GLP-1 Meal Plan: 7 Days of High-Protein Meals

An expert consensus published in 2025, written by obesity and nutrition specialists using a formal Delphi process, recommends 1.2 to 1.5 g of protein per kg of actual body weight a day during the weight-loss phase on GLP-1 therapy, and at least 0.8 g per kg once your weight is steady ^[2].

The 2025 joint advisory from four US bodies (the American College of Lifestyle Medicine, the American Society for Nutrition, the Obesity Medicine Association and The Obesity Society) says higher targets of 1.2 to 1.6 g per kg a day have been proposed during active weight loss, and adds that setting an absolute target of 80 to 120 g a day may be easier to stick to ^[1].

Two limits from the same advisory are worth knowing. Protein should not drop below 0.4 to 0.5 g per kg a day, because that can cause muscle to waste, and staying at or above 2 g per kg a day for a long time is best avoided ^[1]. If you have kidney disease, ask your own clinician for a number rather than using a general one.

Our protein calculator does this math for you, including the adjustment it uses when your BMI is 30 or above.

Because of what you lose along with the fat. A 2026 meta-analysis of 36 randomised trials, 5,316 people in total, found lean mass made up about 31% of the weight lost, with a range of 24% to 39% ^[8]. Lean mass on a body scan is not pure muscle, it includes water and organ tissue, but a quarter to two-fifths of the loss coming from somewhere other than fat is a lot. Our muscle loss calculator puts your own numbers into that range.

The medicines cut appetite hard, which is the point, but that makes protein the first thing to slip. A 2025 review of what people on GLP-1 medicines actually eat found intakes low in fiber and in several vitamins and minerals ^[11]. The authors are careful about it: "the current data are insufficient and do not allow any conclusions as to whether and to what extent the risk of micronutrient deficiencies could increase" ^[11]. So this is a reason to plan meals, not a reason to panic or to buy supplements you do not need.

Food is only half of it. The joint advisory says GLP-1 medicines should be prescribed alongside a structured exercise program with strength training at least three times a week ^[1]. Our 12-week GLP-1 workout plan is the training side of this page.

Each day comes to roughly 100 to 120 g of protein in three small meals and one snack. Nothing here takes more than 20 minutes, and half of it takes none.

The protein numbers are rounded, typical amounts for the portion sizes given. Your brand of yogurt or bread will differ a little, and that is fine. Aim for the shape of the day, not the decimals.

One day on the plan, meal by meal

Grams of protein, spread across three small meals and a snack

Breakfast · Greek yogurt, berries and seeds30 g

Lunch · Chicken wrap with spinach32 g

Snack · Cottage cheese or a shake20 g

Dinner · Salmon, rice and broccoli33 g

115 g in the day

Enough for someone around 85 kg at 1.2–1.5 g per kg

Portions behind the numbers: yogurt 170 g, cottage cheese 200 g, chicken and ground beef 120 g, salmon 140 g (31 g protein), cod 150 g, eggs 3 at breakfast, shake 1 scoop in milk. Add a vegetable or salad to every meal.

Why the day is built this way

• Three small meals plus a snack, every 3 to 4 hours. The joint advisory suggests a small breakfast and then small meals every 3 to 4 hours with enough fluid, because large meals are more likely to come back up ^[1].
• 20 to 30 g of protein in each one. A 2025 practical review puts 20 to 30 g per meal, three to four times a day, as a sensible pattern for muscle and for appetite ^[3]. Sports nutrition work lands in the same place, 20 to 40 g per serving, about every 3 to 4 hours ^[4].
• Protein first on the plate. The advisory notes that eating the protein part of a meal first makes it more likely you get enough of it before you feel full ^[1]. It is a way to hit your target, not a trick that burns fat.
• The total is what counts most. The same review is blunt that total daily protein is the main driver of body composition, and the per-meal split is a practical way to reach it ^[3].

Some weeks you will not want any of the meals above. That is expected, especially while your dose is going up. In the Zepbound trials, nausea affected 25% to 29% of people depending on the dose, against 8% on placebo, and most of it happened during dose escalation and eased over time ^[9]. With Wegovy at 2.4 mg, 44% reported nausea and 24% vomiting, against 16% and 6% on placebo ^[10].

The plan still works. Swap the meal, not the day.

What the joint advisory recommends when nausea hits: smaller, more frequent meals, and going easy on fatty and high-fiber foods for the first few days of a new dose ^[1]. Keep sipping fluids, because the dehydration that comes with vomiting and diarrhea is the part that causes real trouble. The Zepbound label notes that reported cases of acute kidney injury mostly happened in people who got dehydrated from gastrointestinal side effects ^[9].

If you cannot keep food or fluid down for more than a day or two, that is a call to your prescriber, not a meal-planning problem. The consensus also suggests a high-protein oral nutrition supplement when intake stays very low ^[2], which is a conversation to have with them.

Nothing special, just smaller. Side effects cluster in the days after a dose goes up ^{[9] [10]}, so treat the first two or three days of a new dose like the low-appetite table above:

• Keep meals small and lower in fat. Fatty food sits longer and feels worse ^[1].
• Hold off on the big fiber push. The advisory suggests going easy on high-fiber foods in the first days of treatment ^[1], then building fiber back up once things settle.
• Drink through the day rather than a lot at once, so you are not filling up on liquid at meals.
• Front-load protein. If mornings are your better window, take the bigger protein meal then and keep the evening light.

There is nothing in the Zepbound or Wegovy prescribing information that tells you what to eat ^{[9] [10]}. Anyone who says the label tells you to eat small meals is guessing. The eating advice here comes from the 2025 joint advisory and the 2025 consensus statement ^{[1] [2]}.

