I never thought of it that way - not wanting to know your weight is part of not accepting yourself. Hmmmm. It is a question of just not being afraid of a number or letting a number define you.
However, adding to weight should not be a concern either - unless it is for an unexplained reason. The thing is you can be healthy at any size - to me there is no such thing as a “healthy weight”—If I weigh 350 pounds today, but don’t eat well and don’t exercise - I may be unhealthy; however, if I start to exercise and eat better, I may still weigh 350 pounds, but be healthier. Weight doesn’t make you healthy - it’s the behavoir of the person.
