I think the biggest impact that diet soda has it the high salt content dehydrates you which makes you perform worse at the gym and creates this negative feedback cycle. Additionally, diet soda's cause you to retain water which will make you look softer and the scale weigh heavier. If the majority of your liquid intake is water, diet soda is just fine. I've been able to lose significant weight while drinking it. It's the carbs that kill you!
