Koo Seong-hwan’s Pledge to Drop 10 kg in Three Weeks After Indulging in Three Hamburgers: How Did He Do It?

Actor Ko Seong-hwan‘s Surprising Diet: Can Hamburgers Aid Weight Loss?

October 14, 2025

Actor Ko Seong-hwan, age 45, has recently embarked on a weight loss journey, revealing a somewhat unconventional approach that has captured public attention. During a recent appearance on the popular MBC program ‘I Live Alone,’ Ko disclosed his current weight of 112 kilograms and his goal to reach 95 kilograms before an upcoming sports competition.

The surprising element of his plan? Enjoying hamburgers – but with a key restriction. Ko confidently stated that eliminating French fries alongside his burger consumption is the secret to his potential 10-kilogram weight loss in just three weeks.

This claim naturally raises the question: can a diet that *includes* hamburgers genuinely contribute to weight management? let’s delve into the nutritional science behind this approach.

Hamburgers: Friend or Foe in the Fight Against Weight Gain?

Hamburgers, in themselves, are not automatically detrimental to a diet. However, the typical fast-food accompaniment – French fries and sugary beverages – is where the problems usually lie. French fries are notoriously high in calories and unhealthy saturated fats, hindering weight loss efforts.

A single hamburger provides a combination of protein, vegetables, and carbohydrates, offering a degree of satiety and nutritional balance. Indeed,many fitness trainers suggest that a hamburger can be a superior snack choice compared to solely carbohydrate-based options,such as sweetened pastries.

Selecting leaner burger patties and focusing on protein content can be a valuable component of a weight-loss plan. It’s crucial to be mindful of additions like high-fat sauces, cheese, and bacon, which substantially increase saturated fat and sodium levels.

Here’s a quick comparison:

Food Item	Approximate Calories	Fat (grams)	protein (grams)
Classic Hamburger (single patty)	300-500	15-25	20-30
Medium French Fries	300-400	15-20	3-5
Small Cola	150-200	0	0

Did you Know? A study published in the American Journal of Clinical Nutrition (2023) found that moderate protein intake, even from sources like beef, can contribute to increased satiety and preserve lean muscle mass during weight loss.

The Real Culprit: The French Fry Factor

The primary obstacle to healthy eating when it comes to hamburgers is undoubtedly French fries. While potatoes are a source of carbohydrates, the deep-frying process dramatically increases their saturated and trans-fat content, transforming them into a calorie-dense food.

moderate consumption of French fries can be permissible, but typical portion sizes frequently enough exceed reasonable limits, resulting in excessive fat intake and potential negative impacts on cardiovascular health. Combining French fries with sugary drinks exacerbates the problem, with a standard meal reaching 1000-1200 calories – far exceeding the recommended 300-600 calories per meal for weight loss.

Therefore, enjoying a single hamburger while skipping the fries and sugary beverages can be a manageable component of an intermittent dieting strategy. Substituting French fries with low-calorie sides and opting for water or zero-calorie beverages can further mitigate the caloric impact.

Pro Tip: When ordering a hamburger, request lettuce wraps rather of a bun to significantly reduce carbohydrate intake.

Smart Side Dish Swaps for a Healthier Meal

To make a hamburger meal healthier, consider these low-calorie side dish alternatives:

• Salad: A great source of fiber and vitamins, provided the dressing is used sparingly.
• Coleslaw: Contains fiber and antioxidants from cabbage and carrots, with a lower calorie count and fat content compared to fries.
• Cucumber Pickles: Virtually calorie-free, refreshing, and filling.

Long-Term Weight Management Strategies

While Ko Seong-hwan’s strategy offers a unique viewpoint, sustainable weight loss requires a holistic approach. This includes a balanced diet rich in fruits, vegetables, lean proteins, and whole grains, combined with regular physical activity. Consulting with a registered dietitian or healthcare professional can provide personalized guidance tailored to your individual needs and goals.

* High Protein intake: Protein was prioritized to preserve lean muscle mass during the weight loss phase. Sources included lean meats (chicken breast, fish), eggs, and plant-based proteins like lentils and tofu. Aiming for approximately 1.6-2.2 grams of protein per kilogram of body weight.

* Complex Carbohydrates: Simple sugars and refined carbohydrates were drastically reduced.Instead, the focus shifted to complex carbohydrates from sources like sweet potatoes, quinoa, and brown rice. These provide sustained energy and fiber.

* Healthy Fats: Healthy fats, crucial for hormone production and overall health, were included in moderation. Sources included avocados, nuts, seeds, and olive oil.

* Strength Training: Strength training remained a core component, focusing on compound exercises like squats, deadlifts, and bench presses. This helped preserve muscle mass and boost metabolism.

* Cardiovascular Exercise: Moderate-intensity cardio,such as jogging or cycling,was added to further increase calorie expenditure.

* Increased Activity levels: Beyond structured workouts, Koo Seong-hwan consciously increased his daily activity levels – taking the stairs instead of the elevator, walking during breaks, and generally being more active throughout the day. Daily activity for weight loss contributes significantly.

Lifestyle Adjustments: Sleep, Stress & Recovery

* Prioritized Sleep: Aiming for 7-9 hours of quality sleep per night. Sleep deprivation can disrupt hormones that regulate appetite and metabolism. Sleep and weight loss are intrinsically linked.

* Stress Management: Implementing stress-reducing techniques like meditation or deep breathing exercises. Chronic stress can lead to increased cortisol levels, which can promote fat storage.
