What does a British socialite and sister to the Duchess of Cambridge eat to drop pounds just days before her wedding?

In less than one month, Pippa Middleton will marry James Matthews, chief executive of Eden Rock Capital Management Group, which has offices in London.

The world has been watching Pippa since 2011 when she walked into Westminster Abbey lifting the train of Kate Middleton’s royal wedding dress. While it was her backside that had us wondering what she ate then, with impending nuptials of her own, we wonder what she may be doing now to get in even better shape — if that’s possible.

Elle reported that Pippa was photographed leaving a fancy fitness center in London, on Wednesday after taking a 75-minute pilates class. Elle also gave details of Pippa’s pre-wedding diet — something most of us have never heard of — The Sirtfood Diet.

The strict diet includes 20 specific foods, rich in polyphenols — micronutrients found in plant foods that apparently boost the body’s metabolism and fat burning mechanisms. Foods such as arugula, red wine, dark chocolate, coffee, kale, walnuts and strawberries are among the acceptable foods.

The Sirtfood Diet has two distinct phases. Phase one, or the first seven days, according to Sirtfood’s site, has you eating only 1,000 calories the first three days, consumed via three Sirtfood-rich green juices and “one full meal rich in Sirtfoods.” The remaining 4 days allow for 1,500 calories broken up between two green juices and two “Sirtfood meals.”

Phase two lasts 14 days and allows three “Sirtfood-rich meals plus one green juice” per day.

But sadly, the Sirtfood Diet can be extremely dangerous and is not recommended by dietitians.

“It’s unhealthy and unsafe to eat below 1,200 calories a day,” registered dietician Brigitte Zeitlin told the Cut. “In addition to not giving yourself the proper energy and nutrients you need each day you’re on this fad diet, eventually you’re going to go off of it. You’re going to gain all of the weight you lost back, and more often than not, you’re going to gain even more weight back.”

The Sirtfood diet is just another fad, so if you’re thinking about doing a diet of your own soon — and who isn’t well aware that summer is just days away — consider upping your intake of healthy foods like spinach, carrots and other fruits and vegetables. Stay away from yo-yo dieting which has been shown to be bad for your heart and can cause stress on your body.

“Extreme diets like this don’t work,” Zeitlin said. “Most brides usually burn out on them, and they get incredibly cranky because they’re starving themselves. At a time when you’re already incredibly stressed out, the last thing you need to do is add in the stressful factor of not eating properly.”

No perfect backside is worth risking your health and happiness.
