A real personal question about weight and stuff. need help !?

alrighty then .. to begin with i am a short girl about 5'1 . i have a gut + love handles ! it really takes a toll on my life. the thing i don't understand is that loosing weight doesn't help. im 109 and everyone always calls me skinny and flat and all that,i can fit in size 0 jeans ! (sometimes) but im mostly a 3 yet it still fits me big. whenever i tell someone im fat they laugh cause i hide my gut with jackets or big shirts. i don't wanna loose weight im way to skinny so how can i get rid of this damn gut and love handles without being anorexic or something .. :(
