Ozempic Diet Plan: What to Eat in Your *FIRST 30 DAYS* to lose weight on a GLP-1
Our summary
Maria Lucey, a registered dietitian, gives a first-30-days plan for people starting a GLP-1 medication such as Ozempic, Wegovy or Mounjaro. She says the first week matters most. She advises against a large last meal the night before the first injection, because the drugs slow stomach emptying and a heavy meal could cause nausea, cramps or vomiting. She suggests stocking the house with healthy food, injecting in the morning, and not rushing to a higher dose, since the medications are designed to be increased slowly.

What else the video covers
On eating, she says calories should stay at a minimum of 1,200 for women (up to 1,500 if they exercise) and 1,500 for men (up to 1,800 if more active), warning that eating less risks metabolic adaptation. She describes a plate of half vegetables, a quarter protein and a quarter starchy carbohydrate. She recommends 1.6 g of protein per kg of target body weight daily, strength training from day one, three meals a day, about 30 g of fiber, 30 different plant foods a week, at least eight glasses of fluid, and regular walking. She also suggests liquid nutrition for three or four days at most if solid food is hard.
She then covers side effects. She suggests avoiding processed, fatty and spicy foods, excess caffeine, carbonated drinks, straws and alcohol. For constipation she names flax seeds and two kiwi fruits a day, and for nausea dry, cold and bland foods. She closes by saying weight loss often slows after a fast start, that the medications do not fix emotional eating, and that the time on them is a chance to build habits that last.

Questions this video answers
What should you eat in the first week on Ozempic or Wegovy?
Maria says to aim for a balanced plate of half vegetables, a quarter protein and a quarter starchy carbohydrate, with protein at least three times a day. She also suggests three meals a day rather than one large meal, which she says raises the risk of nausea and indigestion.
How much protein do you need on a GLP-1 medication?
She recommends 1.6 g of protein per kg of body weight each day, based on your ideal or target weight rather than current weight. She says this is probably at least 80 to 100 g for most people, and pairs it with strength training to help preserve muscle.
How can you ease constipation and nausea on a GLP-1?
For constipation, Maria suggests flax seeds, starting at one teaspoon a day and building to 1 to 2 tablespoons with extra fluid, and two kiwi fruits a day. For nausea, she says dry, cold and bland foods tend to help, and that skipping meals can make nausea worse.

- The GLP-1 diet: what to eat on Ozempic, Wegovy or Zepbound, and what to limit, from the 2025 joint advisory
There is no special GLP-1 diet, but there is now a consensus on how to eat on one. A 2025 advisory from four medical societies says to build meals around fruits, vegetables, whole grains, legumes, lean proteins, nuts and seeds; limit refined carbohydrates, sugary drinks, red and processed meats, fast food and ultra-processed snacks; eat small regular meals; drink enough fluids; and put protein first, because appetite drops and muscle is at risk. During dose increases, smaller meals and avoiding fatty or high-fibre foods ease nausea.
- Ozempic dosage chart: 0.25 mg to 2 mg, every pen, the missed-dose rule, and what each dose costs
Ozempic starts at 0.25 mg once a week for four weeks, then goes to 0.5 mg. If more blood sugar control is needed after at least four weeks, it can go to 1 mg, and after four more weeks to 2 mg, the maximum. Paying cash through NovoCare it is $199 for each of the first two months, then $349 a month up to 1 mg and $499 at 2 mg.
- How long do Ozempic, Wegovy and Zepbound take to work? The label calendar and the trial timepoints
GLP-1s act from the first dose, but the labels start low on purpose and step up every 4 weeks, so most people do not reach a full dose for 3 to 5 months. Each dose reaches steady levels in the blood after about 4 to 5 weeks. In the trials, people averaged 10.6% weight loss after 20 weeks of Wegovy's escalation and 20.9% after 36 weeks of Zepbound, with the full trial results at 68 to 72 weeks. For type 2 diabetes, Ozempic's A1C results were measured at week 30.
