If your first name is Jessica and you're a smoking hot actress, apparently the name of the fitness game is CrossFit. Add in a low-carb diet, especially a Paleo-style one, and you've got the recipe for a perfect bikini body. Exemplifying the benefits of CrossFit plus a low-carb diet is Jessica Alba, reported Voxxi News.

The CrossFit program that she uses is often paired with a Paleo low carb diet. One of the hottest new Paleo-style low-carb diets in Hollywood is the Bulletproof Diet: Click here for details on the book that explains how to use it for weight loss and health.

Her trainer Jennifer Johnson complimented Alba's diet dedication. "That’s Jessica’s strong point: She’s motivated nutritionally, and she eats a balanced diet of salads and proteins," revealed the trainer. "If you’re eating right, that’s more than half the battle."

Jessica Biel follows the Paleo diet as well. Get the skinny on the best Paleo diet books and cookbooks by clicking here.

"There is so much pressure to look a certain way in this town. But it's nice to have a little meat on you, and I hope I inspire women to appreciate their muscular calves!" Biel told Shape magazine. "I’m comfortable with my body and who I am because I work out a lot!"

Not every health expert is dubious about the benefits of the Paleo diet. Dr. Mehmet Oz recently featured the plan on his talk show and noted that you can lose up to 75 pounds in six months by customizing the diet so it works for you.

One advantage of the diet: It contains a significant percentage of protein. And that's the key to cutting cravings for carbohydrates according to a new study, reported the Winchester Daily Monitor on July 9.

Both Biel and Alba get a boost in staying so slim by choosing the Paleo way. Researchers at the University of Sydney found that by following a low carb diet with sufficient protein, your appetite will be suppressed, making it effortless to eat less.

Commenting on the results of the study, Professor Raubenheimer noted, "We can use this information to help manage and prevent obesity, through ensuring that the diets we eat have a sufficient level of protein to satisfy our appetite." He also disclosed that the percentage of protein in the diet has decreased during the past six decades.
