If its got in your way to health or just try to look fit.then yes
But if you will over-worry about how you look in others' eyes ,then you have to fix that problem before you set out to shed some weight.

When you watch a drama in which there are kings and you wont really think those players are kings ,right? so what matters really?

health is a mental and physical state. whne you are healthy , you look good while you feel great.
