I would concentrate on eating phytonutrient rich foods, such a crucferious vegetables especially, other vegetables as well, fruit, and beans. I wouldn't worry too much about counting calories right now. I know it sounds strange, odd or crazy, but there is more to weight loss than research knows at this point in my opinion. Eating a lot of phytonutrient rich foods seems to just melt the weight off of you(as long as you aren't going totally crazy on unhealthy things). So what i am saying, is there is more coming into play with weight lose than just calories alone.
And I totally understand what you are saying about the sugar, sugar is addictive, i know that firsthand. I found the only way I could break away from it, was just not eat it at all, even a some amount can send you back into a graving state of it. It truly seems to act like a drug, atleast to some people, you get a little then want a lot more.
