The main argument would be that the pro is meant to already be at their ideal weight or within a few kg of it, and certainly putting out more power if they are on the heavier side of it. See Thomas De Gent as an example: challenged for the Giro, put on weight one winter, tried to lose it and maintain power, couldn't.
Comparing middling club racer to a pro who is meant to be riding for the best team with all its marginal gains, is like comparing apples to bloody beach balls
sure - they're "meant to already be", but in this case he was 5-6kg above his ideal weight, and my point is that losing 5kg is hardly "improbable" as the article states
