I'm not hungry, but I havn't really eaten anything except..?

yes, its terrible. All diet are bad. You got to eat healthy and live healthy by eating real quality food and exercise. Although what you are eating may be healthy, like apple, carrot... etc. Ginger Ale is still considered to be junk food no matter if it's diet or not. the nutrients that you are consuming is not balance, which may cause deficiency, so I personally wouldn't suggest any kind of diet to anyone.
