Apparently, Some People Only Eat When They're Hungry

I was watching the 2026 summer special of Mock the Week. Laura Lexx got handed “weight loss drugs” as an improvised topic, and her opening was roughly this: you take the injection, you stop feeling hungry, so you stop eating.

Then she said something like: this blew her mind, because apparently some people only eat when they’re hungry.

It got a laugh. It also stopped me dead for a second, because my actual reaction was: wait. People do that?

That’s the bit that nailed it for me. Not the drug joke, the bit underneath it. I don’t think I’d ever consciously separated “hungry” from “want to eat” before. They’d always just been the same sensation, arriving together so reliably that I’d never noticed they were two different things.

I can be completely full, not remotely hungry, and still want to eat something. Not need to. Want to. There’s food, I like food, so I’ll have some. That’s not hunger talking. That’s just want, dressed up as something more necessary than it is.

It took Mounjaro turning the physical side down for me to actually notice the other side was still running the whole time, separately, on its own schedule.

What’s thrown me more, though, is that I also do the exact opposite, and I only clocked it properly after noticing the first half.

Give me a BBQ. Ribs that have taken hours of prep, then a few more hours over coals, meat everywhere, me tending all of it. By the time it’s ready I’ve often completely forgotten to eat anything myself. I’m hungry, genuinely, physically hungry. And I don’t want it any more.

Same thing happens with my wife’s stew. Campfire stew, Irish stew, whatever’s slow-cooking that day, filling the house with the smell of it from mid-morning onwards. By dinner time I’m hungry. I just don’t feel like eating it. I’ll often eat next to nothing of something I’ve been smelling, and wanting, all day.

I think the smell itself does something. Enough exposure to it over enough hours and some part of my brain decides it’s already had the meal, long before my mouth has.

So hunger, it turns out, isn’t the simple fuel gauge I’d always assumed it was. Empty tank, hungry, eat, full tank. That’s not really what’s happening in me at all.

There seem to be at least three separate statements I’d been treating as one: I could eat. I want to eat. I am hungry. They often turn up together. They don’t have to. Wanting to eat shows up with a full stomach. Hunger shows up with no appetite at all, cancelled out by hours of smelling someone else’s dinner.

Mounjaro hasn’t really taught me how to eat. What it’s done is turn one of those signals down enough that the other two became visible on their own, for the first time, after a lifetime of just calling the whole tangled mess “being hungry.”

So yes, apparently, some people really do just eat when they’re hungry.

I’m only finding this out now.
