Food noise, and the food that makes it louder
This week: the intrusive, repetitive pull toward food that many people only had a name for once GLP-1 medicines made it go quiet. What it is, why the modern food environment turns it up, and the trial evidence on the drugs that turn it down.
New research
Ultra-processed food made people eat ~500 calories a day more
Hall's tightly controlled inpatient trial: same macros, very different intake — strong evidence the food environment shapes how much we eat.
SURMOUNT-1: tirzepatide and up to ~21% weight loss
The trial that pushed pharmacological weight loss into territory previously seen only with surgery.

What food noise is, why it happens, how it differs from hunger, and what quiets it — the definitive reference.
Study of the week
Why food noise happens: the neuroscience
Reward circuitry, cue reactivity, and why dieting and hyper-palatable food turn the signal up.
Clinical insight
Food noise isn't yet a formal diagnostic term — it's a patient-led description that turned out to map cleanly onto reward-system biology. That matters clinically: it reframes "constantly thinking about food" as a neurological signal rather than a character flaw, and it explains why interventions that act on reward circuitry (not just the stomach) change the experience. Background: food noise vs hunger.
Appetite science
Why does an ultra-processed diet override fullness? Energy density, softer textures, faster eating, and a weaker satiety response all stack up — the body's "enough" signals arrive too late. The mechanism is set out in why ultra-processed food doesn't satisfy and across the appetite regulation statistics.
