First up, I'll stick my hand up for a greater appreciation of our individual bodies, and as a collective. There are far too many trashy mags these days with "she's too fat" and "she's too skinny" on the covers, misleading females everywhere as to what's even healthy these days.
Having said that, even when we do have a gorgeous acceptance and love of our body, there are times when we may have let our healthy eating habits slide, work and study has taken over our lives, illness has been present, or something else that may have led a few kg's to creep on up, and for whatever reason now, you might be struggling to knock em back off.
