What to eat on tirzepatide: protein first, fluids always, and the trigger foods to skip.

Protein: roughly 1.2 to 1.6 grams per kilogram of body weight per day, spread across the day, which for most adults means 25 to 35 grams at each of three meals. On a suppressed appetite this does not happen by accident; protein has to be the first thing on the plate, because you may not get to the second thing.

Fluids: about 2 to 3 liters a day, more in Florida or Texas heat. Thirst signals fade along with hunger signals on GLP-1 medications, and dehydration is a common hidden cause of the headache, fatigue and constipation people blame on the drug.

Fiber: 25 to 30 grams a day, built up gradually. Tirzepatide slows how fast the stomach empties; fiber plus fluid is what keeps the rest of the system moving.

Smaller, more frequent. Four or five small meals beat three large ones. A full stomach that empties slowly is the mechanical cause of most nausea and reflux.

Stop at comfortable, not full. The medication delays the "full" signal; by the time you feel it you have usually overshot. Put the fork down at 80%.

Eat slowly, chew well, sit upright for 30 minutes after. Lying down after a meal is the fastest route to reflux on these medications.

Protein that goes down easily when you have no appetite: Greek yogurt, cottage cheese, eggs, fish, chicken or turkey, tofu, lentils, a plain whey or pea protein shake (choose one with under 5 grams of sugar). On the worst days, a shake and a banana is a legitimate meal.

High-fat and fried food (fast food, creamy sauces, fatty cuts) sit longest in a slowed stomach.

Very sugary food and drinks, including large fruit juices and dessert-style coffee drinks, which many people report trigger queasiness and energy crashes.

Large portions of anything, including healthy food.

Alcohol, which irritates the stomach, adds empty calories, and on a half-empty stomach hits harder than you expect.

Carbonated drinks, which add gas to an already slow stomach.

Strong smells and spicy food for some people, especially in the week after a dose increase.

Many patients find nausea peaks 24 to 72 hours after the weekly injection and for the first one to two weeks after each dose step. Practical moves: inject in the evening so the peak overlaps sleep; keep the two days after the injection bland and small (toast, rice, broth, crackers, bananas, applesauce, plain protein); ginger tea or ginger chews; cold or room-temperature food, which smells less; avoid lying flat after eating.

If a dose increase is rough, holding the current dose another two to four weeks is a normal clinical decision. At SkinnyVIP the price is the same at every dose, so there is never a financial push to move up before you are ready.

Nausea that prevents you from keeping fluids down for more than a day, vomiting more than a couple of times, inability to eat for several days, or weight dropping faster than your clinician expected are reasons to message, not to push through. Supportive prescription medication for nausea is a routine part of GLP-1 care and a licensed clinician can decide whether it is appropriate for you; at SkinnyVIP, patients can request a clinician review for nausea support, and a person answers within one hour, 7 days a week, 9am to 9pm ET. Severe or persistent abdominal pain, pain radiating to the back, vomiting that will not stop, or signs of an allergic reaction need urgent in-person care.
