You can't outrun drinking soda all day.
Soda will also give you a 200+ blood glucose spike within minutes, which isn't really possible with other types of foods. That means it's only a matter of time until you get insulin resistance and then diabetes.
Soda is much more harmful than just some extra calories. There's a reason half of America is pre-diabetic or diabetic and it's not because people don't go to the gym enough or don't work in agriculture anymore.
