Dr Ezekiel J Emanuel, a former Obamacare adviser, has deceptively simple advice for living a healthy life

Being healthy shouldn’t feel this complicated. Yet every week brings a new wellness fixation, from “fibermaxxing” to “zone 2 training”, creatine and cortisol-hacking.

Between prescriptive plans, complex science and often contradictory advice, it can seem like being healthy is a full-time job – or a hopeless cause.

It’s neither, argues Dr Ezekiel J Emanuel, a leading public-health physician, a professor at the University of Pennsylvania and former adviser to the Obama administration. In his new book, Eat Your Ice Cream: Six Simple Rules for a Long and Healthy Life, Emanuel dismantles the “wellness industrial complex” in favour of a few basic, sustainable principles.

“The way I like to think about it is we both make it too complicated – and we also make it too simple,” he says. Here is Emanuel’s expert pick of the wellness advice you can afford to leave behind in 2025 – and what to focus on instead.
