Oh – and deprogram yourself from having this thought – much less saying it!
Your body is yours and it comes with its own unique bio-map. You can’t control that part, but you can control it’s inputs and have an excellent relationship with it. When you do this, it makes it easier for you to push back on social pressures that are less respectful of your diet as well. (“No, I’m going to care more about my health now to eat that… thanks anyway.”)
