Perhaps the most long-term consequence of having RED-S / REDs (Relative Energy Deficiency in Sport) is its effect on bone density. Sports nutrition and performance expert Rebecca McConville explains why not having stress fractures or other bone injuries is not necessarily a sign of good bone health.

[Tina]  I’m not getting any bone injuries. Does that mean my bones are fine? I haven’t got any fractures or had many other injuries, so am I okay?  

[Becca] Tough question because we don’t know what’s going on beneath the surface, and if you suspect or you have been diagnosed with RED-S, truth be told, it may be only a matter of time before some of those things start to, do come to the surface. And we praise a body that is trying really hard to be resilient, giving up its energy stores for you to be able to do the things that you love, but more than likely that is a consequence.

 So while you may not have bone stress injuries, being able to have a DEXA to look at bone density or thinking of the long-term implications. And obviously, there’s a sport that you love and we want you to be able to do that sport as long as you desire without having to spend time out for injuries, so no time like the present, even though there’s not been any injuries or consequences. And I always challenge my athletes like,  “What’s the downside of being fed? Could you feel even that more incredible when you’re doing the things that you love?” 

 [Tina]  That’s so true, and I think that’s something I realized in my time  post running professionally and recovering from RED-S, that I do find myself wondering how much faster could I have run, how much better could I have been, how much better could I have felt, had I been fueled? It really doesn’t seem like it could have done any harm; it could have only helped me. So I think that’s a really good way to put it. Thank you.
