"Food noise" is a popular term for the constant background of thoughts about food — what to eat next, cravings, or preoccupation with meals — that many people experience throughout the day. It isn't a formal clinical term, but it's widely used to describe one of the most commonly reported effects of GLP-1 medications: a marked quieting of these intrusive food-related thoughts, tied to the drugs' effects on appetite suppression and brain reward pathways. Researchers have started to define it more formally, linking it to how strongly people react to food cues (Hayashi et al., Nutrients, 2023 (external link)).

- Gastric emptying on a GLP-1: how much slower, how long it lasts, and what it means for gastroparesis — GLP-1 medications slow the stomach, but the trials show the effect is smaller and fades more than most people assume, especially with the long-acting weekly drugs. This guide covers how much slower, whether it lasts, how gastric emptying is measured, how it differs from gastroparesis, and why the "food ferments in your stomach" claim has no evidence behind it.
- Restarting a GLP-1 after a missed stretch: what each drug's label says about re-titration — Missed a few weeks of Wegovy, Zepbound, Ozempic, Trulicity, Saxenda, or a GLP-1 pill? Only four labels spell out when to restart at a lower dose: Wegovy injection after 2 missed weekly doses, Saxenda and Victoza after more than 3 days, and Foundayo after 7 missed daily doses. The rest are silent on long gaps. This by-drug reference separates what each label says from what's left to your prescriber, and explains why going straight back to your old dose is risky.
- Comparing the GLP-1 pills: Ozempic tablets (Rybelsus), the Wegovy pill, and Foundayo — There are now three GLP-1 pills in the US, and they aren't interchangeable: oral semaglutide for diabetes (Rybelsus, now sold as Ozempic tablets), oral semaglutide for weight (the Wegovy pill), and orforglipron (Foundayo). Here's how they compare on approval, how you take them, what the trials found, side effects, cost, and what you give up versus a weekly injection.
