3 - I’m a lifelong athlete and genuinely enjoy working out. As part of that, I have an overall fairly healthy lifestyle (enough sleep, nutritious food, no smoking, etc.).
All that said, I also have three children, and it is FAR more important to me to model body acceptance and healthy habits than to be thin. My sister and I both struggled with eating disorders when we were young, in part related to our parents’ obsession with size. Not passing that on.
