GLP-1 Diet Plan: What to Eat on Semaglutide or Tirzepatide

There is no single GLP1 diet plan: for people taking a GLP-1 medication, the usual advice is balanced, minimally processed meals with enough protein, eaten in smaller portions.^1,2,3

Semaglutide and tirzepatide belong to a group of drugs called GLP-1 receptor agonists, medicines that curb appetite.^4,5 Smaller, more frequent meals, less greasy food and less alcohol may ease their stomach side effects, and protein with resistance training may help preserve muscle.^1,3,6 Evidence on the best way to eat during this treatment is still limited, even though dietary advice is commonly given.⁷

What Is a GLP-1 Medication?

Glucagon-like peptide 1 (GLP-1) medications are man-made hormones used to treat type 2 diabetes, and some are also used for weight loss in people with obesity.⁵

They cause many of the same actions as natural hormones, and the higher the dose, the stronger the effect.⁵ Tirzepatide acts on two receptors, glucose-dependent insulinotropic polypeptide (GIP) and GLP-1.⁸

Why Do You Eat Less on a GLP-1 Medication?

GLP-1 medications can reduce appetite and food cravings and slow digestion, so you may feel fuller for longer.⁵

A trial in 72 adults with obesity compared weekly semaglutide, raised to 2.4 mg, with a placebo for 20 weeks.⁹ At a test meal where people could eat as much as they wanted, those on semaglutide ate 35% fewer calories than those on placebo.⁹ In these adults with obesity, semaglutide also reduced appetite and food cravings and improved control of eating compared with placebo.⁹

A 60-week trial randomly assigned 120 adults with overweight or obesity to semaglutide 2.4 mg or placebo.¹⁰ At the test meal, the semaglutide group cut its intake from the start of the trial by 291.9 more calories than the placebo group at week 20, 240.2 more at week 40 and 269.5 more at week 60.¹⁰

In the 60-week trial, though, appetite ratings did not differ significantly between the groups at weeks 40 or 60.¹⁰

A Cleveland Clinic guide says delayed stomach emptying is at its worst in the first three to four weeks on a GLP-1 medication, when people often have their most significant side effects.³ The semaglutide trial in 72 adults with obesity found no sign of delayed emptying at week 20, though it measured emptying only indirectly.⁹

What Should You Eat While Taking a GLP-1 Medication?

No specific GLP-1 diet has been established, and the usual advice is balanced meals built on minimally processed foods, protein, fruit, vegetables and whole grains.^1,2,11

Typical choices include leafy greens, apples and tomatoes; lean proteins such as fish, chicken, tofu and beans; whole grains such as oats, quinoa and farro; and healthy fats.^11,1 A tirzepatide label says the medicine is meant to be used together with a reduced-calorie diet and more physical activity.⁸

A review of sixteen randomized trials in 7096 adults taking these medicines with diet or lifestyle advice, most at low risk of bias, found that evidence on the best way to eat remains limited.⁷ None of those trials reported clinically relevant nutritional deficiencies.⁷

Even so, Mayo Clinic Press notes that eating less overall can mean missing some vitamins and minerals, and suggests a basic multivitamin may be useful in the long term.¹

How Much Protein Do You Need on a GLP-1 Medication?

No daily amount of protein has been settled for people on a GLP-1 medication, and the amounts suggested differ from one source to the next.^7,1,12,13

• Mayo Clinic Press: a clinician there uses a target of one and a half grams of protein per kilogram of ideal body weight a day for patients on a GLP-1 medication.¹ Having treated hundreds of patients on these medicines, the same clinician calls 80 to 100 grams a day probably a safe bet.¹
• A Cleveland Clinic article: a general guideline of between 0.8 and 1 gram of protein per kilogram of body weight a day.¹² It adds that age, weight, level of activity, overall health and whether you are intentionally losing weight might change how much protein you need.¹²
• Per meal: Mayo Clinic Press says most healthy adults benefit from 20 to 30 grams of protein per meal, spread through the day rather than mostly in one meal.¹³

Mayo Clinic Press notes that dairy, meat, eggs, fish, poultry and soy foods provide all nine essential amino acids, while many plant foods may be lower in one or more of them.¹³

If you have chronic kidney disease, agree on any protein target with your provider first, as your needs may differ.¹⁴

Do You Lose Muscle on a GLP-1 Medication?

