    One of the most common questions we get is "how quickly will I see results?". Here we provide a realistic timeline based on clinical studies and our clinical experience.

    Week 1-4: The Start-up Phase

    During the first month, most notice reduced hunger and appetite. Weight loss is usually 2-4 kg. The dose is low to let the body adjust.

    Month 2-3: Dose Escalation

    The dose is gradually increased and weight loss accelerates. After 3 months, most have lost 5-8% of their body weight. Side effects tend to decrease.

    Month 4-12: Active Treatment Phase

    The greatest weight loss occurs during this period. At 6 months, we often see 10-12% weight loss, at 12 months 12-15%.

    After 12 Months: Maintenance

    Weight loss plateaus and focus shifts to maintenance. Maximum effect is often seen after 15-18 months with total weight loss of 15-20%.

    Frequently asked questions

    Why is it slow at the beginning?
    We start with a low dose to minimize side effects. The effect increases as the dose is escalated.
    What if I'm not losing weight?
    If weight loss is insufficient after 3-6 months, we do an evaluation and adjust the treatment plan.
