Many women of ample proportions (like Miranda) have found comedy an effective way to deal with their feelings about their weight. Indeed, many have become rich and famous in the process as comedy is just about the only industry in the world that opens its arms to embrace 'fat' women.
I made that point in my brief reply to Nat on Page 15 by suggesting to her that, instead of losing weight a la Bigfella, she and others could avoid the hassle by becoming comedians.
Unfortunately, the message in my post must have been unclear and my post was deemed off topic which is why I'm making my point more obvious in this much-longer posting.
Brevity may be the soul of wit but the danger is that one's meaning may not always come across.
