In reply to UKC News:
I think it would be great to have a follow up video to this that explains the performance benefits of eating more (or eating well?) with a load of really convincing data to back it up. If the main goal of those that don't eat enough is improved performance, then do we need to highlight why they'll perform better with a better diet? I would assume (but I'm not dietitian or sports scientist) that it would go something along the lines of: better eating habits = better quality training and faster recovery, leading to more quality training sooner, leading to better performance.
I guess those with eating disorders may choose to add onto the end of that equation a massive crash diet to reach peak performance which is mentally hard to want to put weight back on from. One of the other issues is perhaps a need to continuously climb at your peak to satisfy sponsors (or your own drive) leading to constantly being underweight. Presumably, competition climbers periodise their weight so that they are 'heavy and healthy' when training then drop it for comps? I guess the temptation to always be at your peak means you wouldn't want to go back up to a healthy weight after the event.
I'm not sure where I'm going with this ramble really. Just empathising that its hard not to always think 'if i was a bit lighter I could pull a bit harder'. When I was 22 I was around 9 stone and didn't eat enough - I felt 'light' and it felt good. I'm now 36 and 10.5 stone. I climb harder than I ever have but its still tempting to try and diet to feel light again. I still often find myself thinking 'How unhealthy is it really to drop weight quickly for a goal as long as you've got the discipline to put it back on?'
