We've all thought it; what is the secret to Jennifer Lopez' incredible, ageless body? The answer? A whole lot of hard work and a pretty strict diet.

Her meals never include processed food.

On top of that, almost everything Lopez eats is organic. A typical lunch might include salmon and a salad that's packed with veggies. Broccoli, peppers, and courgette drizzled with vinaigrette is a favourite, as is kale with crumbled queso blanco and toasted pumpkin seeds. Come dinnertime, she'll switch up the protein — "I like pork and chicken, especially Puerto Rican style" she told UsWeekly — and enjoy it with quinoa or baked sweet potato.

She snacks smartly.

Lopez has a regular show at Planet Hollywood in Vegas, she stars in NBC's police drama Shades of Blue, and she's a judge on the new dance competition show World of Dance, meaning she has to snack smart, but what does she pack? "I always have healthy snacks, like fruits and vegetables, with me," she revealed to People.

Chocolate chips are her weakness.

When Lopez does indulge, it's not with black bean brownies trying to masquerade as the real deal. The singer's new beau, Alex Rodriguez, revealed on The View that her guilty pleasures are chocolate chip ice cream and chocolate chip cookies.

She doesn't stick to just one type of exercise.

When she's in Los Angeles, Lopez works out with Tracy Anderson, who's famous for sculpting the bodies of Gwyneth Paltrow and chef Katie Lee. And in New York, Lopez sees David Kirsch. She loves the fact that they have two completely different approaches — and that's a trick you can pick up even if you're working out solo, in your living room. Kirsch is a fan of planks, push-ups, and boxing, while Anderson says, "we just freestyle." That means lots of small arm weights plus bum and thigh moves that also work her abs.

She never touches these three things.

We all have our vices but Lopez doesn't indulge in any of the usuals. "I don't drink or smoke or have caffeine," she told UsWeekly. On the rare occasion that she does indulge in coffee, it's always decaf.

There's a reason her skin still looks so young.

And it's what your mom has been telling you for years. "I'm rarely in the sun, but if I am, I wear a lot of sunscreen," Lopez told UsWeekly. Keeping her complexion clear is also a big reason Lopez cites for skipping caffeine and alcohol: "That really wrecks your skin as you get older."

She relies on this to beat cravings.

"Protein is my go-to," she told Hello!. "It fills me up and keeps me full longer." A lot of the time it's how Lopez starts her day. She'll whip up a protein shake with whey powder from her Body Lab brand, along with berries, yogurt, and honey.
