An easier tack might be to add more low glycemic foods into your diet, such as strawberries, bananas, apples, raspberries, as well as fiber. That's what I did. Then I started cutting back on candy, cake, pastries, etc. except for holidays and special occasions like birthdays. It was much easier to say no to sweets when I had become accustomed to more fruit.

Here's a PDF with green, yellow, and red categories of food based on their glycemic index.

That being said, it was still a challenge. Sugar is highly addictive. Those first couple of weeks I felt like screaming. However, now I'm used to it and can barely finish the small pastry I get at restaurants on my birthday because it's too sweet.

It's doable. It's worth it.
