Actress Goo Hye Sun has become a topic of discussion following her recent expedition to the Himalayas, where she experienced an unexpected 8kg weight gain. The star shared details about this ‘bulking period’ on her social media, sparking considerable interest.
Himalayan Expedition and Unexpected Weight Gain
On March 18th, Goo Hye Sun posted a short video clip accompanied by the caption, “Himalayas 8kg bulking period.” The video was filmed at an altitude of 4,300 meters (approximately 14,100 feet) and was shared as a preview for her appearance on the MBN program ‘Kim Ju-ha’s Day & Night,’ scheduled to air that evening at 9:40 PM. In the program, Goo Hye Sun detailed her journey and the subsequent physical changes.
The actress successfully summited a peak in the Himalayas, reaching her target altitude of 4,300 meters. She described the demanding nature of the trek, stating, “I walked for 16 hours a day.” This accomplishment alone garnered attention, but the most striking revelation was her physical condition upon returning to lower altitudes.
Contrary to the common expectation that prolonged stays at high altitudes and strenuous trekking would lead to weight loss, Goo Hye Sun revealed a surprising outcome. After returning to Korea, she discovered she had gained 8 kilograms (approximately 17.6 pounds) while recovering in the hospital. This unexpected result became a focal point of her discussion.
Reasons Behind the ‘Bulking Period’
When asked about the cause of this significant weight increase, Goo Hye Sun offered a candid explanation. She explained that the extreme conditions necessitated a different approach to nutrition. “If I didn’t eat, I couldn’t go on,” she stated, reflecting on the circumstances. She admitted to consuming everything available, saying, “I ate all the rice there.” This included food typically given to horses, as well as cookies and hard candy, which she consumed to meet her energy needs. Her frank confession amused the program’s production crew.
The harsh Himalayan environment made strict dietary control nearly impossible. To sustain herself and maintain energy levels during the arduous trek, she had no choice but to eat whatever was accessible. High-altitude environments are known for their low oxygen levels, which can significantly increase metabolic rate and energy expenditure. Sustained trekking, especially for 16 hours a day as Goo Hye Sun experienced, requires a substantial caloric intake to compensate for the increased energy demands and prevent severe fatigue.
The Physiology of High-Altitude Trekking
At high altitudes, the atmospheric pressure is lower, meaning less oxygen is available in each breath. The body must work harder to deliver oxygen to tissues, leading to increased heart rate and respiration. This physiological stress, combined with the physical exertion of trekking, burns a considerable number of calories. Furthermore, the body’s response to altitude can sometimes include increased appetite as it tries to compensate for the energy deficit. Goo Hye Sun’s experience highlights how essential adequate nutrition is for survival and performance in such extreme conditions, even if it leads to temporary weight gain upon return.
Goo Hye Sun’s Diverse Career and Pursuits
Beyond her acting career, Goo Hye Sun has consistently pursued diverse interests and challenges. She entered Sungkyunkwan University in 2011 to study film, demonstrating her academic ambitions. She later pursued graduate studies in science journalism at the Korea Advanced Institute of Science and Technology (KAIST), earning a master’s degree.
Throughout her career, Goo Hye Sun has been active in various fields, including acting, film directing, visual arts, and music. Her academic achievements further broaden her profile, showcasing a commitment to continuous learning and expanding her expertise. Her recent successful Himalayan expedition adds another significant accomplishment to her multifaceted life, once again capturing public attention.
