The French magazine Grazia is reportedly promoting a diet in which you pretend to eat while those around you think that you're participating in their foodie ways--you're not supposed to actually ingest anything. Supposedly, the diet was inspired by a Dolce & Gabbana ad campaign in which Madonna only pretended to eat.
The magazine features a recipe for 'la soupe à l’eau' or 'water soup.' Rumor has it that it's okay to add salt.
Dieters are encouraged to binge on oxygen at oxygen bars, which is good since going without food is dangerous, but going without breathing is even more quickly fatal.
