Actor Sung Dong-il is catching eyes with his noticeably slimmer figure.
On the 4th, the Disney+ original series ‘Bloody Flower’ was released. In this drama, Sung Dong-il plays the role of lawyer Park Han-jun, who must save a murderer to save his sick daughter.
With outstanding acting skills in every project, actor Sung Dong-il provides viewers with a high level of immersion. He revealed at a previous drama press conference that he lost over 10kg to portray a desperate father.
The Secret to His Diet is ‘Walking’ and ‘Running’... Be Careful with Knees in Middle Age
Sung Dong-il mentioned walking and running as his management methods on actress Hyeri's YouTube channel. He stated, “I switched from running to walking because my knee cartilage isn’t good,” adding, “I usually walk about 14km.” By developing this exercise habit, he lost about 10kg in two months.
Walking is a low-intensity aerobic exercise that can be done for a long time. Especially, walking after meals is very beneficial for stabilizing blood sugar levels. When blood sugar rises sharply, our body secretes a lot of insulin, leading to a tendency to store fat.
The calorie expenditure is also significant. A person weighing 60kg who walks 14km like Sung Dong-il burns about 700kcal. Approximately 50kcal is used per kilometer. Aerobic exercises that burn a lot of calories, like walking, are effective in eliminating belly fat. Moreover, they place less burden on joints and knees, making them relatively safe for beginners and middle-aged individuals.
For walking, a speed of 5-6km is recommended. It’s good to adjust the speed so that you can breathe a little harder but still have a conversation. However, keep in mind that walking is not directly burning belly fat but rather preventing it from accumulating.
Actors Who Rapidly Lose or Gain Weight for Their Roles... Importance of Health Management
Like Sung Dong-il, many actors manage their weight to perfectly portray their characters. Weight management tailored to the character enhances viewer immersion. However, it can negatively impact the health of the actors.
Rapid weight loss can lead to nutritional deficiencies, skin troubles, decreased physical strength, metabolic slowdown due to muscle loss, and hormonal imbalances. Especially, those who repeatedly lose and gain weight are at a significantly higher risk of metabolic diseases and cardiovascular diseases.
In fact, Hollywood actor Christian Bale lost over 30kg for the movie ‘The Machinist’ and then gained weight in a short period for ‘Batman Begins’. He once lamented, “It felt like my mind had left my body.”
If there are significant changes in weight over a short period, it’s important to quickly restore the body’s balance and function to avoid health issues. If you have lost too much weight in a short time, you should adequately replenish protein, vitamin B complex, iron, calcium, and zinc to resolve nutritional imbalance issues. A weight loss of 0.5-1kg per week is appropriate.
