From the Guidelines
There is no single herbal supplement that has been scientifically proven to be effective for weight loss, and lifestyle changes such as a calorie-controlled diet and regular physical activity remain the most effective approach to achieving and maintaining weight loss. The most recent and highest quality study, published in 2024 in the journal Diabetes Care 1, emphasizes that despite widespread marketing and exorbitant claims, there is no clear evidence that nutrition supplements, including herbs and botanicals, are effective for obesity management or weight loss. Several large systematic reviews show that most trials evaluating nutrition supplements for weight loss are of low quality and at high risk for bias, with high-quality published studies showing little or no weight loss benefits.
Some key points to consider when evaluating weight loss supplements include:
- The lack of substantial scientific evidence supporting their use for weight loss
- The potential for side effects and harmful interactions with medications
- The importance of consulting with a healthcare provider before trying any supplement, especially for individuals with existing health conditions
- The need for a comprehensive approach to weight management that includes a calorie-controlled diet, regular physical activity, and behavioral changes.
It's also important to note that some commercial and proprietary weight loss programs may show promising results, but many lack evidence of effectiveness and may promote unscientific and possibly dangerous practices 1. In contrast, vitamin/mineral supplementation may be indicated in cases of documented deficiency, and protein supplements may be indicated as adjuncts to medically supervised weight loss therapies 1.
Overall, the best approach to weight loss is a comprehensive and sustainable one that incorporates lifestyle changes, rather than relying on supplements or quick fixes. A calorie-controlled diet and regular physical activity, combined with behavioral changes and ongoing support, are the most effective ways to achieve and maintain weight loss.
From the Research
Herbal Supplements for Weight Loss
- The effectiveness of herbal supplements for weight loss is a topic of ongoing research and debate 2, 3, 4, 5, 6
- Some studies suggest that certain herbal supplements, such as green tea, may have a small, statistically non-significant effect on weight loss 3
- However, the evidence is not conclusive, and more research is needed to fully understand the potential benefits and risks of herbal supplements for weight loss 2, 4, 6
Safety Concerns
- Some herbal supplements, such as ephedra and ephedrine-containing supplements, have been associated with safety concerns, including hepatic injury and death 4
- Other herbal supplements, such as Garcinia cambogia and yerba mate, may be safer and merit further investigation 4
- It is essential to consult with a healthcare professional before using any herbal supplement, especially if you have any underlying medical conditions or are taking prescription medications 5, 6
Counseling and Regulation
- Pharmacists and non-pharmacists may provide varying levels of counseling to patients regarding herbal weight loss supplements, highlighting the need for standardized education and training 5
- The regulation of herbal supplements is often inadequate, and more resources are needed to ensure the safety and efficacy of these products 6
- Cooperative interactions between regulatory agencies, research institutions, and healthcare professionals are crucial for advancing our understanding of herbal supplements and their potential role in weight loss 6
