We never need to justify to others our diet or our body size. But I suppose our confidence in our choices will dictate how we respond. The more confident we are, the more lovingly we can convey the notion that we will not engage in discussing those choices. Instead of becoming combative and defensive, we can simply aver that our choices are our own and not open to discussion or judgment.
So the challenge is in realizing our own autonomy, and also that those who could criticize are quite possibly even less confident than we are.
