You’ve had a meal and feel physically full – yet thoughts about food keep circling back.
What should I eat next? Why am I still thinking about food?
If this sounds familiar, you’re not alone. Many people experience recurring thoughts about food even in the absence of physical hunger. This phenomenon is often known as “food noise.”
Food noise refers to the persistent stream of food‑related thoughts that can be difficult to quiet, even when the body has already received the nourishment it needs. It has nothing to do with willpower. Instead, it’s linked to how appetite is regulated in the brain.
On Channel 8, Dr Yew Tong Wei, Senior Consultant, Department of Endocrinology at the National University Hospital, explained that food noise occurs when the brain continues generating thoughts about eating, regardless of physical hunger cues. Some people may not feel hungry, yet delaying eating can lead to lowered mood, anxiety, or difficulty concentrating — affecting daily functioning, including focus at work.
Appetite is shaped by more than just the stomach. It involves a complex interaction between the brain, emotions, and environment – and food noise often reflects this interplay.
In the same interview, clinical psychologist Annelise Lai shared that stress, emotional strain, and major life changes can heighten preoccupation with food. During periods of stress, eating may provide emotional comfort or temporary relief.
She also noted that overly restrictive eating, such as cutting out certain food groups, can intensify food‑related thoughts. When certain foods feel “off‑limits,” they may become even more mentally prominent.
When thoughts about food feel constant or intrusive, frustration and self‑blame can follow. But understanding food noise shifts the focus from discipline to the biological and emotional factors that shape eating behaviour.
Food noise highlights that eating patterns are shaped by multiple internal cues, not personal shortcomings. Recognising these drivers is an important step towards approaching eating with greater awareness and self‑compassion.
While there is no single solution, everyday habits can influence how appetite signals are experienced and interpreted.
