Hydration: The Easiest Win
The Academy of Nutrition and Dietetics suggests 80 ounces of water per day on a GLP-1. Skipping water causes constipation, headaches, and worse nausea. Add an electrolyte powder once a day (low or no sugar). Sip from a 24-ounce water bottle. Drink it 4 times across the day.

Frequently Asked Questions
What is the Zepbound starting dose?
Per the FDA label for Zepbound, the starting dose is 2.5 mg once weekly by subcutaneous injection. You stay at 2.5 mg for 4 weeks. The Eli Lilly patient guide calls this the initiation dose, not a treatment dose. Most people see small appetite changes in week 1, with bigger effects after the dose steps up to 5 mg, 7.5 mg, and beyond.
How much will I eat in week 1 of Zepbound?
Most users still feel close-to-normal hunger in week 1 at 2.5 mg. Some notice they fill up faster. The Eli Lilly patient guide does not set a calorie target. The Academy of Nutrition and Dietetics suggests a moderate deficit of 500 to 750 calories per day to start, plus a protein floor of 1.2 to 1.6 grams per kilogram of body weight. For a 200-pound (91 kg) adult, that is roughly 1,500 to 1,800 calories and 110 to 145 grams of protein.
Will I feel nauseous on Zepbound 2.5 mg?
Some users do, some do not. The Zepbound FDA label reports nausea in 12 to 18 percent of users at the 2.5 mg dose. That is lower than higher doses. The biggest triggers are large meals, high-fat foods, and skipping water. The Lilly patient guide suggests small meals and avoiding rich foods to ease in.
What should I eat the day I take my Zepbound shot?
Stick to bland, easy-to-digest foods on shot day. The Lilly patient guide says nausea can peak in the 24 to 48 hours after injection. Pick lean protein (chicken, fish, eggs), simple carbs (rice, oatmeal, toast), and clear fluids. Skip greasy or very spicy foods until you know how your body responds.
How much protein do I need on Zepbound week 1?
The International Society of Sports Nutrition and the Academy of Nutrition and Dietetics both suggest 1.2 to 1.6 grams of protein per kilogram of body weight per day during weight loss. This protects muscle as fat drops. For a 180-pound (82 kg) adult, that is 98 to 131 grams of protein per day. Split it across 4 to 5 meals.
Can I follow a low-carb plan on Zepbound week 1?
You can, but simple carbs help ease nausea in week 1. The Lilly patient guide suggests balanced meals while your body adjusts. A few servings of rice, oats, fruit, or sweet potato per day support energy without spiking blood sugar. Once you settle in at 2.5 mg with no GI issues, you can shift toward lower-carb if you prefer.
Should I weigh myself on week 1 of Zepbound?
Weigh once at the start and once at the end of week 1. Most users lose 1 to 3 pounds in week 1 at 2.5 mg. Some lose 0. A few lose more from water shifts. None of this predicts your full results. The SURMOUNT-1 trial showed average tirzepatide weight loss of about 22.5 percent at 72 weeks for the 15 mg dose, but that takes many months and dose increases.
What if I miss my first Zepbound shot?
The Eli Lilly patient guide gives clear instructions. If you remember within 4 days, take it as soon as you can. If more than 4 days have passed, skip that dose and take your next one on your normal day. Never take two doses close together. Talk to your prescriber if you miss multiple shots.
