Opinion: Weight-Loss Injections Like Mounjaro Offer False Promise, Expert Warns

Popular injectable weight-loss drugs such as Mounjaro, Wegovy, and Ozempic — medications that suppress appetite by mimicking gut hormones — may cause serious metabolic and muscular side effects, according to a commentary by fitness and nutrition expert Miloš Malejčík. While the drugs effectively reduce hunger, Malejčík argues that users risk long-term damage to their metabolism and significant loss of muscle mass in exchange for short-term weight reduction. The opinion piece warns that relying on these injections without addressing underlying lifestyle habits amounts to a costly trade-off that undermines the body's natural biological processes.
