NEW DELHI : You’ve just finished lunch. You’re physically full, yet your mind is already wandering towards the biscuit tin, leftover dessert or a packet of chips. If this sounds familiar, you’re not alone. The phenomenon, often referred to as “food noise,” is gaining attention among obesity specialists as more people realise that constant thoughts about food aren’t always linked to true hunger.
Dr Neha Shah, Bariatric and Metabolic Surgeon, Chief Obesity Specialist and co-founder, The Good Weight, one of the most common complaints she hears from patients is what she calls the “2 pm problem.”
“You’ve eaten lunch, you’re not actually hungry, and yet there’s this nagging voice cataloguing everything in the pantry. That’s food noise, the persistent mental chatter about eating that has nothing to do with actual physical need,” adds Dr Shah.
She emphasises that this isn’t simply a matter of poor willpower. “It’s biology. And honestly, I think we’ve spent years blaming patients for something their hormones were doing to them all along.”
The Hormone Problem
Dr Shah explains that hormones play a much larger role in regulating appetite than most people realise.
Ghrelin, often referred to as the “hunger hormone,” naturally rises before meals and should fall after eating. Leptin, meanwhile, signals to the brain that the body has had enough food.
“It sounds simple on paper,” says Dr Shah. “But in many of my patients, especially those who’ve spent years dieting on and off, that entire signalling system begins to break down.”
She notes that ghrelin may remain elevated for longer than normal, while leptin resistance gradually develops, making it harder for the brain to recognise fullness.
“The brain simply stops receiving the ‘I’ve had enough’ signal with any clarity,” she explains.
According to Dr Shah, insulin resistance further complicates the picture by causing energy crashes between meals that can feel like genuine hunger, even shortly after eating a substantial meal.
The Food Pattern Problem
What people eat and when they eat, also has a significant impact on food noise. Dr Shah points out that diets high in refined carbohydrates and ultra-processed snacks often create rapid spikes in blood sugar, followed by equally sharp crashes. “Each crash is interpreted by the brain as an emergency,” she says.
She frequently sees patients skipping breakfast, only to find themselves reaching for biscuits or fried snacks by mid-morning. “It’s not indiscipline,” Dr Shah explains. “Their blood sugar has genuinely dropped.”
Irregular meal timings, long workdays and unpredictable schedules only make matters worse by preventing hunger hormones from settling into a predictable rhythm.
The Sleep and Stress Problem
Sleep deprivation and chronic stress are often overlooked contributors to constant hunger.
According to Dr Shah, even a single night of inadequate sleep can increase ghrelin while lowering leptin, making people feel significantly hungrier the following day regardless of how much they ate.
“Add cortisol from chronic stress into the equation, and you’ve created a hormonal environment that’s almost designed to produce food noise,” she says.
She recalls seeing patients who believed they simply lacked self-control, only to discover that weeks of sleeping four or five hours a night were largely driving their cravings.
What Actually Helps?
Rather than focusing solely on eating less, Dr. Shah recommends improving meal quality. “Protein comes first,” she says.
Adding eggs to breakfast instead of relying only on toast, or pairing rice with a generous serving of dal, helps slow digestion and reduces rapid fluctuations in blood sugar.
“Protein and fibre slow stomach emptying, preventing the sharp glucose spikes and the crashes that follow.” She shares that one patient added sprouts to her breakfast for just a week before noticing that her usual mid-morning cravings had almost disappeared. Meal timing matters too.
“You don’t have to eat at exactly the same minute every day,” Dr. Shah says, “but keeping meals within a fairly consistent window helps because ghrelin follows an internal clock.”
Sleep, she adds, is another powerful yet often underestimated intervention.
“Even two additional hours of sleep over a few consecutive nights can measurably improve ghrelin and leptin levels.”
For some individuals, particularly those living with insulin resistance or a long history of repeated dieting, lifestyle changes alone may not completely quiet food noise.
In such cases, Dr Shah discusses GLP-1 receptor agonists, which work directly on appetite regulation rather than relying solely on willpower.
Listen to the Noise
Ultimately, Dr Shah encourages people to stop blaming themselves for constant cravings and instead investigate their underlying cause.
“Don’t just try to push through the noise,” she says. “Ask where it’s coming from first. Sometimes it isn’t in the kitchen at all, it’s in your bloodwork, your sleep diary or a source of stress that hasn’t yet been recognised.”
Understanding food noise as a biological response rather than a personal failing is the first step towards building healthier, more sustainable eating habits.
