3. Carbonated water instead of soda  

If you are addicted to sodas, then stopping drinking them will be a very challenging task. Nevertheless, you can try and reduce the amount of soda you consume daily by replacing at least one can of soda with a bottle of carbonated water. This is how you can easily reduce the amount of calories you consume by 150. If plain water tastes boring, try and add a bit of fruit or some sweetener. And do not try to cheat and compensate for your soda elsewhere!
