Power Ranger read also this. i will recommend to drink water rather than sodas whether it is diet or not. u gain more weight with diet soda.look below

why is diet soda bad?

1. Sodas bad for your teeth - although diet sodas contain far less sugar than regular sodas and are mostly made up of artificial sweeteners, they're still highly acidic and may damage your teeth in the long run.

2. Diet soda can make you gain weight - even though diet drinks contain less calories than the original beverage, it that they're really that good. They might still be rich in calories. In addition, there's nothing like sweetened drinks to help you develop a craving for other sweet food, which means more calories.

3. Drinking diet sodas makes you drink less of more healthy beverages like water, green tea, or natural juices. You're missing out on the good things and sticking to the bad.

4. Drinking unhealthy drinks often makes you crave to snack. I often see people who drink bad stuff munch away on pretzels or other quick snacks which just stuff them with calories.

5. Aspartame, which is the sweetener which is often used to flavor diet sodas is the subject of much debate. There is research that links it to tumors in animals. It is currently deemed safe by the FDA, but there are numerous side effects concerning this chemical.
