how?

"Don't eat bread, chips or crisps..especially. But then all food will be your enemy, so basically - don't eat. Don't drink. Exercise. Run. A lot. Count. Calories that is..religiously. I mean all the time. Gaze. In the mirror and judge yourself, harshly. Don't ever enjoy life and become a boring hungry machine. If you're really dedicated you'll lose your libido, your bum, your breasts - yes even you (and in that case less is not more), stop menstruating, oh did i mention hair thinning? Everything good in your life will be replaced by this obsessive destructive discipline. But don't fret. You'll be rich enough to employ someone to carry your Birkin when you're too weak to do it yourself. Good luck!"