Some of the weight lost on a GLP-1 medication is lean mass, generally in proportion to the weight lost, though that evidence is of low certainty.^7,15 Resistance training with enough protein may help preserve muscle.⁶ Lean mass includes muscle and other body tissues that are not fat.

In a body-scan substudy of the SURMOUNT-1 tirzepatide trial with 160 participants, about 75% of the weight lost by week 72 was fat and 25% was lean mass.¹⁶ That split was about the same with tirzepatide and with placebo.¹⁶

A review of twenty randomized trials in adults with overweight or obesity found lean mass made up 35.2% of weight lost with semaglutide and 25.4% with tirzepatide.⁶ In the same review, lean mass made up 26.2% of weight lost in lifestyle programs, broadly comparable with the medicines as a group.⁶ The share was lowest, 17.5%, when lifestyle programs included resistance training.⁶

A review of 35 studies, median length 26 weeks and median size 78 people, found that a median 28.3% of the weight lost on these medicines was put down to loss of muscle.¹⁷ Only 42.9% of its studies were at low risk of bias.¹⁷

A meta-analysis of 60 studies, 46 of them randomized trials, linked these medicines to some loss of lean mass, on low-certainty evidence, with the changes largely related to weight loss.¹⁵ It found no significant effect on bone density or fractures when its models included the most adjusted effect size.¹⁵

What Does a Day of Eating Look Like on a GLP-1 Medication?

Smaller, more frequent meals, with protein spread across them rather than saved for one, might work well for a day of eating on a GLP-1 medication.^1,3,13

A Cleveland Clinic guide explains that smaller, more frequent meals give the stomach more time to digest in between, which can help keep digestive problems away.³

A Mayo Clinic Press article adds that such meals may help you meet protein and fiber needs without the discomfort of a meal that is too large.¹ Mayo Clinic Press also suggests planning to halve your meals, choosing less greasy food and not eating out at first.¹

Here is one sample day from Telezen MD; it is an example, not a prescribed menu.

• Breakfast: two scrambled eggs with a slice of whole-grain toast and half an avocado.
• Lunch: 4 oz grilled chicken with a small portion of brown rice and steamed broccoli.
• Dinner: soft baked salmon with roasted sweet potato and cooked zucchini.
• Swaps: Greek yogurt with berries and chia seeds; cottage cheese with cucumber and whole-grain crackers; or a tofu stir-fry with brown rice and cooked bok choy.

Which Foods Should You Limit on a GLP-1 Medication?

High-fat, spicy and sugary foods, refined carbohydrates and alcohol can make side effects worse, so it may help to limit them.^11,3,1

On these medicines food stays in the stomach longer, and fat takes longer to digest, so a high-fat meal can sit there and cause nausea or vomiting.^11,2 A Cleveland Clinic guide notes that every body is different, so finding your trigger foods can take time; in general, it suggests limiting or avoiding these.^11,3

• Added sugar, such as juice, soda, candy and desserts.^11,3
• Refined carbohydrates, such as white bread and white rice.^11,3
• Processed and ultra-processed foods, such as packaged snacks.^11,3
• High-fat foods, such as pizza and fried chicken.^11,3
• Spicy foods, such as hot sauce and hot peppers.^11,3

Mayo Clinic Press also suggests limiting alcohol to help reduce side effects.¹

What Can Ease Nausea, Constipation and Other Stomach Side Effects?

Unsweetened ginger or peppermint tea, staying upright after meals, enough water and soft, bland foods may ease particular stomach side effects in people on a GLP-1 medication.^3,1

A review of sixteen trials found these medicines consistently increased nausea, diarrhea, constipation and vomiting, often more at higher doses, even alongside diet or lifestyle advice.⁷

In a meta-analysis of thirteen trials in people with obesity but without diabetes, stomach side effects were 1.86 times as common with semaglutide or tirzepatide as with placebo.¹⁸ The figure was 2.94 for tirzepatide and 1.68 for semaglutide.¹⁸ Most cases were mild.¹⁸

A Cleveland Clinic guide says people often have their worst side effects in the first three to four weeks on a GLP-1 medication.³

• Upset stomach: the same guide says ginger or peppermint tea may help, but without sweeteners, which can make things worse.³
• Nausea after meals: the guide also suggests staying upright for 30 minutes after eating, since lying down can make nausea worse.³
• Constipation: drinking enough water helps soften stool.^3,1
• Fiber: Mayo Clinic Press notes that eating less can mean eating less fiber, but the Cleveland Clinic guide says that if you already feel bloated or full, adding more fiber may be too much.^1,3
• Diarrhea: the guide suggests water and good sources of electrolytes, plus soft, bland, low-fiber foods.³

