Are you a doormat, or just a nice person, if you constantly make sacrifices for other people?

January’s long nights, howling winds and unending drizzle that constitute a British winter all seem to scream: stay indoors, get under a blanket and stay very still. But every year, I reach January and the same conclusion as millions of others: it’s time for change. Christmas is what does it. There’s only so much indulgence the body can take. It starts on the 24th when, if you’re lucky, work’s finished and the fridge is full. Over the next seven days, I’ll feast like a Tudor monarch, picking at carcasses, stabbing at cheese and washing it all down with a bit of port (well, someone’s got to finish it). But by New Year’s Day I’ve had enough. Meaningful, lasting change isn’t easy. The science says so. Sure, a fitness influencer will scream at you until they’re Christmas-ham-pink in the face that losing weight is JUST SIMPLE MATHS: burn more calories than you consume, and you’ll lose weight. But your genes, biology and chemistry don’t work like a calculator. There’s more to it. So we’re here to help you construct bite-sized changes that will add up to significant improvements in your health and wellbeing this year.
