How to Lose Weight Without Yo-Yo Effect — Why Jungnang-gu Korean Medicine Clinic Prioritizes "Recovery of Basal Metabolic Rate"
You've probably experienced this at least once: you successfully lost weight through dieting, but a few months later you're back to your original weight, or even heavier than before. The core reason this pattern repeats is a decrease in basal metabolic rate (BMR).
According to related clinical data, rapid weight loss can lower basal metabolic rate by 10-20%. This is because the body recognizes a 'starving state' and reduces energy consumption itself, a phenomenon called adaptive thermogenesis. The moment you stop restricting food intake, the remaining food is stored entirely as body fat in a structure already formed within your body.
The perspective Korean medicine clinics take on dieting starts at this point. Rather than reducing numbers through starvation, it's about recovering basal metabolic rate and reducing body fat primarily. According to clinical results, an average weight loss of 7.2kg over 2 months (based on an average follow-up period of 48 days) was achieved, which is the result of an approach that preserves muscle mass while reducing body fat.
However, even with the same herbal medicine, the prescription content varies depending on individual constitution and health status. It's important to first confirm through a consultation with a Korean medicine doctor whether the prescription is suitable for you.
✓ Key Summary
- Cause of yo-yo: Sudden dietary restriction → 10-20% decrease in basal metabolic rate → body fat stored even with minimal eating
- Korean medicine clinic approach: Increase basal metabolic rate without starving to reduce body fat primarily
- Important note: Customized prescription necessary after confirming constitution and health status
Why Yo-Yo Repeats — Starvation Dieting Actually Creates a Body Type That Gains Weight Easily
Many people think yo-yo is a matter of willpower, but in fact, it's closer to a physiological response of the body. Let's examine step by step why repeated dieting gradually transforms your body into a type that gains weight more easily.
✓ Step 1 — Starting Calorie Restriction When you drastically reduce the amount you eat, your body perceives the energy deficit as a 'crisis'. To survive, it begins lowering basal metabolic rate and breaks down muscle to use as an energy source.
✓ Step 2 — Weight Decreases but Muscle Mass Also Decreases While scale numbers drop, a significant portion of the decrease is muscle and water. When muscle decreases, the body's ability to consume energy itself becomes lower.
✓ Step 3 — The Moment You Stop Dietary Restriction With lowered basal metabolic rate, when you eat the same amount as before, excess energy rapidly accumulates as body fat. This is the weight cycling pattern that repeats. This is the repetition of the weight cycling pattern.
✓ Step 4 — The Next Diet Becomes Even Harder When you start dieting again with a higher body fat percentage, you need to eat much less to achieve the same effect as before. The vicious cycle intensifies.
From a Korean medicine perspective, reckless fasting damages the spleen and stomach's (脾胃) transportive and transformative function (運化), which is the ability to digest, absorb, and metabolize nutrients. When this function weakens, it leads to retention of dampness (水濕) in the body—a state of spleen deficiency (脾虛)—and hardens into a constitution where you swell easily and lose weight with difficulty even with minimal eating. Related clinical data shows that this Korean medicine pathophysiological mechanism is explained in a direction similar to the concept of metabolic decline in modern medicine.
Early intervention to recover both basal metabolic rate and spleen-stomach function is key to breaking the yo-yo cycle.
mail100yr kmd Maildambi Hwan — Body Fat-Focused Weight Loss Design Built on 10 Years of Clinical Experience
Dr. Song Won-seok of mail100yr kmd began research personally for his wife whose weight did not return to normal after childbirth, and based on Maildambi Hwan, which he has improved for over 10 years, he maintains honest clinical principles of personally taking it and prescribing it to his family.
The core design of Maildambi Hwan has two aspects: reducing weight focusing on body fat through appetite control and increased basal metabolic rate without starving, and 1-8 stage micro-dosage adjustment to immediately respond to different reactions from individual to individual.
A 2024 study in the Journal of Korean Medicine and Life Science (KCI-registered) reviewed the safety of applying ephedra and ephedrine for obesity treatment and discussed evidence for their application under appropriate prescription by Korean medicine doctors. The fact that Maildambi Hwan contains ephedra (ephedrine) component is disclosed transparently from the start, and the principle is not to forcibly prescribe if it doesn't match constitution.

Before Starting Herbal Diet Medicine, Those with These Conditions Should Check First
Before starting, check the following items. Those with more applicable items should thoroughly confirm during the consultation stage for safety.
✓ Those with hypertension and cardiovascular disease or family history The ephedrine and pseudoephedrine components in ephedra work by stimulating the sympathetic nervous system to increase energy consumption. According to related clinical data, this component can affect heart rate and blood pressure, so those with cardiovascular problems must inform us in advance.
✓ Those with usual insomnia or decreased sleep quality It can affect sleep due to sympathetic nervous system stimulation effects. If uncomfortable reactions such as headache, nausea, or insomnia appear during intake, immediate management through 1-8 stage dosage adjustment is possible.
✓ Those with concerns about liver function Based on 17,089 prescriptions, abnormal liver enzyme incidence is managed within 0.3%, but those with underlying liver disease must definitely inform us during consultation.
✓ Those who are pregnant or planning pregnancy Herbal medicine intake requires consultation before starting.
✓ Those who have repeated dieting 3 or more times and experienced yo-yo each time When weight cycling repeats, basal metabolic rate decline may be more severe, making it advantageous to design both the weight loss period and yo-yo management period together.

Diet Without Yo-Yo, Frequently Asked Questions
Q1. If I stop taking diet herbal medicine, won't yo-yo come back?
It's more important to recover basal metabolic rate and establish lifestyle habits together during the herbal medicine intake period rather than the herbal medicine intake itself. For this reason, we recommend combining a 6-month yo-yo management package after weight loss completion. Rather than stopping suddenly, it's more advantageous for weight maintenance to gradually adjust the prescription amount while finishing.
Q2. I heard Maildambi Hwan contains ephedra (ephedrine)—is it safe?
The fact that ephedra (ephedrine) component is included is disclosed transparently from the start. In a KCI-registered academic journal (Journal of Korean Medicine and Life Science 2024), safety evidence under appropriate prescription by Korean medicine doctors has been reviewed. Based on 17,089 prescriptions, abnormal liver enzyme incidence is managed within 0.3%. If uncomfortable reactions such as headache, nausea, or insomnia occur, we immediately address them through 1-8 stage dosage adjustment.

Yes, you can receive consultation and prescription via mail delivery through non-face-to-face consultation from anywhere in Korea. For those who cannot visit in person, constitution confirmation and prescription design are possible through online consultation, so please feel free to inquire.
Q4. Is it effective for menopausal women and women in their 40s-50s?
Before and after menopause, basal metabolic rate noticeably drops along with changes in female hormones, making it a time when body fat easily accumulates.

Through consultation, we will first confirm the stage suitable for your current constitution and health status.
