What if we added some sort of additive to the sugary drinks that made people become fat and get tooth decay, wouldn't that dissuade them? (/s fwiw, I don't think there's a "solution", people should be free to mess with their health)

Strongly disagree. That's the entire point of these kinds of questions.

Without a counter-argument it just becomes a statement of faith, of the "it's so obvious that god exists that I don't have to prove it" variety. You're entitled to your opinion, but expecting others to take your word for its value isn't going to get you anywhere.
