Again, great article. Well done for bringing up this topic.
There are definitely young climbers who, from my admittedly distant armchair perspective, look to be on the unhealthy side of being lean.
Do the BMC have a similar rule or guidelines to the IFSC?
It must be so hard for young competitors to get it right, particularly those with over-enthusiastic parents wanting their children to do well encouraging them.
Good comments for Dave Macleod as usual. ClimbingNutrition.com always stress that it's better to gain muscle as climber than not. More muscle more than outweighs the disadvantage of the extra weight. And you cannot gain muscle unless you're first eating a calorie surplus. It's the opposite of losing weight and the need to be in a calorie deficit.
It's also interesting to note that when you look at those at the very top of our sport, although they are typically very lean, none looks unhealthly so.
But ultimately even if there is some drop in performance due to weight gain hopefully most will appreciate that long term health always trumps climbing hard and climbing performance.
