I think one thing that comes to mind in terms of coaches is really helping a coach understand how every single word that comes out of their mouth is very influential in the way that the person who is on their team, or is working towards a goal with them.... Every single word matters.
For example, I have a client who had the potential for an incredible gymnastics career and because of how hard her coach was on her for the way her body looked, she made nutritional choices where she was not given advice from a nutritionist or a dietitian who was of access to the team. She ended up in hospital at the age of nine, and through the age of nine to 19, she was in and out of hospital, had hip fractures, and a lot of negative medical consequences, because of a few phrases early on.
That's just one of many examples, and I think that coaches and teachers need to understand that they either need the proper education before they give advice or to pull in a dietitian or a medical professional who can speak with the team and use the appropriate language so we aren't pushing someone towards an eating disorder or disordered eating, such as Ms. Anderson described when the individual went into that 13-year-old boy's class.
