Everyone in my family is built like this.
My sister eats whatever she wants.
I have been fighting this since I was fourteen.
Those three sentences turn up most weeks, usually with something tired behind them. And underneath all of them is the same real question, which nobody quite asks out loud. Is this just how I am made, and have I been wasting my time?
So here it is properly, in two halves, because people tend to hear one half and miss the other.
The first half is yes. Research on twins and families has found a substantial inherited component in body weight. That is not a fringe position, and it is not something anybody should be talking you out of. If it feels as though your body responds differently than your friend’s to more or less the same life, you are not imagining it and you are not making excuses.
You may also have been told, possibly for years, that your weight is a simple matter of wanting it enough. The people saying so are working from a much simpler picture than the evidence supports. You can stop carrying that one around.
The second half is that inherited does not mean finished.
It means the same circumstances land differently on different people. Two people follow the same week and get two different outcomes, and that difference is real. But notice what it changes, because it is the opposite of what almost everybody assumes. If you inherited a harder setup, your daily habits matter more than your friend’s do. Not less. Your margin is thinner, so what happens inside it counts for more.
That is not a cheerful reframe. It is just what the picture actually implies, and it is the most useful thing on this page.
Now the other thing worth saying plainly, because there is a remarkable amount of nonsense published about this and some of it is published by hypnotists.
Hypnosis does not change your genes. It does not alter your DNA, switch anything on or off, or rewrite your biology. Anybody telling you otherwise is making it up, and that includes anybody selling hypnosis.
What hypnosis works on is the layer that is actually available to you, whatever you were born with. The automatic reaching. The eating that has nothing to do with hunger. The motivation that is deafening in January and silent by March. The voice that turns one unplanned evening into a reason to stop trying altogether.
And that layer is worth more to someone who inherited a harder setup than to someone who did not. Thin margin, remember. It is where your leverage is.
One more thing gets filed under this is just how I am, and it does not belong there either. A great many people eat more during hard stretches. A brutal year. A divorce. Grief. A move, a new baby, bad news about somebody you love. Food is the fastest comfort there is, it is right there in the kitchen at eleven at night, and it asks nothing of you.
For most people that pattern tracks the circumstances. It shows up when life gets heavy and it eases when things settle. That is a habit that formed under pressure. It is not an inherited trait and it is not a condition, and it is one of the most ordinary things human beings do.
What makes something clinical is not how much a person ate on a bad Tuesday. It is a particular pattern with particular features, identified by a licensed practitioner who has sat down with you. No website can tell you which you have, this one included.
But What About the Medications?
Fair question, and the obvious one. If a good part of this is biology, does a drug that works on the biology settle the matter?
Whether one is right for you, and for how long, is a prescribing decision, made with whoever prescribes it.
What can be said is what these medications reach and what they leave alone. They work on appetite while you are taking them. They do not touch what you reach for when you are exhausted, or what a difficult evening does to your resolve, or a twenty-year habit of eating standing up in the kitchen. A trial that followed people for a year after they stopped semaglutide found they regained roughly two thirds of the weight they had lost, and its authors concluded that ongoing treatment is required to maintain the result.
Wilding, J. P. H., Batterham, R. L., Davies, M., Van Gaal, L. F., and colleagues (2022). Weight regain and cardiometabolic effects after withdrawal of semaglutide: the STEP 1 trial extension. Diabetes, Obesity and Metabolism, 24(8), 1553 to 1564.
Please do not read that as a reason to come off anything. It is not one, and that decision is yours and your doctor’s. What it means is exactly what the rest of this page has been saying. The inherited part and the pharmacological part both sit on top of a layer of daily habit, and that layer does not sort itself out while nobody is looking. It waits.
Which makes the months when you have some room the best possible time to change it.
One last thing, since this piece has been about what is fixed and what is not. Eating disorders are real clinical conditions, they are diagnosed by licensed practitioners, and weight-focused work can make them worse rather than better. That is a different road and it needs a different kind of help. It is also not what most people mean when they say they overdid it last night.
If you would like to know how the evidence in this field actually stacks up, there is a piece on how to read hypnosis research, including the research quoted on this site.
For everybody else, the honest summary is the one in the middle of this page. You may well have inherited a harder setup. That makes the daily habits matter more, not less. And habits, unlike genes, are yours to renegotiate.
