Ok i'm really sorry but who on earth told you that being a skeleton is beautiful?
Unless you are below 4 ft in height i really think you are making a big mistake..and i'm not even talking about health reasons...
I don't know how old or tall you are but presuming you are out of playschool 30 kilo's is a stupid weight to want to weigh...but i suppose each to their own i'll be curious to see how long you can keep yourself up and going without all the side effects of basicly starving yourself...maybe a holiday to Africa should do the trick...go and visit a clinic there...see all the hollow faces and bloated bellie..i'm sure that will make you happy..as you're heading yourself that way.
Or visit a clinic talk to some1 dying because they took their diet too far..and there is no way back coz their bodies have shut down lots of vital organs...maybe before you start distroying them you can donate them to someone who does appriciate them...have a look on a transplant list and see all the people who would give anything for a liver or kidney...the ones that you are about to distroy...Well done and good luck on your journey!
