Preventing stomach damage

[Zepheryl]

Hello,

My problem is as follows:

I cannot resist following any kind of diet... The only way I can loose
weight is by eating _very_ little. Yet still, by eating very little
(only a few bites of food per day) I heard that I can easily damage my
stomach.

So, what should I do in order to cause minimal damage to my stomach?
For example, I heard it would be a good idea to drink more water... Do
you know anything else that could help me?

Thanks!
