If you're a sugar user you may be craving your daily fix of sugar more than just food.
First step I would recommend you try is getting all sugar other than naturally occurring sugars such as milk sugars in dairy products. If you must use sugar avoid refined white sugar and HFCS like the plague, they're not natural sugars and your metabolism wasn't designed to handle them in large quantities on a regular basis.
If you just need to make something sweet try stevia, very sweet and no sugar or calories.
Other than that have you just engaged yourself in other thinking activities to dominate your thinking, I frequently get involved in some intellectual activity to the extent I completely forget to eat at all. Basically just think about thinking intensely about some project or something you are interested to push thinking about food to the back of your mind instead of letting it be in the forefront.
Run this stuff by your AI and examine it to see if it suits your lifestyle and also get other suggestions to approach the problem.
