Evidence-Based Guidelines for Eating on Semaglutide
An excellent study was published in the Obesity journal last year outlining nutritional guidelines for people taking weight loss medications like semaglutide. It highlighted key strategies to optimise results, prevent muscle loss, and avoid common nutritional deficiencies.
In this post, I’ve summarised the most important takeaways from that study in a clear and practical way—no medical jargon, just helpful tips you can actually use.
As a registered dietitian working closely with clients on their weight management journeys, I’m also sharing insights from my real-life experience helping people make sustainable changes that stick.

I’ve shared several helpful videos on weight loss medications, weight loss and healthy habits over on my YouTube channel. Feel free to watch, comment, say hi, and ask any questions—I’d love to hear from you there.
What Is Semaglutide?
Semaglutide is the active ingredient in medications like Ozempic, Wegovy, and Rybelsus. It’s actually been around longer than many people realize. Originally developed to help manage blood sugar in people with type 2 diabetes, it’s now widely used as a weight loss medication because of how effectively it reduces appetite and supports fat loss.
How Does it Work For Weight Loss?
Semaglutide is a GLP-1 medication. This mimics a hormone in your body called GLP-1 (glucagon-like peptide-1). This hormone plays a few key roles:
- It slows down stomach emptying, helping you feel fuller for longer
- It reduces appetite by acting on areas of the brain that regulate hunger
- It helps regulate blood sugar levels by supporting insulin production and lowering glucose release from the liver
In short, it helps you feel less hungry, eat less without extreme effort, and makes it easier to lose weight—especially when combined with supportive nutrition.
That said, instead of thinking of it as a simple "weight loss injection," it’s more accurate to view semaglutide as a tool that helps some people make healthier choices more often.
Key Takeaway
For example, it can:
- Reduce “food noise” (that constant chatter about eating)
- Lower cravings for less nutritious foods (e.g., one biscuit might feel satisfying)
- Naturally reduce alcohol intake for some people
- Help adjust portion sizes in line with a smaller or leaner body
As a dietitian, I’m often asked for my opinion on weight loss medications like semaglutide—and while I’ve written a full post diving into the pros and cons, I’ll say this: I’ve seen semaglutide genuinely transform lives for the better.
You can read my full breakdown here: Ozempic Diet for Weight Loss | A Dietitian's Perspective.
But here’s the catch: semaglutide doesn’t work for everyone, and even when it does, it works best when paired with the right habits. That’s exactly where this guide comes in—to help you fuel your body in a way that supports the medication and your long-term success.
How Much Semaglutide Do You Need for Weight Loss?
The appropriate dose of semaglutide will be decided between you and your doctor. Most people start on a low dose to minimize side effects and gradually increase over time.
- Ozempic is typically used up to 2 mg once weekly (though it’s officially prescribed for type 2 diabetes).
- Wegovy, which is specifically approved for weight loss, can be titrated up to 2.4 mg once weekly.
It’s important to note that dosing should always be guided and monitored by your doctor—not self-adjusted. The goal is to find the lowest effective dose that helps you see progress without significant side effects.
How Can I Get Semaglutide for Weight Loss?
Access to semaglutide depends on where you live and local regulations. In most countries, it’s only available by prescription and should be prescribed by a licensed healthcare provider. Whether or not it is covered by insurance can varied but it tends to be quite expensive if you have to pay out of pocket.
A word of caution: steer clear of online sources offering semaglutide without a proper consultation.
- Many of these are unregulated, and some products marketed as “natural Ozempic” or “compounded semaglutide” may be ineffective and worse unsafe!
There are lots of horror stories out there from taking knock off versions of these drugs, please don't go there!
Always speak with a doctor or pharmacist to ensure you're getting the real, medically-approved version of this medication.
How Semaglutide Affects Appetite and Eating Habits
As mentioned earlier, semaglutide helps reduce appetite through its effect on the GLP-1 hormone. This makes it easier to eat less without feeling constantly hungry.
One analogy I like to use with clients is this: semaglutide is like using stabilisers (training wheels) when you’re learning to ride a bike. It can support you as you learn to balance healthy eating habits—especially if you’ve struggled with consistency in the past.
