Jake Gyllenhaal Weight Loss Story - An Overview


Gyllenhaal has been critically acclaimed for his roles as Homer Hickam (October Sky, 1999), Jack Twist (Brokeback Mountain, 2005), Morf Vandewalt (Velvet Buzzsaw, 2019), Edward Sheffield (Nocturnal Animals, 2016), and of course, Donnie (Donnie Darko, 2001). When it comes to work, Jake Gyllenhaal is known to be utterly dedicated towards and immersed into any project that he takes up. 


The actor wowed fans with his transformation for the movie Nightcrawler, playing a part for which he had to lose 30 pounds. Jake Gyllenhaal weight loss is an ever-trending and inspiring story among countless celebrity weight loss journeys that people are still profoundly fond of.


The 2014 Halloween release featured Gyllenhaal as Lou Bloom, a psychotic journalist who prowls the night trying to capture disturbing crime footage to sell to local news outlets. Lou Bloom is a figuratively diisturbed and disoriented character and would not fit the physical description of a buffed up and bulky man, which Gyllenhaal himself was. So the Oscar-nominated actor went all in and got into a strict diet regimen that would go down in the history of celeb weight loss stories.

Jake Gyllenhaal weight loss is all about how he went to the absolute extreme to get himself in Lou Bloom’s shape. When we read celeb weight loss stories, we usually look at how celebrities switch to new planned out regimens. But that is not what Jake Gyllenhaal did for The Nightcrawler. He cut his staples down to kale salads and chewing gum. The actor would keep a bowl of luxury chewing gum with multiple flavours to trick his brain into thinking that he was having more food than he actually was. He would then have a cup of almond tea that transferred no more than one calorie. He also went on a 15-mile run every night to catalyse the weight-loss process.

In an interview with Entertainment Weekly, Gyllenhaal described the choices he had to make in order to meet his own expectations of Lou Bloom’s physical imagery.


The running thing, you’re pretty hungry because you’re not eating a lot of food. You’re lonely because you’re not meeting your friends for dinner. People go, 'Hey you want to meet for dinner after work?’ I go, ‘Well, I’m shooting all night.’ ‘Alright, you want to meet for lunch?’ I’m like, ‘I can’t!’ So I’m gonna go run.


The ‘Nightcrawler’ also stated that a lot went into keeping himself awake, alive, physically functioning and active enough to shoot the movie while he put his body through tons of stress to fit the role perfectly.

When asked about Jake Gyllenhaal weight loss struggles, the actor revealed that he would try to cut down his calories to the absolute bare minimum. However,losing 30 pounds from his 180 pound frame was just not just about transitioning physically into Lou. He stated that his vigorous weight loss methods helped him in psychologically delving into his character. Lou, a sociopath, was always ‘figuratively hungry’. Jake said that


I knew if I was hungry that I was in the right spot.


Jake told the media at an event during the promotion of the film. He also talked about how the chemical and mental effect of the process was a ‘struggle’ but also ‘fascinating’.

At a certain point during the shooting of the film, Jake almost stopped eating altogether. When the hunger pangs got a little too much, he would try to make do with small bites of meat, crackers, or his usual kale salad. The actor ran 15 miles from his house to the sets of the film every night. Despite the unpleasant physical aftermaths of the process, co-stars and crew remember him trying his best to maintain his demeanour during shoots. If he snapped, he would apologise immediately after, saying that he was grumpy because he had not eaten. He was usually aware of his surroundings and actions and tried to put on his best self and give his best performance, all at once.

Jake Gyllenhaal weight loss regimen was not one with a proper diet plan or a list of things he allowed himself to do. The on-screen Lou Bloom simply cut down to the least that he could eat. Jake put his body on survival mode and only allowed as much intake as it would  take to keep him alive. Having done that, he further took on the physical and mental strain of the shooting added with physical activity to distract himself while he was transitioning into Lou. 


The most remarkable part of Jake Gyllenhaal weight loss is the fact that the actor kept himself calm and composed throughout the shooting and nailed his part as the character while undergoing the chemical imbalances of his newfound diet plan.
