SG...I think you should allow yourself to eat a healthy diet which of course needs to include some fats and sugars. As long as you're getting these from natural sources (eg through dairy) then what's the problem? You're teaching yourself healthy new eating habits and I think it's great. If you just went cold turkey from things like fats and sugars, it's really is a diet and not a change of lifestyle, which from where I'm sitting is what you're doing. Of course, we all know that relevant research says that's the way everyone should go about losing weight rather than going on a 'diet'.
Good on you for eating chicken. (you know the hormones make your boobs grow right?)
