Pom Klementieff had to undergo a major transformation in order to portray the empath Mantis in the MCU and it wasn't just a physical one. Her character has such a unique background and power-set that Klementieff had to go through some serious mental effort to become the adorable alien we know and love.
Actors who portray superheroes tend to have some pretty strict dietary rules in order to achieve the impressive physique they need that is even more apparent when you factor in the ridiculous body standards that celebrity women must deal with. But Klementieff's diet is not as strict as you might think she just changes it to suit her needs for whatever role she is currently playing.
In an interview with Byrdie, Klementieff discussed her upbringing and how her diet changes depending on the current role she is playing.
Pom Klementieff's first major Hollywood role was in Spike Lee's remake of Oldboy. She told Filler that she actually came prepared to show off her fighting skills during the audition for that film, and that she enjoyed her boxing and Tae Kwon Do training so much that she continued after filming wrapped. It's easy to assume that may have had something to do with her getting cast in the action-heavy world of the Marvel Cinematic Universe.
Superhero Jacked writes that Klementieff does almost no "traditional" workouts it's all practical stunt and fight training. This also helps prepare her for the rigors of long shooting days.
