With her almost-royal wedding to hot financier James Matthews coming up this month, Pippa Middleton has, like any bride would, been putting her diet and exercise regime into overdrive. As the First Sister of England, she certainly has appearances to uphold. Besides hour-long Pilates classes at an exclusive London gym, Miss Middleton has been sticking to an interesting - and highly restrictive - diet plan. Dubbed the Sirtfood Diet, it encourages meals high in polyphenols, micronutrients found in plant foods, which apparently rev up one's "skinny genes." Whatever that means. 

While green juices and caloric cutting are required, most of the "safe" foods on the plan aren't so bad. Chocolate and red wine? Count us in.
