Actor Kim Sa-rang, 48, recently shared a cheerful glimpse into her everyday routine centered around enjoying good food. On social media, Kim wrote, “Today, let’s just eat,” adding lightheartedly, “Did I gain weight? My happiness is gaining, too.” The message accompanied a photo of her dressed casually while enjoying samgyeopsal (pork belly) at a barbecue restaurant. As a former Miss Korea, Kim is widely celebrated for her meticulous self-care. Standing 173 cm tall and weighing 49 kg, her body mass index (BMI) calculates to roughly 16.4, which sits noticeably below the standard underweight threshold of 18.5.
Rethinking the Scale: BMI and Personal Health Metrics
BMI evaluates body fatness by dividing an individual's weight by the square of their height. According to guidelines established by the Korean Society for the Study of Obesity, a normal, healthy BMI ranges between 18.5 and 23. By these standard metrics, an ideal weight range for someone of Kim Sa-rang’s height would technically fall between 55.4 kg and 68.5 kg.
However, medical experts emphasize that weight alone does not dictate overall wellness. While contemporary cultural trends often idolize ultra-thin physiques and automatically associate higher weights with poor health, certain epidemiological studies suggest that individuals classified as slightly overweight or obese can exhibit lower overall mortality risks. Ultimately, BMI functions merely as a baseline; true metabolic health requires looking at comprehensive body composition, including muscle mass, body fat percentage, and skeletal frame.
Nutritional Benefits of Samgyeopsal and Vegetable Pairings
While samgyeopsal is traditionally viewed as a high-fat indulgence to be avoided during diets, it can serve as a beneficial option for individuals who are clinically underweight by helping replenish necessary caloric intake. Pork belly delivers high-quality protein containing essential amino acids vital for maintaining and building skeletal muscle mass. Furthermore, dietary fat is an essential macronutrient for women; maintaining an excessively low-fat diet can negatively disrupt the regulation and synthesis of female hormones.
Crucially, individuals with a naturally low BMI are unlikely to experience sudden weight gain from an occasional high-fat meal, as they often possess a higher basal metabolic rate or a lower baseline caloric intake that makes gaining weight difficult.
Maximizing the nutritional value of such a meal involves strategic pairings, as demonstrated by Kim Sa-rang's choice of side dishes like mushrooms and green onions. Mushrooms are low in calories yet dense in dietary fiber and beta-glucan, a compound known to increase satiety and curb overeating. Meanwhile, the allicin found in green onions aids cardiovascular circulation and offers natural antibacterial benefits. Green onions also provide essential micronutrients—including vitamin C, beta-carotene, and potassium—replenishing vital vitamins that a meat-centric dish lacks.
The Counterproductive Chemistry of Diet-Induced Stress
Chronic weight management often revolves around rigid calorie counting and strict dietary restriction. However, obsessing over caloric limits can generate profound psychological stress over time. Paradoxically, diet-induced stress can trigger weight gain by elevating systemic levels of the hormone cortisol.
A study published in the clinical journal Psychosomatic Medicine tracked 121 women divided into four experimental groups, revealing that participants who strictly restricted their food intake experienced a significant spike in cortisol production. As a primary stress hormone, cortisol elevates blood sugar levels and signals the body to preserve fat stores, directly increasing the risk of developing abdominal obesity. Consequently, medical professionals suggest that allowing oneself to occasionally prioritize emotional well-being and "gain happiness" through delicious meals—much like Kim Sa-rang—is a healthier, more sustainable approach to long-term wellness.
