Also, excuse the double reply, but there are simple solutions to also help push society in the right direction. For instance requiring employers over 'x' employees (let's say 1000) to provide free access to a specified minimal set of exercise equipment and grant employees at least 'x' hours per week of paid exercise time which must be spent within this area exercising at a reasonable intensity (in other words not taking an hour break to go play on your phone in the gym).

Other things would be to offer a 100% tax credit for things like gym memberships. If this actually incentivized people, then it'd probably pay for itself through better health outcomes for society. It could also be paid for by adding a health tax, such as already exists on cigarettes, to e.g. highly processed foods, candy, and cola.

Similarly, the FDA should have some sort of an accreditation that restaurants and other food services can apply for that confirms some standard of minimal healthfulness of their food. This accreditation would be extremely critical since, in general, just dumping salt and sugar into food makes it more addictive, which increases margins, so when you go for health - you do so at profit loss. Such an accreditation could help combat this by giving people something to look for.
