On a recent broadcast, Lim revealed her go-to fitness habit: light stretching and running before breakfast. While it’s not always easy, she says the routine has had a major positive impact on her health and body.
Stretching activates multiple muscle groups, promotes fat burn, boosts metabolism, and supports digestive health. When done first thing in the morning, it’s especially effective for weight loss and obesity prevention.
Running is a full-body cardio workout that strengthens endurance and torches calories—about 700 kcal per hour for a 70kg adult. In a fasted state, the body burns fat more efficiently, making it a powerful weight-loss strategy.

With insulin and blood sugar levels low after a night’s sleep, the body taps into fat stores for energy—especially targeting stubborn belly fat.
Fasted exercise can enhance insulin sensitivity, helping to manage blood sugar more effectively and potentially preventing type 2 diabetes and metabolic syndrome.
Morning workouts increase oxygen flow to the brain and activate neurotransmitters, improving focus and reducing stress—perfect for busy professionals or students.

Fasted workouts aren't for everyone. High-intensity exercises like weightlifting or HIIT on an empty stomach may cause dizziness, fatigue, or even muscle loss. For those sessions, a light snack—like a banana—is recommended.
And don’t forget hydration. Fasting increases the risk of dehydration, so drinking water before and after exercise is essential.
Lim Ji-yeon’s disciplined routine is more than just a trend—it’s a lifestyle choice that combines physical fitness with long-term health. Her tip? Keep it light, stay consistent, and listen to your body.
