Alas, as a fellow pear-shape, I agree with the other posters: there's no way to diet or exercise your way to overcoming your body's preferences for where it stores fat. I've so wished I could just move my butt fat to my boobs, but it just doesn't work that way! I lose noticeable weight first from my waist, then boobs, then FINALLY butt/thighs.
Despite ending up with smaller boobs, I'm far happier with my small bottom half than I was when both my butt and boobs were bigger!
Zone diet on and off for several years....worked, but too much focus on exact meal composition
Primal since July 2010...skinniest I've ever been and the least stressed about food
