It looks like Lauren Conrad has everything – but she admits that she has the same insecurities as any other 21-year-old. “Like most girls, I’ve always been self-conscious of my body,” she says.

And now that she’s in die Hollywood spotlight, it’s no surprise that Lauren feels more pressure than ever to look her best.

“When you are constantly being photographed, all your flaws get pointed out. I wanted to get in better shape so I could feel more confident,” she reveals.

So Lauren started dieting and working out with trainer Jarett Del Bene at Equinox fitness in West Hollywood, and it’s working – she’s lost 10 pounds and now weighs 115 pounds.

Fans of The Hills know that Lauren loves her pasta, and she says that bypassing carbs is “really hard.” To break her pasta habit, Lauren keeps nuts, fruit and veggies around when she’s tempted to cheat, although she does allow herself one cheat day a week. Still, dieting can be difficult.

“I have a hard time eating healthy when we travel a lot,” she says. “My friends all make fun of me because when we all get back to my apartment at night, everyone wants to order pizza and I make them eat bean bowls [a high-protein combo of kidney, garbanzo and black beans with tomatoes],” she says.

Luckily, best pal and new roommate Audrina Patridge is on the same diet plan, so the girls keep each other on track. “It’s fun to have a workout buddy!”
