Real moms, real GLP-1 talk

The Foods I Cannot Eat Anymore

Chicken. Eggs. Coffee, for a while. Nobody warned me that specific foods would become impossible — and a trial explains more of it than I expected.

It is not that I eat less. It is that some things are just out.

Everyone tells you your appetite will drop. Fine. That happened, and it was the point.

What nobody mentioned is that certain specific foods would become genuinely impossible — not "I'd rather not", but a physical no from somewhere below conscious thought.

Mine, in order of how much I minded: chicken breast. Eggs. Coffee, for about two months. And anything creamy, which took out half of what I used to cook.

The chicken thing appears to be universal

I thought it was me until I said it out loud in a group chat and four women replied within a minute.

Plain chicken breast comes up so consistently that I now assume it. So do eggs. So does mince. There is something about lean, dense protein in a solid lump that a lot of us cannot get down anymore, which is a particularly cruel joke given that protein is the one thing everybody tells you to prioritise.

Coffee was the one that upset me most, and it did come back. Around month three it was fine again, and I have never worked out why it left or why it returned.

What the research actually says, which is more than I expected

I want to correct something, because I had assumed nobody had looked at this and I was wrong.

Food preference has been measured in a proper trial. A randomised, double-blind, placebo-controlled crossover study put 30 people on once-weekly semaglutide for twelve weeks and measured, among other things, what they wanted to eat. Alongside less hunger and fewer food cravings, there was a lower preference for high-fat foods1.

Which explains my fourth item. The creamy things did not become impossible at random — reduced preference for fatty, energy-dense food is a measured effect of the drug, not a quirk of mine.

A systematic review has since pulled together twelve randomised trials covering 445 people, looking specifically at appetite, gastric emptying, food preferences and taste2. Taste sensitivity was one of the things those trials measured.

So the honest gap is narrower than "nobody knows". What nobody has studied, as far as I can find, is why lean solid protein specifically — the chicken, the eggs, the mince — and whether the aversions reverse. I have not found anything on that, and I looked twice.

The other half is the plumbing. These drugs slow how fast your stomach empties, which is well characterised3. Dense solid food sits longest, so it is reasonable to think your body starts objecting to whatever made you uncomfortable four hours later. That part is my inference, not a finding, and I want to be clear which is which.

What I do instead

I stopped fighting it. Six weeks of trying to force down chicken achieved nothing except making dinner miserable.

I moved protein to things that are not a solid lump. Greek yoghurt, cottage cheese, protein in a drink, fish, slow-cooked things where the meat falls apart. Same target, different texture. This was the single change that helped.

I eat the protein first, while I still have room, because whatever is on the plate at the end is not getting eaten.

I stopped cooking one dinner and expecting to eat it. I cook for my family and put a small amount of something I can actually manage next to it. This felt like a defeat for about a month and now it is just how we eat.

I retry things every few weeks. Coffee came back. Cream never did. You cannot know which without checking.

The bit I would say to a friend

If a food has become impossible, you are not being fussy and you have not developed an allergy overnight. It happens to a lot of us, and the pattern is specific enough that women recognise it in each other instantly.

Do mention it if you are struggling to eat enough at all, or if the list keeps growing rather than shifting — that is different from "chicken is out" and worth a conversation with whoever prescribes for you.

I made a coffee this morning without thinking about it, which four months ago would have been unimaginable. That is the part I would want to know: some of it comes back, and you cannot tell which until it does.

Frequently asked questions

Why can I not eat chicken on a GLP-1?

Partly answered, and I had assumed wrongly that it was not. A randomised placebo-controlled crossover trial in 30 people found semaglutide produced less hunger, fewer cravings and a lower preference for high-fat foods, and a systematic review of twelve randomised trials in 445 people looked specifically at food preferences and taste. So the drug measurably shifts what you want to eat. What nobody appears to have studied is why lean solid protein specifically — chicken, eggs, mince — and whether it reverses. Delayed gastric emptying is the likely other half, since dense food sits longest.

Do food aversions go away?

Some do and some do not, and there is no research on reversal that I could find — which is the real gap here rather than the food-preference question generally. Coffee came back for me at around month three; cream never did, and given that reduced preference for high-fat food is a measured drug effect, that one may simply be the medication working. Retrying things every few weeks is the only method I have.

How do I get enough protein if meat is out?

Changing the texture rather than the target was the thing that actually worked for me — Greek yoghurt, cottage cheese, protein in a drink, fish, and slow-cooked meat that falls apart instead of sitting in a lump. I also eat the protein first, because whatever is still on the plate at the end is not getting eaten.

When is this worth mentioning to my clinician?

If you are struggling to eat enough overall, or if the list of impossible foods keeps growing rather than shifting around. That is different from a few specific things dropping off, and it is worth raising with whoever prescribes for you.
