Either go out and buy, or look for a download of Tim Ferriss's The Four Hour Body. It teaches you to lose weight, build muscle, and do tons more things to your body.
It's focused on the Pareto Principle (the 80/20 rule), where 80% of the results come from 20% of the effort.
***UPDATE***
I started by eating one piece of dates, and then drinking a cocktail that consists of cucumber, oranges, apples and ice and then i am only living on raisins and water... i have done an intensive 20 minutes of working out and i feel like a fucked up zombie
