You say force a diet change on a patient. OP certainly meant forcing a diet change in the input of American factories. Sugar can be found in fruits. That's the right place. If you need some, use fruits, maybe alcohol. Everything else can be slashed. No sugar in prepared meals anymore. No sugar in pasta anymore. And most of all, no sugar in water. Sugar input makes more damage than cocaine today.

We can call it the Prohibition II. There will be underground bars with sick people binging on sugar. We can change the shape of sugar to prevent restaurants from adding it to food. We can make it bitter. Absolutely need sugar? Eat that lemon-tasting block. We can call it The War On Sugar.

people are so addicted to sugar that you are getting downvoted and maybe even flagged.

I like "The War on Sugar" idea (even tho I went out 1 hour ago to buy lots of chocolates and candies, as I'm an addict).
