Despite approaching her 50s, MC Kim Jun Hee maintains an enviably toned and slim figure. On her YouTube channel, Life of JUNIE, she reveals three essential habits that have helped her maintain a 47 kg weight for 30 years.
1. Morning Warm Water
Upon waking up, Kim Jun Hee starts her day with a glass of warm water. She believes that the body loses significant water during sleep, so drinking warm water in the morning boosts metabolism, warms the body, and supports organ function more effectively.

Kim Jun Hee shares three key habits for maintaining her 47 kg weight for 30 years.
Kim Jun Hee never drinks cold water, even in hot weather, as she believes it can slow down absorption and negatively affect digestion. Experts also recommend warm water in the morning to protect the stomach lining, aid digestion, and enhance the body’s detoxification process.
2. Fasted Cardio
According to Kim Jun Hee, performing cardio exercises before breakfast helps burn excess carbohydrates more efficiently, aiding weight loss and rapid fat removal. Research also indicates that working out before breakfast can increase fat burning by about 20% compared to post-meal workouts. However, this method can lead to muscle loss if done for extended periods. Thus, experts recommend limiting fasted cardio to 20-30 minutes and consuming protein immediately afterward, such as eggs, tofu, or protein powder, to protect muscle mass. Individuals with blood sugar concerns should also be cautious, as fasting workouts can increase cortisol levels, affecting insulin production and blood sugar fluctuations.

Kim Jun Hee attributes fasted cardio as a key factor in burning excess carbohydrates.
3. 16:8 Intermittent Fasting
To maintain her figure, Kim Jun Hee adopts a 16:8 intermittent fasting approach, eating only during an eight-hour window and fasting for the remaining 16 hours. She typically ends her dinner by 6 PM to allow sufficient time for energy metabolism. This method is believed to be effective for weight loss as insulin levels significantly decrease after about 12 hours of fasting, promoting fat burning. In addition to weight control, intermittent fasting offers benefits for cardiovascular health, brain function, and blood sugar regulation.
