Joaquin Phoenix's diet was supervised by a doctor
Joaquin Phoenix's weight loss for his role in the film Joker was extreme and may not have been entirely safe. To achieve the weight loss, Phoenix followed an extremely restrictive diet, which was supervised by a doctor to ensure his health wasn't put at risk. The actor has been open about the challenges he faced during his weight loss journey, including severe physical weakness, emotional stress, and strict dietary restrictions.
Phoenix's weight loss journey for the film began with a consultation with a doctor, who provided medical guidance and oversight to ensure the process was safe. The doctor's supervision was crucial, as Phoenix's diet was extremely restrictive, and it was important to monitor his health and ensure he wasn't at risk of malnutrition or other health issues. The actor's diet consisted of salads with very little dressing, steamed vegetables, and occasionally lettuce, steamed green beans or asparagus, and one apple. This restrictive diet helped Phoenix achieve the drastic weight loss necessary for his role, contributing significantly to his transformative performance in the film.
In an interview with Access Hollywood, Phoenix emphasised the importance of medical guidance when undergoing extreme weight loss. He stated, "It's something I've done before, and you work with a doctor regimented and overseen and safe." This statement highlights Phoenix's recognition of the potential risks associated with extreme weight loss and his commitment to doing it in a safe and supervised manner.
The actor's dedication to his craft and physical transformation for the role of Arthur Fleck in Joker is commendable. However, it is important to remember that Phoenix's weight loss was intended for a specific character portrayal and was done under professional supervision. Extreme weight loss methods, such as those employed by Phoenix, are not recommended for the general public and can have significant health risks. It is always advisable to consult with a healthcare professional before embarking on any drastic dietary changes or weight loss programmes.
While Phoenix's weight loss enhanced his performance and helped him embody the physical and emotional anguish of his character, it also took a toll on his psychology. In an interview on Jimmy Kimmel Live, Phoenix admitted that the process was "difficult" and impacted his mental state, causing him to feel like he was "going mad" due to the lack of food. This experience highlights the potential consequences of extreme weight loss and reinforces the importance of seeking professional guidance and support when undertaking such endeavours.

Phoenix said the weight loss gave him a sense of control
Joaquin Phoenix lost 52 pounds for his role in the movie Joker. Phoenix, a longtime vegan, described the diet as "horrible". He started by eating "super clean"—mostly salads with very little dressing, and steamed vegetables. He also worked out. After reaching a certain weight, he switched to an even more extreme diet of lettuce, steamed green beans or asparagus, and one apple.
Phoenix sought medical guidance to ensure he could lose weight safely. He worked with a doctor who helped him drop weight for his role in The Master, for which he earned an Oscar nomination for Best Actor. The director, Todd Phillips, wanted the character to look "hungry and unhealthy". Phoenix's weight loss was intended for the short amount of time it took to shoot the movie.
Phoenix's weight loss gave him a sense of control and the confidence to dig deep into the Joker's persona. "I felt like I could move my body in ways that I hadn't been able to before," he told the Associated Press. "And I think that really lent itself to some of the physical movement that started to emerge as an important part of the character."
However, Phoenix also experienced some negative side effects from the weight loss. He told Jimmy Kimmel that he became obsessed with food, and that dieting resembled an eating disorder. He also said that the weight loss affected his psychology, making him feel like he was "going mad" from the lack of food.
