GLP-1 and the Diet Culture We Grew Up With

We were handed a scale and a story

If you are a mother in your thirties or forties, you were raised inside a very specific story about your body: that its size was a report card on your discipline. We grew up with SlimFast for breakfast, fat-free everything, magazines that scored celebrities' beach bodies, and mothers of our own who counted points at the kitchen table. The story had a moral built into it — thin was virtuous, hungry was strong, and if the weight came back, you simply had not wanted it badly enough. Now the same women are being offered a weekly injection that treats weight as a medical condition. The whiplash is real, and it deserves to be named.

The story was wrong about the mechanism

The diet culture we inherited got the biology backwards. It told us appetite was a test of character, when appetite is largely a signal — hormonal, insistent, and not especially interested in our willpower. GLP-1 medications make this visible in a way no motivational poster ever could. In a controlled study, semaglutide measurably reduced energy intake and blunted appetite and food cravings; people ate less not because they finally "tried harder," but because the drug quieted the drive to eat¹. When you can turn the volume of hunger down with a molecule, it becomes very hard to keep believing the volume was ever a moral failing.

The proof that it was never just willpower

There is an uncomfortable, clarifying piece of evidence hiding in the trial data. In STEP 1, semaglutide produced a mean weight reduction of around 15%² — but when the medication was stopped in the STEP 4 trial, much of that weight returned³. Diet culture would read the regain as backsliding, a lapse of resolve. Medicine reads it correctly: the body defended its old set point the moment the biological help was removed. The same physiology that made the weight come back is the physiology that made it so hard to lose by "eating less and moving more" in the first place. The regain is not the failure. It is the evidence.

What changes when you put down the shame

None of this means a GLP-1 is a verdict, or that every mother should be on one — it is a serious medication with real trade-offs, and it belongs in a conversation with a clinician, not an advertisement. What it means is subtler and, I think, kinder: you are allowed to stop grading yourself. The mental energy so many of us spent adjudicating our own hunger — the invisible ledger of everyone's meals — was energy the diet culture taxed and never repaid. Treating weight as biology does not make you weak. It makes you accurate. If you do decide to explore treatment, do it with eyes open about the true cost over time and read exactly how we judge providers before you trust a ranking.
