Recently, actor Lee Sung-min has been drawing attention with his dramatically changed appearance after losing 10kg. At 57, Lee Sung-min showcased a sharper jawline and a slimmer physique in a pictorial video for the fashion magazine Dazed Korea, garnering significant interest from netizens. While he made a strong impression in the Netflix series 'The King of Prison' as the Minister of Education, many have commented that his recent look appears gaunt.

What are Lee Sung-min's Diet Secrets?

Lee Sung-min revealed on the YouTube channel 'Un Dden Un' in the segment 'Pinggyego' that he lost 10kg for the filming of the movie 'Ode to My Father 2'. In past interviews, he shared that he managed his weight by reducing carbohydrates and sweets, eating only one to two meals a day, limiting late-night snacks, and exercising concurrently. So, why were his weight loss methods so effective?

Reducing Carbohydrates and Sweets

Reducing carbohydrates and sweets, as practiced by Lee Sung-min, greatly helps in reducing calorie intake. Refined carbohydrates and sugary foods are digested quickly and cause blood sugar to spike rapidly, leading to increased insulin secretion. This creates an environment where energy is easily stored as fat. Therefore, by reducing sweets and refined carbs:

• Unnecessary snacking decreases.
• Total daily intake naturally reduces.
• Fat loss effects can be expected.

However, carbohydrates themselves are not inherently bad. They are an essential energy source for our bodies, so it's important to consume quality carbohydrates in moderation. For instance, it's better to opt for brown rice, sweet potatoes, or oats instead of snacks or sugary drinks.

One to Two Meals a Day and Limiting Late-Night Snacks

Lee Sung-min's practice of eating 1-2 meals a day and limiting late-night snacks is similar to the recently popular concept of time-restricted eating. The reason this method is effective for weight loss is simple: by reducing the eating window, overall daily intake naturally decreases. It's especially beneficial to cut down on late-night eating, as it can add unnecessary calories.

However, what's more important than the number of meals is consuming sufficient nutrients. Eating enough protein, vegetables, and healthy fats allows for a balanced diet.

Points to Note for Middle-Aged Dieters

When individuals in middle age lose a significant amount of weight, they often hear comments about looking older. While rapid weight loss in a short period can lead to a sharper jawline and slimmer body, it can also make the face appear more gaunt and aged due to the loss of water and muscle mass. After the age of 50, strategies to preserve muscle are more crucial than weight loss itself. A decrease in muscle mass lowers basal metabolic rate and reduces energy expenditure, making weight management more challenging.

Therefore, the formula for healthy dieting in middle age and beyond is simple: 'Weight Loss = Fat Loss + Muscle Maintenance'. To achieve this:

• Ensure adequate protein intake.
• Incorporate strength training.
• Consume quality carbohydrates.
• Reduce late-night snacks and sugar intake.
• Avoid rapid weight loss.

Lee Sung-min's health management methods are simple yet contain effective principles. These are easy-to-follow strategies for anyone, so why not try a healthy diet yourself!
