Alongside the GLP-1 boom, one phrase has increasingly entered our collective vocabulary: ‘food noise’.

Originally popularised by people who experience it – and later defined by researchers in a consensus paper – the term describes persistent, intrusive thoughts about food that can be difficult to ignore. And medications such as Ozempic, Wegovy and Mounjaro have been widely praised for their ability to quieten them.

For people who experience relentless food noise, that can be a huge relief. But there’s an important distinction that can get lost in the conversation: thinking about food isn't always a bad thing.

‘Food is one of our most basic survival needs, so thinking about it throughout the day isn't inherently unhealthy,’ says Whitney Trotter, DNP, RDN, a psychiatric nurse practitioner and dietitian.

Feeling hungry before lunch and starting to think about your next meal, for example, is completely normal. Food can also be a source of pleasure – whether that's looking forward to a birthday meal or simply getting excited about what you're having for dinner.

As GLP-1 medications change how some people experience hunger and appetite, experts are warning that we need more nuance when talking about food noise.

Meet the experts: Whitney Trotter, DNP, RDN, psychiatric nurse practitioner and dietitian; Amanda Marks, LPC, LMHC, psychotherapist specialising in eating disorders; and Violeta Morris, RDN, dietitian and GLP-1 specialist.

What is food noise?

To be clear, food noise isn't simply thinking about food or occasionally experiencing cravings.

‘I think of it as persistent, repetitive thoughts about food, eating, or body-related concerns that feel difficult to ignore,’ says Marks.

Someone experiencing food noise might constantly think about what they're going to eat next, experience frequent cravings or feel preoccupied with food throughout the day.

As for why some people experience it more than others, research suggests food noise may be influenced by a combination of biological, dietary, psychological, emotional and environmental factors.

‘Food-related thoughts are regulated by an incredibly sophisticated network involving hormones, metabolism, learning, and the brain's reward system,’ says Trotter.

How do GLP-1s affect food noise?

That's where GLP-1 medications come in.

GLP-1 medications mimic hormones involved in appetite regulation and can affect the brain pathways involved in hunger and fullness. A 2026 narrative review suggested they could potentially regulate brain processes involved in obsessive food thoughts, although more rigorous research is needed to establish exactly how this works.

One 2026 study involving a mostly white female population found an association between taking a GLP-1 medication and a reduction of more than 50% in the self-reported frequency, intrusiveness and disruption caused by food noise over approximately four months.

For someone whose thoughts about food have become overwhelming or are interfering with everyday life, that could clearly be beneficial.

But experts say the reason you're thinking about food matters.

When reducing food noise isn't necessarily a good thing

In other areas of medicine, persistent thoughts about food can be understood as a biological response to restriction or undernutrition – particularly in eating disorder treatment.

It's long been documented that food deprivation can lead to intrusive and obsessive thoughts about eating. The landmark Minnesota Starvation Experiment, which studied the effects of severe food restriction in healthy men during the Second World War, documented food preoccupation, obsessive thoughts, rigid thinking and reduced concentration.

When you're undereating – whether intentionally through dieting or unintentionally because of illness – your body can respond by making food increasingly difficult to ignore.

‘When someone describes constant food thoughts, my first clinical question is never “how do we stop this?”’ says Trotter. ‘It’s “what is this telling us about what this person's body needs?”’

‘When someone describes constant food thoughts, my first clinical question is never “how do we stop this?” It’s “what is this telling us about what this person's body needs?”’

That's why some eating disorder specialists are questioning the assumption that all food noise should be eliminated.

‘My concern is that we've started to pathologise something that is often a completely normal biological experience,’ says Trotter.

Food thoughts can be triggered by inadequate nutrition, but also by factors including sleep deprivation, stress and restricting foods you genuinely enjoy. Sometimes, thinking repeatedly about food may simply be your body's way of telling you that it needs more energy.

GLP-1s can make hunger cues harder to recognise

Food thoughts aren't only about physical hunger, either. Looking forward to meals and enjoying food can be part of a healthy relationship with eating.

‘This is where the nuance of food noise needs to be carefully explored,’ says Marks.

For people taking GLP-1 medications, significantly reduced appetite can make interpreting the body's usual hunger cues more difficult.

‘It could make it more difficult to recognise when the body is being undernourished,’ Trotter explains.

If appetite and food thoughts are significantly reduced by medication, she says healthcare professionals may need to pay particular attention to other indicators of nutritional and physical health, including blood test results, weight trends, food and nutrient intake, mood and menstrual health.

What if you have a history of disordered eating?

This becomes particularly important for anyone who has experienced an eating disorder or disordered eating.

A 2026 study examining GLP-1 medication use among people with eating disorders found that nearly a quarter of participants reported currently using a GLP-1, while almost a third said they had used one at some point.

Researchers also found that 10% of participants reported misusing the medication, raising concerns that GLP-1s could potentially be used to facilitate food restriction and weight loss among people with eating disorders.

For someone with a history of restrictive eating, chronic dieting or an active eating disorder, Trotter cautions that dramatically suppressing food noise could pose risks to both physical and psychological health.

Someone may assume they're doing better because they're no longer thinking about food, while a suppressed appetite could make it easier to undereat. Nutritional deficiencies can contribute to loss of lean muscle mass, fatigue, hormonal changes, impaired cognitive function and poorer bone health.

In other words, GLP-1s can potentially complicate two important aims of eating disorder recovery: reconnecting with hunger cues and getting adequate nutrition.

7 questions to ask yourself about food noise

Whether you're taking a GLP-1, considering one or simply experiencing changes in your thoughts around food, it can be difficult to separate what's normal from what's potentially problematic.

These questions, developed with Trotter, Marks and Violeta Morris, RDN, a dietitian and GLP-1 specialist, may help:

  • What’s my relationship with food like?
  • How has it changed over the years? Has it become more or less stressful or rigid?
  • How clearly can I tell when I’m hungry or full?
  • Am I able to recognise other signals from my body, such as hunger and thirst?
  • Do I experience food noise? What does it feel like, and when does it tend to appear?
  • Do I experience fatigue, headaches, brain fog, sleep disruption, dizziness, mood swings or low blood sugar, which could indicate that I'm not meeting my energy or nutrient needs?
  • Are my thoughts about food interfering with my life?

Take some time to consider your answers without immediately labelling food thoughts as either ‘good’ or ‘bad’.

‘Let’s remember not to jump to extremes and to instead explore the nuance of food noise because it isn’t inherently good or bad,’ says Marks.

If your food thoughts feel distressing, overwhelming or are disrupting everyday life – or you're concerned about your relationship with food while taking a GLP-1 – speak to a healthcare professional who can help establish what's driving them and what support you need.

The bottom line

For some people, reducing food noise can be genuinely life-changing, particularly when thoughts about food have become relentless and disruptive.

But not every thought about food is ‘food noise’ – and wanting lunch when you're hungry, looking forward to dinner or enjoying food isn't something that needs to be fixed.

Sometimes, persistent thoughts about food can also be a sign that your body isn't getting enough energy. That's particularly important for people taking appetite-suppressing medications or those with a history of restrictive eating or eating disorders.

The goal, then, shouldn't necessarily be to never think about food. It's to understand what those thoughts are telling you – and whether they're supporting or interfering with your physical and mental health.
