These reductions are expected to come primarily from lower cardiovascular disease (CVD) mortality and improved outcomes in other conditions, assuming clinical trial results translate into real-world effectiveness. This has major implications for life and health insurers, potentially reshaping claims and lowering costs for longevity-related products. However, GLP-1 drugs have not yet demonstrated long-term improvements in population-level metabolic health. The US, with the highest adult obesity rate among developed countries (40.3%), is projected to exceed 55% by 2050 without intervention. GLP-1 drugs like semaglutide and tirzepatide have shown substantial weight loss in trials, but real-world effectiveness may vary. In baseline projections, mortality reductions are 4% (US) and 3.2% (UK), while pessimistic scenarios suggest smaller impacts (2.3% and 1.8%). Risks include discontinuation due to lack of lifestyle support and concerns over muscle and bone loss. For insurers, while mortality and critical illness portfolios may benefit, longevity portfolios could face financial pressure due to longer lifespans and extended pension payouts
