Patient-Friendly Explanation

Working nights or rotating shifts makes it harder to control weight because it disrupts your body clock and the hormones that control hunger. Shift workers often eat at irregular times and sleep poorly, which can slow metabolism. Simple routines around meals, light exposure, and sleep can help protect your weight.

Clinical Definition

Shift work is associated with circadian misalignment, which alters leptin and ghrelin secretion, impairs glucose tolerance, reduces the thermic effect of food, and increases cravings for energy-dense foods. Meta-analyses show night-shift workers have a significantly higher risk of obesity, type 2 diabetes, and cardiovascular disease. Countermeasures include fixed meal times, bright-light exposure management, and protected sleep windows.

Why It Matters

Many patients in Singapore work shifts, and standard diet advice often fails them because it ignores the body clock. The doctors at NuLifeCare Singapore tailor meal timing and sleep routines specifically for shift workers so weight management fits their actual schedule.
