If your brain runs a near-constant commentary about food — what you just ate, what you're going to eat next, whether you should have had that, what's in the fridge — you may be familiar with what's increasingly being called "food noise."
It's not greed, and it's not a lack of willpower. For many people, food noise is a genuine and exhausting experience that sits in the background of daily life, making it harder to eat intuitively, feel satisfied, and simply move on with the day.
What Exactly Is Food Noise?
Food noise refers to the intrusive, persistent mental preoccupation with food. It goes beyond normal hunger — it's the near-constant thinking about food even when you're not hungry, the difficulty stopping eating even when full, the mental negotiation around every meal, and the sense that food takes up far more headspace than it should.
It's worth noting that food noise exists on a spectrum. For some people it's a mild background hum; for others it's significantly disruptive and connected to a more complex relationship with food. If you're in the latter camp, working with a healthcare provider or registered dietitian is the most important step.
What Causes Food Noise?
Food noise can have multiple overlapping drivers:
Blood sugar instability — When blood sugar spikes and crashes (often driven by a high-sugar, low-protein diet), the brain receives urgent signals for more fuel. This can create a cycle of cravings and mental preoccupation with food that feels hard to break.
Sleep deprivation — Poor sleep disrupts the hormones that regulate hunger and fullness — ghrelin (which increases appetite) rises, while leptin (which signals fullness) falls. Many people notice significantly more food preoccupation when they haven't slept well.
Chronic dieting or restriction — A long history of restrictive eating can heighten the brain's focus on food as a survival response. The more a food is off-limits, the more mental space it tends to occupy.
Stress and cortisol — High cortisol levels increase appetite, particularly for energy-dense foods. Stress eating isn't just an emotional response — it has a physiological basis.
Gut hormone signalling — Hormones like GLP-1 and peptide YY play a role in satiety signalling. When these aren't functioning optimally, the brain may not receive clear "full" messages after eating.
Approaches Many People Find Helpful
Stabilise Blood Sugar
This is often the single most impactful change. Building meals around protein, fibre and healthy fats slows digestion and keeps blood sugar more stable — which in turn can quieten the urgent food signals the brain receives. Reducing ultra-processed foods, refined carbohydrates and added sugars is a useful starting point.
Eat Enough — Don't Skip Meals
Counter-intuitively, under-eating tends to amplify food noise, not reduce it. Ensuring you're eating regular, satisfying meals with adequate protein is one of the most effective ways to reduce preoccupation with food between meals.
Address Sleep
Given the clear hormonal link between sleep and appetite regulation, improving sleep quality is often a useful lever for people experiencing significant food noise. Consistent sleep timing, a wind-down routine, and reducing screen time before bed are all places to start.
Manage Stress
Because cortisol drives appetite and cravings, addressing chronic stress through movement, mindfulness, breathwork or other approaches you find sustainable can also make a difference to food noise over time.
A Note on Berberine
You may have seen berberine getting significant attention recently — particularly in relation to blood sugar regulation and appetite. Berberine is a plant compound with a long history of use in traditional medicine, and there is growing research interest in its role in metabolic health and gut hormone signalling.
The Patch Remedy's Thermo GL patch contains berberine alongside other ingredients designed to complement a balanced diet and healthy lifestyle. It's a topical patch worn daily — a simple, convenient format for those looking to support appetite and overall wellbeing.
