I gave up soda 6 yrs ago for the most part. I actually went for 4 years without drinking one! I fell off the wagon and have one on occasion. I know that it makes you hungry, as it stimulates your appetite. Also, the carbonation causes bloating. I have seen a dietician and that is the information that I was given. FYI, Equal sweetner (aspartame) makes me hungry so I stay away from that altogether. Hope this helps!
