Denormalized being overweight

Can we denormalize being overweight? Im not saying to shame people who are suffering from it due to trauma and medication, but instead of ignoring and letting them destroy themselves by encouraging we should rather focus on helping them to make them lose weight so they wont have any health issues nor immobility due to their big weight. And before you say "oh but you cant know if its unhealthy for them or not", you guys didn't have the same opinion when you saw the anorexic girl on tik tok. She is the other end of the spectrum where she is not obese but extremely thin which also has its health issues.
