Yes......although I haven't totally cut them out. I also try to use Stevia instead of splenda because it's from a plant. The research from several studies have shown that artificial sweeteners may save calories while being consumed, but the chemical impacts actually make us crave sweets/carbs that much more so that the end result is that people often end up eating more instead of less when large quantities of sweeteners are consumed. With that said, I don't think the occasional diet soda (and by occasional, I mean maybe 1 per day) or a little Splenda on your oatmeal will sabotage your efforts. Have you noticed that a lot of these studies use vast quantities of products so it's sometimes hard to relate it to our own habits!
