In the induction phase, drinks using the artificial sweetener aspartame are not allowed. What kind of diet drinks can I drink then?
Dr. Robert Atkins agrees with many nutritionists that aspartame inhibits ketosis. Definitely try to stay away during induction. So as far as the induction period goes, id advise to stay away. You might also want to limit caffeine as well. Keep in mind aspartame affects people differently so some people can have aspartame without any problems. Your best bet for diet drinks are those made with Splenda. Diet Rite is a good choice.
