He currently weighs 63.5kg and expects to lose 3-3.5 kg by the time the Giro starts. He says he was a bit too skinny in the winter, and he was eating according to the training schedule, but they didn't take fully into account that his body was also still recovering physically from the crash. This also likely hampered his recovery.
21 year old rider, recovering from serious injury, being in offseason nad sticking to very restricted eating schedule which just means being continously on caloric deficit... What could have gone wrong?
Union of broken bones demands a lot of additional energy from a body and that's really a basic knowledge. Add to that previously mentioned some kind of miscommunication with his doctor. All of this seems just unaccepatble at this level of sport.. Being unable to treat fractured bones of professional athlete (probably the biggest cycyling's talents nowadays) properly in 21st century is ridiculous.
For me it is his team DQS that is responsible for this whole situation and Remco's delayed comeback. They should've done everything to make sure that their kid is taking appropriate actions in terms of his recovery every single day and in every possible aspect. He should've been under best possible specialists' (doctors, physiotherapists, dietitians) supervision every single day but instead we read things like "communication errors" and that they didn't take into account that human's body need extra energy when recovering from an injury...
Apart from that, this is the next lesson for cyclists that restricting calories in endurance sports like cycling should be done extremely carefully and wisely as in most cases it impairs riders' performance, leads to eating disorders or could significantly extend recovery time like in this case (such voices are heard from the peleton more and more frequently - last example of Cimolai)
