In a world inundated with weight loss strategies, a simple search online or a scroll through social media reveals a plethora of tips, tricks, and products promising rapid weight loss. Among these is a novel contender: weight loss patches. However, experts warn that these patches, often marketed as groundbreaking solutions, may not be as effective as they claim.
From plant-based supplements like berberine to viral TikTok trends like ‘rice-zempic,’ many weight loss fads have proven disappointing. Weight loss patches, which promise to deliver fat-burning or metabolism-boosting ingredients through the skin, have come under scrutiny. According to Dr. Jorge Moreno, an internal medicine physician specializing in obesity at Yale Medicine, these patches can lead to adverse side effects and lack regulatory oversight, leaving consumers unaware of their actual contents.
Understanding Weight Loss Patches
Weight loss patches are adhesive stickers designed to be applied to areas of the body where users seek to lose weight, such as the abdomen, arms, or thighs. Some patches utilize transdermal absorption, meaning the active ingredients are meant to permeate the skin, theoretically assisting in fat burning and boosting metabolism. Dr. Dina Peralta-Reich, founder of New York Weight Wellness Medicine, notes that these patches are widely available on major online platforms and in nutrition stores.
Unlike traditional oral supplements, which must pass through the digestive system, these patches aim to deliver ingredients directly into the bloodstream, a key distinction noted by Dr. Charlie Seltzer, a weight loss physician and exercise physiologist in Philadelphia. Typical ingredients found in these patches include Japanese mint, green tea extract, green coffee bean extract, and bitter orange, often accompanied by essential oils for skin hydration. Users are generally instructed to wear the patches for six to eight hours, three to four times a week.
Do These Ingredients Have Weight Loss Benefits?
While some ingredients in these patches, such as caffeine, may slightly enhance heart rate or metabolism, the overall impact on weight loss is minimal. The lack of regulation means it is challenging to assess the safety and effectiveness of these patches, as the precise amounts of active ingredients remain unknown.
Dr.Seltzer emphasizes that current research does not support the efficacy of the ingredients in these patches, even if they were administered through the bloodstream. Here’s a closer look at some common ingredients:
Green Tea Extract: Although some studies suggest that caffeine and green tea may assist in weight management, these effects are not substantial. Notably, excessive use of green tea supplements has been linked to rare cases of liver damage.
Green Coffee Bean Extract: Derived from unroasted coffee beans, this extract contains chlorogenic acid, which some studies suggest may aid weight loss. However, these results were obtained through oral consumption, not transdermal application, making comparisons difficult.
Hokuto Mint: Known for its menthol content, this mint has been claimed to inhibit sugar absorption, but there is no research to support its weight loss efficacy.
Ephedra: Known for its dangers, ephedra was banned by the FDA in 2004 due to severe health risks, including heart attacks and strokes.
Bitter Orange Extract: Often marketed as a weight loss aid, this extract contains synephrine, which may promote calorie burning but with limited effects, as noted in a 2017 study.
Ashwagandha: While this herb can reduce stress-related eating by lowering cortisol levels, it does not guarantee weight loss.
Cannabidiol (CBD): Emerging as a popular remedy for anxiety and pain, CBD patches may have appetite-suppressing effects, but conclusive research is still lacking.
Garcinia Cambogia: Though touted for its ability to block fat production and suppress appetite, research shows only minimal weight loss effects and potential side effects, including headaches and liver issues.
Potential Risks of Weight Loss Patches
The FDA does not regulate weight loss patches or dietary supplements, leaving room for adverse effects such as nausea, headaches, increased heart rate, and skin irritation. Dr. Peralta-Reich warns that these products often include a combination of ingredients that can lead to serious health risks.
“Many patches market themselves as entirely natural, yet they may contain substances that induce tachycardia and other negative effects,” she explains. “I typically do not recommend them due to the lack of scientific evidence supporting their efficacy in weight loss.”
Do Weight Loss Patches Actually Work?
Dr. Seltzer asserts that these patches are ineffective for quick weight loss, regardless of accompanying exercise or dietary measures. The allure of trendy ingredients contributes to unrealistic expectations, but he explains that the physiological effects of these ingredients, particularly in small and inconsistent doses, are negligible.
Dr. Moreno adds that the application site of the patch has no bearing on its effectiveness. “If these patches were truly effective, they would work on any skin area. The lack of evidence supporting their use means they would not be part of my practice in obesity medicine,” he states.
Is It Safe to Try Weight Loss Patches?
Before experimenting with weight loss patches, consulting a healthcare provider is crucial. While these patches are generally not harmful, they are often ineffective and unlikely to provide a worthwhile return on investment.
Recommended Strategies for Effective Weight Loss
Experts stress that physical activity is essential for weight loss. Dr. Moreno advises finding enjoyable exercises, whether it’s walking, swimming, or dancing, and setting small, achievable goals to gradually increase activity duration.
Incorporating resistance training can also be beneficial, starting with bodyweight exercises before adding light weights or resistance bands. Dr. Moreno encourages dietary modifications, particularly increasing fiber intake with foods like broccoli, sweet potatoes, beans, and lentils, which promote satiety without excessive calories.
Dr. Peralta-Reich recommends focusing on nutrient-dense foods, such as fruits, vegetables, and lean proteins, which support overall health and weight loss. Healthy fats from fish, nuts, and oils can improve cholesterol levels and reduce heart disease risk. While carbohydrates should not be avoided, opt for whole grains like brown rice and quinoa.
Limiting alcohol and sugary beverages while increasing water intake is advisable, as is avoiding processed meats and saturated fats. For those struggling to lose weight, a consultation with a doctor or registered dietitian can provide tailored guidance and support in reaching weight loss goals.
