Good morning! Try this, stand on your left foot and set your right toe down. Press with your right toe so that the muscles in your right leg are tense. Now poke at it. You will feel firm muscle ... anything soft-ish is fat. You already know how to get rid of fat ... the rest is slender shapely healthy sexy muscle that you can build into awesome looking legs!
Eat good food. Move yourself. Lift something.
You'll be surprised how much you don't miss grain.
