'Nothing tastes as good as skinny feels'

Mild uproar ensued this week after Kate Moss said the statement above in an interview although she continued that it 'You try and remember but it never works.' It seems harsh to me to criticise a woman who has made her fortune through her skinny frame for a comment that is as widely known as 'you can never be too rich or too thin.'
With appearance meaning so much in our society and such value put on being skinny, every mouthful counts. Would it have been better if Kate lied? Most super-skinny women say they eat loads but never seem to gain weight. Is that any more comfort for larger people or will they then be in search for the missing magic thing in their diet that will speed up their metabolism?
In my mind it is better to equate food in as energy out and any over-intake means fat deposits. It's just striking the balance of how important it is in the great scheme of things.
