What is food noise?
Persistent, intrusive thoughts about food between meals. It is tied to appetite hormones, GLP-1 among them, and it quiets when those signals are stronger and last longer.
A definition
Food noise is the running commentary about eating that plays when you are not hungry. What is in the fridge. Whether to have the second one. How long until lunch. It is not the same as hunger, which is a body signal that comes and goes. Food noise is a thought loop, and for many people it never fully switches off.
Why it got a name
The term spread when people on prescription GLP-1 medications began describing the same thing: the chatter stopped. Researchers took notice, and food noise is now studied as its own phenomenon, with questionnaires built to score it. What those medications revealed is that the loop is not a character flaw. It is a signal problem, and signals can be changed.
What drives it
- Appetite hormones. Ghrelin turns the volume up. GLP-1, leptin and a handful of others turn it down. When the quieting signals are weak or short-lived, the noise fills the gap.
- Blood sugar swings. A fast rise and fall after a sweet drink or refined snack is a reliable trigger.
- Cues. Food within sight, food in adverts, food on a schedule you did not choose.
- Short sleep. One bad night is enough to raise next-day cravings in most people.
- Restriction. Skipping meals tends to make the noise louder, not quieter, which is why strict diets are so hard to hold.
How GLP-1 fits
GLP-1 is released by the gut when you eat. It tells the brain the meal is enough and slows the stomach so the message lasts. It is cleared within minutes by an enzyme called DPP-4. More active GLP-1, for longer, means a stronger and longer quiet after eating. That is the lever prescription medications pull, at pharmacological strength. It is also the lever the body can pull on its own, at its own scale.
What quiets it
- Protein and fiber at every meal, breakfast included.
- Regular meals, so the body stops bracing for a gap.
- Fewer blood-sugar spikes. Water or an unsweetened drink instead of a sweet one.
- Sleep, protected.
- Raising active GLP-1. In a 16-week randomized, placebo-controlled trial, 300 mg a day of CQR-300 raised active GLP-1 321% and lowered DPP-4 activity 17.8%. Participants ate 17.5% fewer calories a day.¹ The trial measured energy intake, not a food-noise score. Eating less over four months is the closest a study gets to measuring a quieter appetite.
Calla puts 300 mg of CQR-300, which we call Micro GLP-1, in a daily energy drink. Less food noise between meals is the point. More on raising GLP-1 naturally.
When to talk to someone
If thoughts about food are distressing, if they come with guilt, or if they run alongside restricting, bingeing or purging, that is beyond what any drink addresses. A physician or a registered dietitian is the right next conversation, and it is a common one to have.
