggest that estrogen and circulating pro-inflammatory factors are the major players in cancer risk decrease caused by body weight loss, unlike IGF1.
Why this rating
Based on a meta-analysis of observational cohort studies and randomized controlled trials, which provides strong but not definitive causal evidence for the specific mechanism.
