Actor Park Hae-jin (42) chose a diet for his 'body' rather than for 'taste'.
Park Hae-jin appeared as a guest on tvN's 'Health Farmer' broadcast on the 11th, showcasing his amazing self-management.
Starting from the morning, Park Hae-jin flaunted his muscles while running 10.5km. Standing at 185cm tall and weighing "79kg these days," Park Hae-jin has built a solid body without excess fat through running and gym workouts. His six-pack abs were clearly visible.
His diet management was even more rigorous. When asked about his breakfast, Park Hae-jin replied, "I eat the same thing every day," saying, "Olive oil, lemon juice, salad, one chicken breast, Greek yogurt, and a little fruit."
When Choo Sung-hoon asked, "Isn't it boring to eat the same thing every day? You should eat what you want to be happy," Park Hae-jin jokingly retorted, "Do you eat for fun, brother?" revealing his strict diet management.
Park Hae-jin, the 'self-management king,' consumes energy, improves cardiovascular fitness, and maintains his condition through fasting runs, followed by a breakfast centered on satiety, nutritional density, and good protein. Let's take a look at how he achieves this balance.

Benefits of Running for Dieting and Management
Running is expected to remain a popular exercise in 2026. Since the beginning of the year, many celebrities have continued to run even in the winter cold.
To lose weight, the calories consumed must exceed the calories ingested, and regular physical activity is essential to maintain the lost weight. Running is a representative high-intensity aerobic exercise that is relatively easy to secure exercise volume over time. Running at moderate intensity for more than 20 minutes promotes energy consumption and burns body fat, which can greatly aid in dieting. A total of 150 minutes of moderate-intensity or 75 minutes of high-intensity running per week is recommended. Consistent running has various benefits, including improved cardiovascular function, stress relief, and better sleep.
If you are a beginner who started running in the new year, it is advisable to start with an interval of 'walking + light jogging' and gradually increase the distance and time each week. In winter, special attention should be paid to stretching before and after running to prevent injuries.

Reasons Why 'Olive Oil, Lemon Juice, Salad, Chicken Breast, Greek Yogurt, and Fruit' Are Good for Breakfast
Park Hae-jin stated that he has breakfast every morning with a combination of foods that are good for the body. His meal, consisting of olive oil, lemon juice, salad, chicken breast, Greek yogurt, and fruit, provides a high-protein, low-calorie combination that promotes satiety and helps stabilize blood sugar and manage weight. This diet enhances gut health and antioxidant effects, benefiting overall well-being and dieting.
Olive oil and lemon juice promote liver detoxification and bile secretion, while unsaturated fatty acids improve cardiovascular health. The probiotics in Greek yogurt and the dietary fiber in salad and fruit increase beneficial gut bacteria, aiding digestion and relieving constipation. Chicken breast and fruit provide protein and vitamin C, contributing to muscle maintenance and anti-aging.
This is also good for dieting. The high-protein components (chicken breast and Greek yogurt) keep you full for a long time, preventing overeating, and lemon juice lowers insulin resistance, inhibiting fat accumulation. The low GI (glycemic index) of salad and fruit stabilizes morning blood sugar, while olive oil activates metabolism with healthy fats. Overall, this low-fat, high-fiber combination is effective for weight loss.
However, when consuming olive oil and lemon juice on an empty stomach in the morning, it is advisable to start with about 1 teaspoon to avoid stomach irritation. Excessive fruit intake can cause blood sugar spikes, so it is important to maintain a moderate amount (about 50g) and balance calories according to individual body types.
