This morning, we were surprised to learn that beloved Italian designer Valentino Garavani follows a stunningly strict diet–without going too deep into it, the regimen involves “no sugar, no milk, no dairy except goat cheese, no gluten pasta, Bio Rice, no meat, some fish (not the ones with mercury), vegetables, no potatoes, no bread except rice crackers or grissini, one glass of red wine, sugarless sherbet, all sweets made with almond milk and xylitol sweetener, and one coffee a day.” So, basically hell.

Still, we were surprised that designers eat so strict when their bodies aren’t the primary focus of the industry’s scrutiny (well, not as much). This got us thinking: is Valentino unusual? Or extreme? We researched 10 designer diets to determine the answer.
