Some biological-ageing measures estimate age-related changes in cells from patterns like DNA methylation. In a roughly three-year randomized trial, omega-3 modestly slowed changes in several of these measures, on the order of a few months, but we don't yet know whether that means people actually age more slowly or live longer. These ageing clocks are research tools, not a proven measure of a longer life. The strongest everyday advice for healthy ageing is still exercise, especially strength training.

Visceral fat, the fat deep around your organs, can be high even in lean-looking people and is linked to higher risk of heart disease, diabetes, and some cancers. The clearest levers to reduce it are regular exercise, enough sleep, a whole-food diet without constant overeating, and limiting alcohol. The episode's distinctive angle is everyday chemicals, BPA, phthalates, and PFAS in plastics, receipts, and non-stick pans, which may affect hormones over time; cutting exposure is low-risk and reasonable. It also covers supplements and weight-loss drugs, where the science is more mixed. Some claims are stated more strongly than the evidence, but the core levers are well-supported.
