How To Get From Ideal To Lean

Sssssssssssh, this is a subject that one doesnt like to speak out loud. So I am going to whisper. At long last I no longer wants to be in denial. So I bought the Accu-Measure Fitness 2000, its a Personal Body Fat Tester. I just need to find out for sure how much is my body fat percentage. The manual asked me to pinch a flab on my stomach, yes yes and yes I have to admit that after all the diet I still have flabby abs, then use the clipper to measure the thickness of the flab. Anyway, mine reads 12mm, and for my age range it means my body fat is 16.8%. So what does it mean? Is it good or bad? The figure falls under column IDEAL! Hooray, I have an ideal body fat! But then my mission is to be catagorised as LEAN. So how do I go from Ideal to Lean? It seems I have to reduce my body fat by 5%! Small figure eh? Yea rite, only at this very moment I am thawing my frozen lamb chop because I've been craving for it. Aaaaaaaaaaah worst come to worst I still have an ideal body fat. Thats a good thing right?
