The GLP-1 diet is not a diet. It is a protection plan.

Search "GLP-1 diet" or "GLP1 diet" and you will find a food list. Eat this, avoid that, twenty items in each column. It is the wrong shape of answer, because a food list assumes your problem is eating too much. On a GLP-1, that problem has already been solved for you. The medication slows how fast your stomach empties and turns down the appetite signal in your brain, and most women find their intake falls sharply within the first month without trying. So an eating plan on a GLP-1 is not a restriction plan. It is a protection plan: a way of getting enough of the right things into an appetite that has become very small.

Four numbers do most of the work, and calories is not one of them. Protein: 1.2 to 1.6 grams per kilogram of your goal weight, which for most women lands somewhere between 100 and 130 grams a day. Fibre: 25 to 35 grams, because slowed digestion plus a much smaller volume of food is the precise recipe for constipation. Water: around two litres, more in heat and more if you have just raised your fibre. And two strength sessions a week, which is not food but belongs on the same list, because protein supplies the material and training supplies the reason to keep it. Everything else on the internet is commentary on these four.

Order matters far more than you would expect once the stomach only has room for a few hundred grams at a sitting. Eat protein first at every meal, before the carbohydrate and before the fat. If you can only finish half a plate, and on a GLP-1 you often can, the half you finished should be the chicken, the fish, the eggs, the Greek yoghurt, the lentils. Vegetables and fibre second. Starch last, if there is still room. Women who change nothing else about what they eat, and simply reverse the order in which they eat it, often find their daily protein total climbs without a single meal getting any bigger.

The foods that reliably make women feel worse on a GLP-1 are not the ones the internet moralises about. They are the fatty ones: fried food, creamy sauces, pastry, takeaway that arrives glistening. The reason is mechanical, not moral. Your medication already slows gastric emptying, and fat slows it further, so a heavy meal sits in a stomach that is in no hurry to move it along. That lingering fullness is what tips into nausea an hour or two later. Very large portions do the same thing by simple distension, and alcohol, fizzy drinks and very sweet drinks are the other common triggers. None of this puts those foods off limits. It makes them badly timed, and the fix is usually smaller and earlier rather than never.

Here is the part almost no one leads with. The real risk on a GLP-1 is not that you eat too much. It is that you drift into eating far too little for months without noticing, because nothing in your body is complaining. Across published trials, roughly a quarter to a third of the weight lost on a GLP-1 is lean mass rather than fat. Some of that is normal for any weight loss. A meaningful share of it is avoidable, and the two things that move it are protein and resistance training. Muscle is not vanity. It is your metabolic rate, your blood sugar control, your grip strength at seventy and the reason you can carry the shopping up two flights. A scale that drops quickly while your protein sits at 45 grams a day is not a success story. It is a body quietly spending its own reserves.

For women there is a monthly layer that generic GLP-1 diet articles never mention. Appetite is not flat across the month. Meta-analyses of energy intake find a modest rise in the luteal phase, the ten or so days before your period, on the order of ten percent compared with the follicular phase, although the effect varies considerably from woman to woman. Cravings sharpen, and nausea and fatigue can feel heavier on exactly the same dose. Then the follicular phase arrives, appetite falls away almost entirely, and that is precisely where under-eating hides. The practical move is not to fight either phase but to expect both: front-load protein in the weeks when eating is easy, and be gentler with yourself in the week when it is not.

Which leaves one practical problem. All four numbers are invisible. You cannot feel 118 grams of protein, you cannot see 30 grams of fibre, and you certainly will not remember either of them six weeks later when your prescriber asks how things have been going. That is the whole reason Steady exists. It sets your protein, water and fibre targets from your goal weight, logs them in seconds, tracks fourteen GLP-1 symptoms alongside where you are in your cycle, and turns a month into one page you can hand across a desk. The scale is the least interesting number in that picture. What you kept is the interesting one.
