Cravings

Cravings are a sudden, specific urge for a particular food — not “I’m hungry,” but “I need that, right now.” They’re episodic: they spike, peak, and pass, usually within 15–20 minutes whether or not you act on them. That’s different from food noise, which is the ongoing background hum of thinking about food in general, not a spike for one specific thing.

On GLP-1 medications, cravings are one of the clearest signals of how well the drug is working week to week. Most people notice a sharp drop in both frequency and intensity within the first few weeks of treatment — sweets and other “hyperpalatable” foods (chips, fast food, dessert) tend to fade first, since GLP-1 receptor agonists act on the same brain reward pathways that drive cravings, not just on stomach emptying.

Why cravings creep back

Cravings returning — especially in the days right before your next dose — is one of the most useful patterns to track. It often means the medication’s effect is wearing off before the next injection (sometimes called a tolerance dip, or a sign the dosing interval needs adjusting), not that willpower failed. This is the same mechanism behind hedonic hunger: eating driven by reward rather than actual energy need.

What’s worth logging

Three details turn “I had a craving” into something useful for a titration conversation: what it was for (something sweet, something salty, or a general urge to eat), how strong it felt, and whether you resisted or gave in. A rising trend in frequency or intensity as you approach your next dose is exactly the kind of pattern worth bringing to a prescriber.

Related terms

Cravings, food noise, and hedonic hunger describe related but distinct experiences: food noise is the ambient chatter, hedonic hunger is the reward-driven mechanism behind it, and a craving is the acute, specific spike that mechanism produces.
