Question for people who have successfully lost weight, about Sugar vs Artificial Sweetners?

I have lost over 70 lbs. this year. I cut pure sugar and started using Splenda. Unfortunately, I cut out sodas all together. It seems to have helped me tremendously. Here is a great article for you to check out. http://www.nakedfoodcooking.com/sugar-substitutes/---but my advice is....I haven't been healthier since giving up sugar, and with the sweetener i use I don't miss it. Good luck, I'm rooting for you.
