How much of the rise do the listed later on (endurance athletes, obesity, sugary drinks, sedentary lifestyle) explain the relative youth rise? After all, some of this was an issue in 2006 as it is in 2026. Does it explain most of the relative rise, or is there a major missing piece / a mystery still to be explained? I doubt the % of endurance athletes changed meaningfully population-wide, to be a major contributing factor, for example.

You'd be surprised. COVID-19 fundamentally altered a lot of people's habits.

I had to have a good read of the article and put the content in ChatGPT for further more detailed analysis. I still can’t infer a single thing about how I should be surprised or how people’s habits changed, so feel free to enlighten me!

Food delivery is now an "essential" for more people than it ever was before. Doordash/Uber Eats is how a weirdly large amount of people eat in general.

The rate of increase in childhood obesity went up during covid.

You realize that is far too recent to show up in cancer death rates for under-40 year olds right? It takes 10-15 years for a change-in-behavior to show up in incidence and even longer for deaths. As a classic example, see the shift (i.e. the delay) in curve of reduced smoking and reduced lung cancer.
