As an experiment of one, I found that for me, low-cal sweeteners don't affect my blood sugar or my weight. They don't even make me crave more. When I first started LC I would make single-serving muffins in a mug - but the similarity to sweet bread would have me craving more. Four single-serving muffins - even without sugar - is just too much for a diabetic.

Since my main craving has long been bready things, I stick to other desserts that don't talk my brain into having more. I have a diet cola almost every day with my lunch. I make sugar-free jello & panna cotta - no real difficulty in eating just one serving.
