Sarfraz Manzoor indulges in some sympathy for those that suffer anti-fat sentiment (Society does not mock skinny people, and in particular skinny men, with the same ferocity it does fat people.) but then spoils it all by using it as an incentive to get fit and thin (actually the two are not necessarily synonymous).
Of course he is failing. My advice is give up and fight for equal rights to esteem and dosh for people of girth. There is solidarity in size; let yourself go Safraz. It is more fun, cheaper and one hell of a lot easier. I guarantee you will succeed. You too can have a body like mine.
