In retrospect, I think you should have taken this coach aside and explained your issues with eating disorders, etc. Or perhaps even before enrolling in the program made sure the staff understood that your weight was not open for discussion. BTW, performance on the bike is not just 'lighter is better' its about the power to mass ratio. If you are already lean and continue to lose weight you will lose muscle, which will negatively impact that ratio. You said you recently lost 30 pounds and don't feel good at this weight. So, why don't you first try to be sure you don't lose anymore weight (perhaps using your counselors that help you with your ED as a resource), and then work on gaining some muscle (here you may need coaches to guide you).

I don't think you need to stop cycling, or even racing, just be sure that whoever is involved in your training understands the whole picture.

And welcome to TE!
