Happy new year, readers! It’s that time again, when the tinsel and Christmas jumpers have vanished from the shops, to be replaced by a range of items designed to make you hate your body. Lycra, dumbbells, kettlebells, diet pills, skinny tea, diet books and magazines, protein powders. To turn on the TV or open Facebook is to be bombarded by images of skinny, muscled humans advertising weight loss programmes. Just like the relentless fake-happy-clappy magic-of-Christmas advertising onslaught since October, there is no escape. And this writer is having none of it.
