If you're active, trying to eat well and doing everything "right" but your body still changes, this episode is for you. In episode four, Sarah Woodcock unpacks why shift workers so often struggle with weight — and why it has very little to do with discipline.

Sarah is clear from the start: this isn't about diets, restriction or blaming yourself. She explains how weight is shaped by far more than food and exercise — sleep, stress hormones, meal timing, recovery, routine and emotional load — and how shift work disrupts nearly all of them. She talks candidly about "fatigue eating" (grabbing whatever's available because your body is exhausted, not hungry), the pull of the snack drawer when you're running on empty, and how airport food, vending machines and 12-hour days with no proper break stack the odds against consistency.

Most of all, she shares what actually works for her: planning for when she can (not when she can't), keeping meal prep simple, making the best available choices rather than perfect ones, prioritising protein and whole foods, and letting go of the idea that one day off ruins everything. Because it's long-term consistency — not perfection in the moment — that matters.

If you've ever felt frustrated putting in effort without the results you expected, you're not alone, and it's not always about discipline.

Next episode: the mental health side of shift work — burnout and the invisible load.