But here’s the key: when you eventually stop taking the medication, the stabilisers come off. That’s why it’s so important to build habits—like balanced meals, mindful eating, and regular movement—that will keep you steady on your own two wheels long term.
What Is the Best Semaglutide Diet Plan for Weight Loss?
While semaglutide helps reduce appetite, the foods you choose still matter—a lot. The right nutrition can maximise the medication’s benefits, help you maintain muscle, and reduce side effects. Here are the key areas to focus on:
1. Prioritise Protein to Preserve Muscle
When you're eating less—whether from intentional dieting or medications like semaglutide—there’s a real risk of losing muscle mass along with fat. In fact, up to 40% of weight lost can come from lean muscle, which is not ideal for long-term health or metabolism. That’s why Ozempic and muscle loss has become a growing concern, especially as more people use GLP-1 medications that suppress appetite. To prevent this
- Include lean proteins like chicken, turkey, fish, tofu, eggs, cottage cheese and Greek yogurt.
- Add plant-based proteins such as lentils, beans, quinoa, and edamame.
- Aim for a protein source at every meal and snack to support muscle repair and satiety.
- Read my full post on increasing protein intake for even more quick wins on how to boost your protein throughout the day.
How much protein do you need?
The general recommendation is 1.2–2.2 grams of protein per kilogram of body weight per day.
- For most people, that’s around 0.5–1 gram per pound of actual body weight.
- If you are in a larger body, speak with a dietitian about using your adjusted body weight for more accurate needs. You can book an online dietitian consultation here.
- If you have a medical condition (like kidney disease), please check with your doctor or dietitian before increasing protein.
2. Increase Fibre for Fullness and Digestion
Since semaglutide slows digestion, fibre becomes even more important for:
- Preventing constipation
- Supporting gut health
- Helping you feel full between meals
Focus on:
- Whole grains like oats, brown rice, and wholemeal bread
- Plenty of vegetables—at lunch, dinner, and even breakfast if you’re eating savoury meals
- Beans, lentils, and chickpeas (great sources of soluble fibre)
3. Stay Hydrated to Manage Side Effects
Hydration is key—especially when it comes to managing nausea and digestive discomfort. Semaglutide drugs like Ozempic can reduce your thirst as well as your appetite, so it’s important to be extra mindful about drinking enough water throughout the day.
- Aim for at least 2 litres (about 8 cups) of fluids per day—but the best way to know if you’re properly hydrated is to check your urine. It should be pale yellow, not dark or concentrated.
- If plain water isn’t appealing, don’t worry—herbal teas, sparkling water, or diluted no-added-sugar squash all count toward your fluid intake. Some people also find cold drinks more soothing than room temperature, especially if they’re experiencing nausea.
- I often suggest that my clients set mini alarms or reminders on their phone to prompt them to drink at regular intervals throughout the day—and they find this super helpful. It’s a simple way to stay consistent with hydration, especially when your natural thirst signals are dialed down by semaglutide.
4. Focus on Balanced, Smaller Meals
Large portions can cause discomfort when you’re on semaglutide—especially in the evening. Try:
- Spacing out meals and snacks across the day
- Eating slowly and chewing thoroughly
- Avoiding overly processed or greasy meals, which can trigger nausea or bloating
5. Make Sure You’re Still Eating Enough
With a reduced appetite, it can be tempting to eat as little as possible to lose weight faster. But:
- Too few calories = muscle loss and fatigue
- 1200–1500 kcal/day for women and 1500–1800 kcal/day for men are general minimums set in the nutritional recommendations
Eating less than that can compromise your metabolism, mood, and nutrient intake. The goal isn’t just to eat less—it’s to nourish your body well while your appetite is naturally smaller.
Semaglutide Diet Mistakes (and How to Avoid Them)
Even though semaglutide helps reduce appetite, it’s still very possible to undermine your progress with some common nutrition and lifestyle missteps. Here’s what I see most often—and how to fix them:
Mistake 1: Relying Too Much on Semaglutide Without Lifestyle Changes
Some people assume the medication will do all the work. Others drastically under-eat or rely on highly processed foods, which can lead to:
- Fatigue
- Muscle loss
- Nutrient deficiencies
The Fix:
Use semaglutide as a support tool, not a substitute for healthy habits. It’s usually better to aim for slow, steady weight loss than rapid drops that compromise your health.
