I gave up most sugar two years ago. About three months after I cut sugar out of my diet, I had bloodwork done. My numbers were great. That has kept me on the path -- I really want to avoid the late-onset diabetes that my (a little older sister) has been dealing with.
I have something sweet very occasionally, but don't have any urge to continue with it as long as the use is very occasional. For my birthday, I made a cake with buttercream icing. The cake was going stale, I was eating it so slowly, and I tossed it out. Recently, I also brought home a tin of cookies from the office that was a freebie and that noone else wanted. I didn't want the cookies -- but I really wanted the tin. So I tossed the cookies out. I hate to waste the food, but don't see the value in passing on food that isn't good for anyone.
I find I have to keep working at eliminating sugar sources. I was eating low fat yogurt with fruit in it, but I couldn't tell from the labelling how much sugar was being added by the fruit and how much by added sugar. I bought some little food containers, and started adding frozen fruit (no sugar) on the bottom, topping it with low fat Greek yogurt, and they were much less sweet. So, the answer was much more of the sweetness was coming from the added sugar. It took a couple of days for my tastebuds to adapt, but I like this much better.
People have with the best of intentions told me about substitutes for baked goods. But my reason was to replace the sugar with food with nutritional value. So my breakfasts are some kind of low fat protein and vegetables. (I like eggs and I like fish. I've recently switched to egg white scrambles, so I can have eggs more often.) My snacks generally focus on protein and vegetables and some fruit. I haven't lost any weight, but I have lots more energy, better mood.
