Hamburg, Germany – August 19, 2025 – New medications are offering notable weight loss results, prompting both excitement and scrutiny. Health expert Sascha Bade provides an insightful look at the efficacy and sustainability of thes injections, addressing critical questions about their long-term impact.
The Rising Popularity of Weight Loss Injections
Injections like Wegovy and Saxenda are generating considerable buzz due to their demonstrable effects. Individuals struggling with weight for years are reporting substantial losses – often in the double digits within months.Though, this rapid progress raises critically important questions about how these medications work, what happens when treatment ends, and whether lasting success is truly achievable.
How Do These Injections Work?
medications containing semaglutide (Wegovy) and liraglutide (Saxenda) were initially developed to treat type 2 diabetes.Research revealed that these drugs not only regulate blood sugar but also suppress appetite, sometimes leading to significant reductions in food intake. These medications belong to a class of drugs known as GLP-1 receptor agonists.
GLP-1 stands for glucagon-like peptide-1, a naturally occurring hormone produced in the intestine that helps regulate appetite. Artificial GLP-1 analogues mimic this hormone, but with a longer-lasting and more potent effect. They slow gastric emptying, promote feelings of fullness, and influence brain regions involved in hunger and reward pathways.
Did You Know? The body’s natural GLP-1 hormone plays a crucial role in regulating appetite and blood sugar levels, making it a key target for weight management therapies.
Quantifying Weight Loss Results
Large-scale clinical trials have demonstrated that, in combination with lifestyle changes, individuals using these medications can lose approximately 15% of their initial body weight within a year. For a person weighing 100 kilograms (220 pounds), this translates to roughly 15 kilograms (33 pounds) of weight loss. Individual results vary, with some experiencing more substantial reductions than others.
| Medication | Active Ingredient | Average Weight Loss (1 year) | Requires Lifestyle Changes? |
|---|---|---|---|
| wegovy | Semaglutide | ~15% of initial body weight | Yes |
| Saxenda | Liraglutide | ~5-8% of initial body weight | yes |
Crucially, the most significant results were observed in participants who also adopted healthier diets and increased their physical activity. These medications are not a shortcut to weight loss but rather a tool to facilitate positive lifestyle changes.
The Critical question: What Happens When You Stop?
The long-term sustainability of weight loss achieved through these injections is a primary concern. A 2022 study revealed sobering findings: after discontinuing semaglutide, many participants experienced significant weight regain, averaging approximately two-thirds of their initial weight loss within one year. The positive effects on blood pressure, blood sugar, and cholesterol levels also diminished considerably.
Without ongoing lifestyle modifications, the benefits of these medications are unlikely to be sustained. the drug addresses the symptom of obesity – excess weight – but doesn’t fundamentally alter metabolism or eating behaviors. As soon as the medication is stopped, old patterns often resurface, leading to weight regain.
Pro Tip: Consider these injections as a catalyst for long-term lifestyle changes, not a standalone solution. Focus on building sustainable habits around nutrition and exercise.
Understanding the Yo-Yo Effect
The cyclical pattern of weight loss and regain, commonly known as the yo-yo effect, occurs when rapid weight loss isn’t maintained through sustainable practices. This is driven by two key mechanisms:
- Metabolic Adaptation: When calorie intake is reduced, the body adapts by lowering its energy expenditure – a protective evolutionary response to famine.
- Appetite Rebound: Discontinuing medication can lead to a resurgence of appetite. Without learned coping mechanisms for managing hunger, stress-induced eating, or emotional eating, individuals may revert to previous habits.
Do you find yourself struggling with emotional eating or finding it difficult to maintain a healthy diet? Understanding your triggers is the first step towards lasting change.
Achieving Long-Term Success
Weight loss injections can be a valuable tool for initiating successful weight loss, but they are not a panacea. To achieve lasting results, a holistic approach to health is essential. These medications are most effective when integrated into a complete health plan.
This includes personalized nutritional strategies tailored to individual needs and lifestyles, avoiding restrictive diets and focusing on sustainable changes. Regular physical activity, even moderate exercise like walking, swimming, or cycling, is also crucial. Addressing the psychological aspects of eating is equally important, as many individuals eat in response to emotions or stress. Professional support from therapists, coaches, or behavioral training can be invaluable.
ongoing medical supervision is necessary to monitor treatment, address potential side effects, and adjust the plan as needed.
Sascha Bade’s Conclusion
Weight loss injections can be a powerful lever for initiating weight loss, reducing pressure, and providing quick, visible results. This is particularly important given the serious health consequences associated with obesity. However, they do not automatically change habits, diet, or the relationship with food. Without accompanying lifestyle changes, the yo-yo effect remains a significant risk.
The injection can open the door, but ultimately, it’s up to the individual to walk through it.
The landscape of weight management is constantly evolving. Beyond injections, research continues to explore the role of gut microbiome, personalized nutrition, and innovative exercise strategies. The increasing prevalence of obesity globally underscores the need for multifaceted approaches that address both biological and behavioral factors. The future of weight loss will likely involve a combination of pharmacological interventions, lifestyle modifications, and ongoing support systems.
