The Rise of Weight-Loss Injections: What the Latest Tests Reveal
The quest for effective weight loss solutions continues, with a growing focus on injectable medications. Recent testing by Stiftung Warentest, Germany’s leading consumer organization, has shed light on the efficacy and risks associated with these treatments, currently available in Germany. The analysis of 17 different weight-loss products, encompassing four active ingredients, reveals a nuanced picture: while some indicate promise, others are deemed ineffective or carry unacceptable risks.
Two Ingredients Stand Out
The Stiftung Warentest findings highlight two active ingredients – Tirzepatide (marketed as Mounjaro) and Semaglutide (marketed as Wegovy) – as the most promising options. These medications, when combined with lifestyle changes, demonstrate significant weight loss potential. Tirzepatide, administered weekly, can lead to a 13-19% weight reduction over a year when coupled with a calorie-controlled diet and increased physical activity, with effects largely sustained after three years. Wegovy, also a weekly injection, shows a potential for 9-12% weight loss after one year, stabilizing after two years.
These medications perform by mimicking natural hormones in the body, increasing feelings of fullness, slowing down stomach emptying, and regulating blood sugar levels. They are not simply “fat-melting” injections, but rather impact core metabolic processes.
Other Treatments Fall Short
The evaluation wasn’t universally positive. Liraglutide (Saxenda), a daily injection, showed less impressive results, with only 4-5% weight loss after a year and a higher incidence of severe side effects. Orlistat, a fat blocker available in both prescription and over-the-counter forms, yielded minimal weight loss – just 2-4% after two years.
The Importance of Lifestyle Changes
Experts emphasize that these medications are not a standalone solution. Dr. Claudia Michael, a health expert at Stiftung Warentest, stresses the critical role of lifestyle modifications. “I strongly advise against relying solely on medication. Accompanying lifestyle changes – more exercise and a reduced calorie intake – are crucial for long-term success.” these medications can lead to muscle loss, making strength training and a protein-rich diet essential.
Long-Term Considerations and Costs
Both Tirzepatide and Semaglutide are relatively new to the market, meaning long-term effects beyond two to three years remain largely unknown. Weight regain is also a common concern after discontinuing treatment. A significant barrier to access is cost. Currently, these medications are not covered by statutory health insurance in Germany, as they are classified as lifestyle drugs. Costs range from approximately €43 to €122 per week, potentially exceeding €500 per month.
Similar costs are observed in Austria, ranging from €200 to €580 per month for private payers, with coverage typically limited to cases where obesity is linked to Type 2 diabetes.
Risks of Online Purchases
The Stiftung Warentest also issued a warning about the ease with which these injections can be obtained online. A recent investigation by the Verbraucherzentrale NRW (consumer advice center) found that some telemedicine platforms require minimal verification of identity or body weight, potentially allowing access to individuals who may not be suitable candidates.
