Patient-Friendly Explanation

Energy flux is the flow of energy in and out of your body. When you eat more and move more, your body is in a state of high energy flux, and research shows weight is easier to control in this state. In simple terms, staying active lets you eat more while still maintaining your weight.

Clinical Definition

Energy flux refers to the rate of energy turnover, combining high energy intake with matched high energy expenditure. High energy flux is associated with improved appetite regulation, better satiety signalling, and more sustainable weight maintenance compared with low-flux states. It is typically achieved through regular structured exercise and increased non-exercise activity.

Why It Matters

Patients who focus only on eating less often end up in a low-flux state where the body adapts and weight loss plateaus. The NuLifeCare Singapore programme emphasises raising daily activity alongside dietary changes to keep energy flux high and results sustainable.
