I follow a low-carb/WW approach. I eat less than 50 gms carb a day including vege and other high fiber carbs. Sometimes I die for a sweet treat!
I found the book Unbelievable Desserts with Splenda has been , well unbelievable in satisfying my sweet tooth.
The desserts are all low fat and low cal - under 200 cal for big servings and reduced carb. The coffee drinks are great for under 10 carbs as is the pumpkin custard and the lemon mousse.
When I "splurge" I go up to 15 carbs on my treats (regular desserts are like 60 and up) and I have made the cheesecake (15 carbs and no sugar) and 2 of the coffecakes (= 1 bread per serving) and they were GREAT. You would think you were cheating big time. The author does use some sugar occassionally but where I used to use cups to get real desserts for my splurges she uses a couple tablespoons with the splenda ( the no-cal sweetener) and the stuff tastes just like the super high carb stuff - not the low carb diet tasting stuff. Definitely worth getting.
You can get the cheesecake recipe at:
marlenekoch.com by going to the BOOK page and scrolling under the book cover (and do try the frosty mocha while you are at it)Unbelievable Desserts with Splenda

Thanks for the site, I'll have to check it out! You should also check out the recipe section here and see what's there--all of it is low carb or Splenda based!
