REVEALED! 2015 Has she gone too far in her quest for bridal perfection?

Like many brides ahead of their big day, and with the countdown to her royaltystudded wedding in full swing, the Duchess of Cambridge’s sister, Pippa Middleton, is well and truly in “shedding for the wedding” mode.

The 33-year-old, who is set to exchange vows with millionaire stockbroker James Matthews next week, is reportedly following a rigorous pre-wedding diet and workout regimen to ensure she’s at her bridal best.

But new pictures of Pippa looking thinner than ever in London last week have royal watchers worried she may have overstepped the mark.

Not only has her once-athletic figure been replaced by a narrow frame, but the pert derriere that caught the world’s attention at her sister Kate’s wedding in 2011 is now significantly smaller.

Pippa is reportedly following the strict Sirtfood Diet, which involves a drastically restricted kilojoule intake and eating “sirtfoods” such as celery, strawberries and walnuts, which are rich in polyphenols and said to enhance the body’s ability to burn fat.

Over the first three days, proponents consume just 4000kj, in the form of three green juices and one meal rich in sirtfoods. During the next four days, they can increase their intake to 6200kj (two green juices and two meals). Then follows a final 14 days of sirtfoods plus a green juice each day.

Pippa’s adherence to a strict diet is somewhat out of character. The keen marathon runner, who has also upped her Pilates and gym sessions in recent weeks, has said before she is only y strict aboutout her food intake before a race.

“I don’t get fussy… because I enjoy food too much,” she said. “But a week or so before an event I’m quite conscious of eating really nutritious foods to store energy, and I cut out alcohol, refined sugar and processed foods. foods.”
