What's really interesting is that your taste buds actually change depending on the foods you regularly eat in your diet. If you constantly eat sweet foods - you will constantly crave them.
It's going to be hard to fight through the carvings at first but if you last about 2 weeks, your taste buds will change and you will no longer crave sweets.
If you want something sweet, try things like carrot sticks, apple slices etc.
