A 20% reduction is not realistic or appropriate for everyone. It is a large milestone, not the definition of successful weight management.
Trial averages are not your target

What you can do next
Choose goals that reflect your health and circumstances. Discuss a personal weight target with your clinician where treatment is involved.
