Too often, eating disorders in men is taken less seriously and 'novel' given the ratio between men and women suffering meaning men are the minority. Men suffering who are clearly isolated and marginalised need not have their gender questioned or jokes made about their non-existent periods.
The focus on size and shape seems to suggests eating disorder is a physical illness, which it is not. By 'calorie loading' this is simply ignoring the underlying causes of anorexia - it may put on the weight, yes. However it does little to address the key factors or triggers linked to his eating disorder.
