Seeing 90 kg on the scale is often a “wake-up call” for my patients. It’s a weight where the BMI often crosses from ‘overweight’ into ‘obese’ for many people, and that can be a difficult milestone to process. In my clinical experience, 90 kg is a point where taking proactive steps—like reducing ultra-processed foods and increasing daily step counts—can yield significant results before more formal medical interventions become necessary. It’s a key time to focus on long-term metabolic health.
