Yet another "Star Trek: Into Darkness" actor has revealed an intense diet regimen that went along with a role in J.J. Abrams' sci-fi flick.

Alice Eve, who plays Dr. Carol Marcus in the film, recently told the UK Telegraph that she radically altered her diet after getting word that she had scored the role. For some five months she made spinach a focus of every meal. 

"You've got to look as if you can hold your own on the Enterprise, and that means you've got to be in proper fighting shape," she said. 

While the diet may sound extreme, it's important to note that Eve probably did not eat only spinach the entire time. The regimen recommends people add two to three cups of spinach to their regular diet, while reducing their intake of fats and processed foods. 

"If you enjoy spinach, then there is a good chance that the spinach diet is a great diet option for you to consider," writes Jodi Morse for Yahoo! "Although many would argue that the spinach diet is just another fad diet, it can really become a lifestyle change, as it encourages you how to incorporate a certain vegetable into your diet on a more frequent basis."

Nutritionally speaking, spinach is a superfood that's low in calories but incredibly dense in protein, vitamin A, vitamin K, folic acid, and carotenoids and flavonoids that protect against heart disease and make muscles stronger.

While Eve used veggies to slim down, "Star Trek" baddie Benedict Cumberbatch went in the opposite direction to bulk up. The 36-year-old says he ate chicken, potatoes and broccoli to fuel, at times, a necessary 4,000 calories a day for workouts. 

"You turn into an absolute creature from hell because all the fuel you’re relying on to get you through the workout disappears … it’s just horrible," he said. 

He added: "Now I know how girls feel. Diets are s***e."
