This question already has an answer here:
I'm 25 years old (soon will be 26), height 174cm and weight is 77KGs. After reading some questions here I realized that in order to achieve my dream body shape (link) I need to lose as much fat as I can. My questions are:
1- How much fat I should lose?
2- It seems there is a difference between fat and weight, so how can I measure how much fat I have now?!
