28-year old Brooke lost over 170 pounds in 4 & 1/2 years via healthy eating and exercise!  Go on, girl.

However she said "Shape" magazine rained on her parade when she submitted a "before and after" pic for their SUCCESS STORIES column... but they shot her down.

They told her to submit a different pic, one with a shirt on because it's "policy" (not true, I have seen many pics of people in bikinis/sports bras etc... I read this magazine religiously).

What do you think?  This is Brooke's after pic, you can see her before HERE
