I’ve had acquaintances waste away trying to delay cancer death. Hospice is not fun, so I’d rather go out on my own terms.
Plus, any kind of money making scheme I’d think of is likely going to end up like the “aim for the bushes” scene in The Other Guys.
For me what made a huge difference was adding acid, specially for stews. A hearty splash of vinegar or soy sauce while stewing, or even a dash of lime just before serving takes it from “meh” to “seconds please!”.