One shop covers the week. Quantities suit one person.

Protein

• Chicken breast or thighs, about 500 g (a little over 1 lb)
• Salmon and white fish, 2 fillets each
• Lean ground beef, 250 g (about 9 oz)
• Shrimp, 200 g (about 7 oz), and firm tofu, 1 block
• Turkey meatballs or ground turkey, 250 g (about 9 oz)
• Eggs, 12
• Greek yogurt, 1 large tub
• Cottage cheese, 2 tubs
• Milk, 2 liters (about 2 quarts)
• Canned tuna, 3 cans
• Whey, soy or pea protein powder
• Canned lentils or beans, 2 cans, and frozen edamame

Vegetables and fruit

• Spinach, salad leaves, broccoli, green beans, peppers, tomatoes, onions and garlic
• Frozen peas and frozen mixed vegetables
• Berries, bananas, peaches, a pear

Cupboard

• Potatoes, rice, couscous, pasta, rye or seeded bread, oats
• Seeds and a small bag of granola
• Hummus, feta, cheese
• Stock or broth, canned tomatoes, olive oil, herbs and spices

The same list, with tick boxes and the protein in every item, is on the printable GLP-1 grocery list.

Keep a backup shelf. Long-life protein shakes, high-protein puddings, canned fish, protein powder. These are what stand between a bad week and a week with no protein in it.

Constipation is one of the most common complaints on these medicines: 11% to 17% on Zepbound depending on dose, against 5% on placebo ^[9], and 24% on Wegovy against 11% on placebo ^[10].

• Fiber: the 2025 consensus recommends at least 25 g a day for women and 30 g for men, or 35 g for people with diabetes ^[2]. The NHS puts the adult target at 30 g a day and notes most adults get about 20 g ^[12]. The US Nutrition Facts label uses a Daily Value of 28 g ^[15]. Build up gradually rather than all at once ^[13].
• Fluids: the consensus asks for more than 2 liters (about 8 cups) a day, and says it matters even more if you are exercising, vomiting or have diarrhea ^[2]. The CDC is clear that there is no one number for everyone, as needs vary with age, sex, activity and pregnancy ^[14].
• If food is not enough: the consensus suggests a fiber supplement such as psyllium when you cannot get there from meals ^[2], and the advisory mentions magnesium, titrated to keep things regular, as one of the next options ^[1]. Both are worth raising with your prescriber.
• Move a little. The NHS lists a daily walk or run among the things that help you go more regularly ^[13].

Vegetarian

Replace the meat and fish with tofu (a 350 g block gives about 35 g), tempeh, eggs, Greek yogurt, cottage cheese, lentils, chickpeas and edamame. Two things to watch: plant meals are usually higher in fiber, which is harder work in the first days of a new dose, and portions get bigger for the same protein. A soy or pea protein shake is the simplest way to close the gap.

Dairy-free

Soy yogurt and soy milk are the closest swaps on protein. Almond and oat milk are not: they have very little. Pea or soy protein powder covers the snack, and tofu, tempeh, fish, eggs and beans cover the meals.

No-cook week

Tinned tuna or salmon, pre-cooked chicken, boiled eggs, Greek yogurt, cottage cheese, hummus, edamame, high-protein puddings and shakes. You can run the whole plan without a stove if you need to.

Over 65

Older adults hold on to muscle better with a bit more protein: about 1.2 to 1.6 g per kg a day during weight loss, and closer to 1.6 if you are also training ^[3]. Aim for the higher end of the per-meal range too, around 30 g, which is where the research on older muscle lands ^[7].

1. Get your number. Multiply your weight in kg by 1.2 and by 1.5. That range is your day ^[2]. Or use the protein calculator.
2. Divide by four. Three meals and a snack, roughly equal. A 100 g day is four servings of 25 g.
3. Adjust the plan, not the plan's shape. Short of protein? Add a shake, a pot of yogurt, or another 50 g of the meat or fish at dinner. Over? Take out the snack.
4. Check once a week, not every day. Weigh and log for three ordinary days, see where you actually land, then adjust.

A rough guide to what 20 to 30 g looks like: 100 g of cooked chicken breast (31 g), a 140 g salmon fillet (31 g), a can of tuna (25 g), 170 g of Greek yogurt (17 g), three eggs (19 g), 200 g of cottage cheese (24 g), a scoop of whey (24 g), a cup of cooked lentils (18 g), 150 g of firm tofu (15 g).

"Your body can only absorb 30 g of protein in one sitting." It absorbs all of it. The 30 g idea comes from studies of how much muscle-building the body switches on after one meal, which is not the same as absorption, and a review in the sports nutrition literature takes the claim apart directly ^[5]. Small meals suit these medicines for comfort, not because the rest is wasted.

"Eat a gram of protein per pound of body weight." That is about 2.2 g per kg. The joint advisory says to avoid staying at or above 2 g per kg a day ^[1]. The gram-per-pound rule came from bodybuilding, not from people eating 1,200 calories on a GLP-1.

"Protein first makes you lose more fat." The advisory presents protein first as a way to make sure you actually eat the protein before you are full ^[1]. It is a sequencing tip, not a fat-loss mechanism.

"Everyone needs 8 glasses of water a day." The CDC says needs vary by age, sex, activity and pregnancy, and gives no single number ^[14]. Drink through the day and more when you are exercising or unwell ^[2].

One more thing that is genuinely unsettled: how much of the per-meal split matters. A 2022 meta-analysis found the clearest gains in lean mass at 1.6 g per kg a day or more in adults under 65, and 1.2 to 1.59 in older adults ^[6], while the 2025 practical review says total daily protein is the primary determinant and per-meal timing is a way to reach it ^[3]. Get the daily total right first.
