Dark chocolate is something I treat myself to occasionally, when certain chocolates are on sale, in a few stores around here. Something I have no willpower with are brownies - those ones I make with 8 oz unsw chocolate and 8 oz butter (named Palm Beach Brownies, I guess because of the richness) are so incredibly good, I don't even make them anymore, unless I'm taking them somewhere, otherwise, they are in the next room calling me. The only other sweet that I can think of that I have no willpower with, are those Chocolate Chip Coconut Macaroons, with the layer of dark chocolate spread on the bottom - another one I only make to take somewhere, and eat only a few that way.
And something that I used to eat, that I only treat myself to occasionally now, is Thai Curry. I used to make 2 or 3 a week (which means many more servings, for one, and often this would be for breakfast and lunch, as well), and with all that coconut milk/cream, and the white jasmine rice, definitely not something I should have been eating so much of! And then there were those Thai soups, with the coconut milk. When I reduced this greatly in my diet, (this was way back, when I went on my Indian food kick, so I was buying a lot of lentils, instead of jasmine rice) I lost about 45 lbs. I still treat myself to it occasionally, but I don't keep 3 or 4 varieties of curry paste in the freezer, like I used to.
Then there are those sweets I'll be eating too many of by around July 4th - those Sunsugar tomatoes. But then, they aren't as bad for me as these other things I mentioned.
