I am new to the Atkins diet and have a question about artificial sweeteners. I dropped a quick 4 pounds and now, although I am following the diet strictly (no cheating, I swear!), have not lost any more weight and am no longer in ketosis. I had been when I last tested. Dr. Atkins says that aspartame might be the reason. Does anyone know if the artificial sweetener sucralose has the same effect as aspartame? I have been drinking many things with aspartame as well as sucralose. Should I cut out both from my diet or is aspartame the only culprit? Help! I am very discouraged.
