Everything is possible my friends! I want to you think for a second about what the deciding factors behind a persons body fat percentage are. Can you tell me? Is it luck?! LOL, certainly not! Is it extreme discipline, Nope. Is there any rule that says "you must eat disgusting health food if you want to be lean" ?? Of course not! that's crazy talk. 
Getting lean is all about fueling your body with the Earths amazing nutrients (real food), stay away from over-processed junk, and train like an athlete (try to improve every day, don't just go thru the motions). Oh! and the most important detail of all: believe in yourself. Stop thinking about being overweight or about food making you fat. Food does not make you fat, only your negative thoughts and self-sabotaging behavior can do that to you. When you are full, stop eating. When you are hungry, eat. Food should be thought of as fuel to give you energy, pleasure and delight, not as treat or punishment. Oh and yes, food is supposed to be delicious. So if you are eating tasteless boring gross food just in the hopes of getting leaner, quit that. It's no way to live. Eat well and be well.