Risks and Who Should Check With a Provider First

Dehydration from vomiting or diarrhea, and eating or drinking too little, are risks to watch for while you take a GLP-1 medication.^8,1

Reports gathered after these medicines went on the market describe acute kidney injury, sometimes needing dialysis, in people taking GLP-1 medicines.⁸ Most of those cases occurred in people who became dehydrated after nausea, vomiting or diarrhea.⁸

Mayo Clinic Press notes that a reduced appetite can make it easy to under-eat or under-hydrate.¹ A clinician it quotes says they might give some patients minimums for fluids and protein, and a calorie minimum for those at risk of hardly eating at all.¹

Mayo Clinic Press quotes a clinician who puts enough fluid at the top of the daily list for patients on these medicines: two to three liters a day.¹

Call your provider if nausea, vomiting, diarrhea, stomach pain or constipation is severe or does not go away.^19,8 A tirzepatide label also tells patients to report signs of kidney injury promptly.⁸

Tell your provider before starting, or before changing how you eat, if any of these apply to you: some change whether the medicine suits you or how it is used.

• You have severe gastroparesis: a semaglutide label says the medicine is not recommended for people with this condition.²⁰ Gastroparesis is a disorder that slows or stops the movement of food from the stomach to the small intestine.
• You take insulin or a sulfonylurea: a tirzepatide label advises considering a lower dose of these diabetes medicines at the start, to reduce the risk of low blood sugar.⁸
• You are pregnant or breastfeeding: MedlinePlus advises telling your provider.¹⁹ The same tirzepatide label warns the medicine may harm an unborn baby and says to stop it once pregnancy is recognized.⁸
• You cannot keep fluids down: MedlinePlus’s semaglutide page advises telling your provider about recent vomiting, diarrhea or nausea, or not being able to drink, which may cause dehydration.¹⁹
• You have chronic kidney disease: the National Institute of Diabetes and Digestive and Kidney Diseases says some people with it may need moderate amounts of protein, while too little may lead to malnutrition.¹⁴
• You have had an eating disorder: a review of open questions about these medicines and eating disorders warns that the mechanisms that curb appetite may also reinforce restrictive eating and relapse in vulnerable people.²¹ Its authors propose routine eating-disorder screening before and during treatment.²¹
• You are a child or teenager: that tirzepatide label says the medicine’s safety and effectiveness have not been established in children and teenagers.⁸

Does This Advice Apply to Compounded Semaglutide and Tirzepatide?

Do not assume the trial results in this article, such as how much less people ate or how much lean mass they lost, apply to a compounded medicine. Whether the general eating advice changes for a compounded medicine is a question to ask your provider.

Compounded GLP-1 medicines are not approved by the Food and Drug Administration (FDA), which does not review them for safety, effectiveness or quality before they are sold.^4,22 Compounding is generally a practice in which a licensed pharmacist or physician combines, mixes or alters a drug’s ingredients to create a medication tailored to the needs of an individual patient.

The FDA warns that turning to unapproved versions of GLP-1 drugs, including semaglutide and tirzepatide, for weight loss can be risky because they do not go through that review.⁴ It also says compounded drugs should be used only for patients whose medical needs an approved drug cannot meet.⁴

What Does Telezen MD Include to Help You Eat on a GLP-1 Medication?

Every Telezen MD GLP-1 plan includes the GLP-1 Nutrition Protocol and the Lose It for Life course at no extra cost, as the plan page lists.

The GLP-1 Nutrition Protocol is a proprietary program, available only to Telezen MD patients, that teaches how to eat on a GLP-1 medication. It has 7 modules and 26 lessons, covering:

• Protein and muscle preservation.
• Fiber and hydration.
• The GLP-1 Plate Framework, which builds every meal from four parts: protein, a carb, a vegetable and a fat.
• Meal templates for breakfast, lunch, dinner and snacks.
• Nausea and low-appetite troubleshooting.
• Eating out.
• Eating for life after GLP-1 treatment ends.

Lose It for Life is a self-paced digital course that teaches The Rewire Method, a process for changing the beliefs behind emotional eating, body-image struggles and old habits. The Rewire Method was created by Lina Viner, a Telezen MD co-founder. The course comes with lifetime access, and it is an educational practice, not medical treatment or psychotherapy.
