Women don't have to take all of the blame for their body weight, but they do have to bear the full weight of embarrassment when they feel too thin or too fat. Some women work hard to take in enough calories so they don't appear skin-and-bones while others have to count each grape and grain to keep from packing it on; both sides of the metabolism coin toss we're born into and work with through puberty, childbearing and aging.
Being out of shape is more within control, but a majority of women on any given day of any given year will say that they are out of shape and not at their best -- or optimum -- in terms of body image. Mass is just part of this equation, too, because where the weight settles determines which part of the body is embarrassing and covered. Cellulite dimpling the legs and buttocks, saddlebags protruding off of the thighs and hips, and the cute sounding, but so not cute muffin top -- that squishy band of extra fat squishing out of the tops of waistbands -- whether in jeans, skirts or bathing suits, all of them embarrassing to so many women.
All of these weighty issues keep the female body covered and spandexed by day and artfully posed and draped by night.
