was kostet die abnehmspritze? — what can you do yourself?

The question about the cost of 'weight loss injections' (GLP-1 agonists like semaglutide) cannot be answered from the given context – no price information is provided. Costs vary widely by country, insurance, and brand (e.g., Ozempic, Wegovy, Mounjaro). In the US, out-of-pocket can be $300–$1,000+ per month; insurance may cover it for diabetes or severe obesity (BMI >30). What you can do yourself: Evidence-based weight loss relies on sustainable dietary changes (calorie deficit, high protein, fiber) and regular exercise (resistance and aerobic training). DNA tests (e.g., FTO rs9939609) show only a tiny effect on BMI – lifestyle dominates. Supplements or 'metabolism boosters' lack sufficient evidence. Beware of expensive, unproven products. Bottom line: injections are costly and not risk-free; self-directed diet and exercise remain the most important and safest lever.
