Hello Brokenwing
What do you mean when you say "pure" and "impure" ?
And as much of a hypocrite as I may be, It's not good to lose weight fast, if you are overweight, then the best way is too eat healthy and exercise but not excessively.
And it will take time, I know we as humans want things fast fast fast. And as annoying as this is, I have to ask if you have anyone irl that you talk to about you food issues, or any issues for that matter.
