Dr. Yan Sumei reply Traditional Chinese Medicine


Fat-burning teas are generally composed of bitter and cold herbs.
The bitter and cold properties primarily promote anti-inflammatory effects and reduce internal heat.
However, individuals with a deficiency in cold constitution may experience digestive issues, hormonal imbalances, joint pain, and symptoms such as cold hands and feet or frequent urination during winter if they consume too much.
Therefore, it is advisable for those with a cold deficiency constitution to limit their intake.
Thank you for your message, and I wish you health and safety.

More Info


Long-term consumption of fat-burning teas, often marketed in traditional Chinese medicine clinics, raises several concerns regarding potential side effects. These teas typically contain a variety of herbal ingredients, many of which may have strong pharmacological effects. While some individuals may experience benefits from these teas, it is essential to consider the possible adverse effects associated with their prolonged use.

Firstly, many fat-burning teas contain ingredients that are classified as "bitter cold" herbs in traditional Chinese medicine. These herbs are believed to have anti-inflammatory and detoxifying properties. However, for individuals with a "deficient cold" constitution—characterized by symptoms such as digestive issues, cold extremities, and fatigue—excessive consumption of these teas can lead to gastrointestinal discomfort, including bloating, diarrhea, or constipation. This is due to the herbs' strong effects on the digestive system, which can exacerbate existing conditions in sensitive individuals.

Moreover, some fat-burning teas may contain stimulants such as caffeine or other compounds that can lead to increased heart rate, anxiety, or insomnia, especially when consumed in large quantities. Caffeine is known to have diuretic properties, which can lead to dehydration if fluid intake is not adequately maintained. Dehydration can further contribute to digestive issues, including constipation, which is a common concern among those who consume high amounts of caffeinated beverages without sufficient water intake.

Another critical aspect to consider is the potential for herbal interactions. Many fat-burning teas may interact with prescription medications or other herbal supplements, leading to unintended side effects or reduced efficacy of medications. For instance, certain herbs can affect liver enzymes responsible for drug metabolism, which may alter the effectiveness of medications taken concurrently.

Additionally, the long-term effects of consuming herbal teas that claim to promote fat loss have not been extensively studied. While some ingredients may have short-term benefits, the long-term safety profile remains unclear. Continuous reliance on these teas for weight management may lead individuals to neglect healthier lifestyle choices, such as balanced nutrition and regular physical activity, which are crucial for sustainable weight loss.

Lastly, it is essential to consider the quality and source of the fat-burning tea. Many commercially available products may contain additives, preservatives, or low-quality herbal ingredients that could pose health risks. It is advisable to choose products from reputable sources and to consult with healthcare professionals before incorporating any new herbal supplement into your routine.

In summary, while fat-burning teas may offer some benefits, long-term consumption can lead to various side effects, particularly for individuals with specific health conditions or sensitivities. It is crucial to approach these products with caution, prioritize a balanced diet and lifestyle, and consult with healthcare providers to ensure safe and effective use.
