Weight loss drugs like Ozempic, GLP-1s, and Mounjaro have taken the world by storm. Celebrities, friends and even your neighbours are trying them. They promise fast results with minimal effort. But according to Dr Robert Kiltz (Founder and Director of CNY Fertility), these medications may not be the miracle solution everyone thinks. In fact, they can backfire horribly.
Why Weight Loss Drugs Aren’t A Permanent Solution
Dr Kiltz explains that medications like GLP-1s work by suppressing your appetite. He says, “Your brain says eat, and the drug says no. The medication is doing all the work for you.” That might sound great initially, but there’s a hidden catch. Studies show that about two-thirds of people who lose weight using these drugs regain most of it within a year. For example, if someone loses 45 lbs, they may gain back 30 lbs after stopping the medication.
Dr Kiltz says, “Weight loss drugs don’t teach your body anything. They don’t build healthy habits or change your relationship with food.” When users stop the medication, the appetite rebounds quickly, sometimes even stronger than before. Many people may also experience muscle weakness, metabolic issues or gastrointestinal side effects during and after use.
Sustainable Weight Loss Comes From Diet And Lifestyle
According to Dr Kiltz, a proper diet (like Paleo, Keto or a carnivore-style plan) combined with exercise and community support is far more effective for long-term results. He explains, “When you change your mindset first, your brain learns to sustain weight loss naturally.”
Research supports this. People who commit to lifestyle changes can maintain 5–10% weight loss for one to two years or more, along with improved metabolic health, better insulin control, stronger cardiovascular health, and reduced inflammation. Beyond physical results, diet-based weight loss also improves mental health, confidence and emotional resilience (benefits that weight loss drugs cannot deliver).
Even minor adjustments, such as walking daily, eating real food and building a supportive community, can lead to lifelong habits. Unlike expensive medications, these changes cost little, last a lifetime, and come with no risky side effects.
Dr Kiltz stresses that while weight loss drugs may offer a temporary shortcut, real transformation happens through disciplined lifestyle changes. He says, “Easy fixes are tempting, but sustainable health requires effort, consistency, and a diet your body can actually thrive on.”
To sum it up, weight loss drugs can work for short-term results, but most users regain the weight and face side effects. Sustainable, lasting health comes from diet, exercise and mindset change. If you want long-term results, invest in real habits, not just medications.
