Pippa Middleton's diet secrets are not so secret anymore!
The 30-year-old recently participated in the Bosphorus Cross Continental Swimming Race in Istanbul and revealed to Hello! magazine what kind of healthy eating habits she followed to get in tip-top shape for big athletic event.
Pippa explained that "wholesome carbs," like quinoa, brown rice and lentils, were essential for preparing for the race. "To maintain energy I try to eat more protein, particularly fish or chicken," Kate's sis said. "A lot of people swear by carb-loading in the run-up to an event but it doesn't really work for me, so I just up my protein intake."
