Lauren Conrad and Whole Foods

How does “The Hills” star Lauren Conrad stay so slim? One of her secrets is the food she buys. Laguna Beach alum LC was recently spotted at Whole Foods Market in Los Angeles, making her weekly grocery pickup.

Growing up, Lauren was constantly athletic and active, maintaining a trim physique on her 5’6 frame. In recent years, however, her physical activity level slowed as she became more involved in pursuits of a career in fashion design and reality television endeavors and endorsements.

Determined to make her body a priority, Conrad turned to trainer Jarrett Del Bene, who created a customized plan for LC and her aspiring-“mactress” roommate, Audrina Partridge.

The plan consists of 1500 calories per day, distributed across six meals. Staples of the diet include salads, high-fiber cereal, low-fat yogurt, nuts, and healthful proteins such as tilapia and chicken. Workouts include hiking, running on the treadmill, and lifting weights for 45-60 minute sessions. It’s been over a year since LC’s adopted the new plan and healthy shopping habits, and it’s definitely working out for her!
