Not quite what you are asking for, but I got in the habit of having whole fruit for dessert after most meals instead of soda, juices or sweets. It seems that over time, if you avoid soda and sweets, fruit tastes better and better.

I'm not going to lie and say that I enjoy fresh berries more than I would enjoy a chocolate milkshake, but I find I can live with the substitution.

Of course fruits still contain sugar but it's probably a much healthier way of consuming sugar than with more refined/concentrated sweet foods.
