Carbs burn first
When you eat, carbohydrates, proteins and fats become energy through digestion, absorption and metabolism. Among them, the body uses carbohydrates first.
TheLINE
If your lifestyle is not treated,
your diet will keep failing
Yo-Yo Free Diet
At TheLINE, we believe the root cause of overweight and obesity is related to internal imbalance. That is why this is a healthy diet program that helps with fundamental body-balance improvement and a shift toward a more positive lifestyle, rather than short-term weight loss alone.
LAST Diet Program
The TheLINE LAST Diet is not a diet that only sheds weight. It is a program that changes your body balance and your lifestyle together.

Starvation diets can lead to hair loss, irregular menstruation and weakened immunity. The LAST Diet changes your body balance while you keep eating.
We do not rely on drugs that strain the body, such as appetite suppressants. Getting your metabolism to run on its own comes first.
Instead of pushing you through workouts, we restore energy metabolism to its normal cycle. Once metabolism recovers, the body uses fat on its own.
At TheLINE, we see overweight and obesity as related to internal imbalance. A typical diet is about losing weight, while the TheLINE diet is about losing weight while regaining a healthy life.
Fat Metabolism
When your body's metabolism is not working smoothly, the energy you consume is not burned and remains as fat.

When you eat, carbohydrates, proteins and fats become energy through digestion, absorption and metabolism. Among them, the body uses carbohydrates first.

When high carbohydrate levels persist, the fat-breakdown pathway inside cells shuts down. A vicious cycle begins, running from irregular eating habits to energy shortage during fasting periods and on to weight gain.

Regular meals, nutritional balance including arginine, and body care bring energy metabolism back to its normal cycle. Stubborn fat that still does not go away is addressed with liposuction.

The ultimate goal of the LAST Diet is fundamental improvement of eating habits and normalization of metabolism. Once your body balance changes, the results follow.
※ Overeating or frequent snacking halts fat metabolism.
Life Style Transformation
Some patients tell us that once they changed the way they live, not only their weight but also their fatigue changed.

PREGNANCY RESTORED
Some patients have shared news of pregnancy after correcting their body balance and lifestyle.

CYCLE RESTORED
There are cases in which menstruation resumed as hormonal and metabolic balance settled back in.

LESS PERIOD PAIN
Some patients say the menstrual pain they had every month became much lighter.

OFF DIABETES MEDS
There are cases in which medication was reduced or discontinued while continuing blood glucose monitoring and dietary correction.

OFF SLEEP MEDS
Some patients say falling asleep became easier while receiving sleep treatment alongside the program.

OFF DEPRESSION MEDS
There are cases in which medication was gradually reduced as the sense of fatigue lifted.
※ Progress and changes may differ depending on individual condition and lifestyle. Any adjustment or discontinuation of medication you are taking must be decided in consultation with your attending physician.
Program Information
Check the tests, treatment intervals and precautions in advance.

Diagnosis Treatment Care
Because imbalance, nutritional deficiency and detoxification factors differ from person to person, TheLINE begins with an accurate diagnosis.
DIAGNOSIS
We find the causes of overweight and obesity through fat metabolism testing, more than 100 blood tests, physician diagnosis and analysis, 24-hour blood glucose monitoring, environmental pollutant testing and food allergy testing.
TREATMENT
Cognitive behavioral therapy, nutritional correction, exercise therapy, sleep therapy, stress relaxation therapy and lifestyle correction are combined with prescriptions and device-based procedures, tailored to each individual.
MAINTENANCE
Care continues with body composition, size and weight checks, diet and exercise checks, treatment result checks, blood glucose monitoring and lifestyle change checks by our medical team.
※ Contrary to common belief, the bodies of overweight and obese individuals are often in a state of nutritional imbalance that requires supplementation of lipids, proteins, carbohydrates and minerals.
Last Diet Care Program
Imbalance, nutritional deficiency and detox factors differ by person, so diagnosis comes first and treatment is tailored to each individual.
Arginine Injection Therapy
Nitric oxide, metabolic activation and protein synthesis restore the cycle.
Arginine injection
Arginine is a type of amino acid that helps synthesize the nitric oxide the body needs, supporting the treatment of obesity.
Mitochondrial PGC-1α
Nitric oxide activates the enzyme that hydrolyzes triglycerides in fat tissue and regulates the gene expression involved in producing mitochondria, the body's energy factories. When PGC-1α gene expression increases, mitochondrial synthesis increases and metabolism becomes more active, shifting the body toward a state that does not gain weight easily.
Without exercise
It suppresses fat and glucose production in the liver, so you can expect metabolic benefits similar to exercising even without working out.
Balance Micronutrient Therapy
From digestive imbalance to immune imbalance, we correct the causes of a weight-gaining body balance one by one.
BALANCE minerals
When digestion, absorption and metabolism do not work smoothly, the energy nutrients you consume are not used and remain as fat.
Deficiency · excess
Vitamins, minerals, amino acids, lipids and enzymes must all function properly to maintain a healthy state. Even a deficiency or excess in just a few of them leads to imbalance.
Heavy metal test
Heavy metal testing and environmental pollutant testing identify and correct the detoxification factors that differ from person to person.
Body balance
We gradually rebalance a body that gains weight because of imbalance. It also supports pre- and post-operative recovery, anti-aging and wellbeing for a healthy life.
※ The human body contains about 10 water-soluble vitamins, 4 fat-soluble vitamins, 13 major minerals, 9 essential amino acids, 9 non-essential amino acids, 11 types of lipids and more than 500 enzymes.
Recommendation Target
After countless diets that worked and failed, start by finding the cause.
For those who do not lose weight even with exercise and diet control combined.
For those who want to diet without harming their health.
For those who want body balance improvement and fat breakdown at the same time.
For those who want care aimed at maintaining the weight they have lost.
For those who want body care alongside their liposuction recovery.
For those who have succeeded and failed at countless diets and want to reclaim their health.

The LINE's Special
Designed by TheLINE, studying fat and metabolism since 2007.

With a questionnaire and blood tests covering more than 100 items, we accurately diagnose the root causes of overweight and obesity and provide treatment tailored to each patient.

We put lifestyle correction first, covering the eating habits, daily habits and sleep that get in the way of weight control. By raising metabolic and fat-breakdown capacity, we work toward a body that does not gain weight easily.

Because it does not drastically cut food intake or rely on appetite suppressants, there are no side effects such as constipation, loss of vitality or fatigue. It helps resolve nutritional imbalance and supports blood circulation and recovery from fatigue, adding a health benefit as well.

Because we correct the underlying causes of obesity and improve body balance, the results hold steady without the yo-yo effect.
