And why is obesity rising so quickly in nearly all first world countries but particularly in the US? Most of the research points at three reasons: 1. Modern food systems - fast food, frozen boxed food, and a severe lack of access to healthy whole foods 2. Income inequality - Obesity rates are far higher in lower income people and healthy food is far more expensive 3. Work culture - We work far more hours and far less physical jobs. Less hours to exercise and more cost to exercise. Sure individuals can find ways around all these issues but the more roadblocks we as a society put in people's way the more that will fail. Which is is exactly what the OP is talking about, major scientific and economic issues cause far worse health outcomes.
