I've been eating a healthy diet of protein, more vegetables, and fruits which does seem to have benefits along with staying hydrated by drinking bottled water throughout the day. I avoid drinking soda and fruit juices as I am not wanting the excessive sugars, carbs, or sodium in my system.
To answer your question I have noticed I have lost weight by doing this along with walking or a small amount of cardio, I have lost 4 pounds so far.
