I deplore hollywood actresses and models that look like starving african children. When I see them walking (on tv or pictures) it's almost like a sack of bones rattling. If i have daughters they'll be raised to know that it's not about being skinny, it's about being healthy if you're 40+lbs over or underweight you're not healthy.
That could be too general a standard. Surely a person of normal weight who either has a fantastic metabolism or eats small amount of bad food is not as healthy as a person who is underweight or overweight but eating a nutritious diet. I have know painfully thin vegetarians as well as obese vegetarians; they both eat a better diet than someone who consumes 2000 calories a day of hamburgers or beer and weighs ok for metlife.
