When you say natural weight loss solution, do you mean pills, potions or lotions? If so, I know of none and I can't think of a faster way to seperate you from your money.
However, if you mean things that "help" you with your weight loss goals, well then yes absolutely.
I cover most if not all of the weight loss aid natural supplements in the supplement index of my e-book.
If you're really interested in losing weight as fast as possible while keeping it off, I explain why and how my weight loss program works in my new weight loss and diet program.