Mistake 2: Ignoring Nausea and Digestive Issues
Nausea, bloating, and constipation are some of the most common side effects—often made worse by greasy food, eating too quickly, or not drinking enough water. If you don't proactively try to avoid these side effects it may impact your ability to stay on these medications long enough to achieve the results you are after.
The Fix:
- Start with smaller meals and eat slowly
- Avoid fried, spicy, or overly rich foods
- Stay hydrated and include fibre-rich foods
- If symptoms persist, speak with your doctor—your dose may need adjusting
Mistake 3: Skipping Behaviour Change
Some people get fixated on the number on the scale and forget that lasting weight loss requires habit change. If semaglutide is paused or stopped, old patterns can creep back in.
The Fix:
Use this time to build habits around:
- Planning balanced meals
- Understanding hunger/fullness cues
- Creating a realistic routine you can maintain long term
By avoiding these common mistakes, you’ll set yourself up for better results, fewer side effects, and a more sustainable, healthy relationship with food.
What Are the Best Foods to Eat When Prescribed Semaglutide
When you're on semaglutide, you are likely eating less. Therefore the quality of the food you eat becomes even more important. Here are the best types of foods to include:
High-Protein Foods
- Grilled chicken, turkey, eggs, Greek yogurt, cottage cheese
- Tofu, tempeh, beans, lentils, edamame
- Protein shakes (especially if appetite is low)
High-Fibre Carbohydrates
- Oats, brown rice, whole grain breads and wraps
- Quinoa, barley, bulgur wheat
- Vegetables (aim for 2+ servings per meal)
Healthy Fats (in small amounts)
- Avocado, olive oil, nuts, seeds
- Fatty fish like salmon or sardines
- Nut butters (spread thinly—high fat can sometimes worsen nausea)
Hydrating Foods
- Soups, smoothies, herbal teas
- Water-rich produce like cucumber, oranges, berries, and melon
Pro tip: Follow the balanced meals formula—where protein, fibre, and fat work together.
Foods to Avoid When Using Semaglutide
To reduce nausea and digestive discomfort, it’s best to limit greasy, fried, or highly processed foods. Also, avoid excessive alcohol, which can risk low blood sugars.
To reduce uncomfortable side effects, it’s best to avoid:
- Greasy or Fried Foods -These can be harder to digest and may worsen queasiness.
- Overly Sweet or Sugary Foods -Desserts, pastries, sugary drinks—these can cause blood sugar spikes followed by a crash, and may increase nausea in some people.
- Highly Processed Meals - Fast food and packaged snacks may be low in nutrition and high in fat or sodium—leading to bloating and sluggishness.
- Large, Heavy Meals - Overeating—especially at night—can be uncomfortable due to slower digestion on semaglutide.
Can I Drink Alcohol While on Semaglutide?
Moderate alcohol consumption is generally safe, but excessive drinking can increase the risk of low blood sugar (hypoglycaemia) and worsen nausea. It’s best to drink in moderation and with food. Alcohol can negatively impact sleep too, impacting cravings, energy and even muscle mass.
Interestingly though most people find their alcohol cravings decline when they start taking these medications!
In short: moderation is key.While alcohol isn’t strictly off-limits, it can increase certain risks when you’re on semaglutide:
If you choose to drink:
- Stick to 1–2 standard drinks
- Always consume with food
- Avoid sugary mixers and heavy cocktails
- Consider skipping alcohol entirely if it makes your side effects worse
What Vitamins Should I Take With Semaglutide?
Semaglutide itself doesn’t deplete any specific nutrients—but if you’re eating less overall, your intake of essential vitamins and minerals may naturally drop. Additionally individuals with obesity are at increased risk of micronutrient deficiencies.
Calcium and vitamin D are micronutrients of public health concern for adults in the US, but its always best to speak to your individual doctor or dietitian to find a supplement regimen and dose that is correct for you.
For example, if you are found to have certain vitamin deficiencies you may need to short term take a higher dose than usual until optimal baseline levels are restored.
Some supplements can also interact with drugs so personalisation is really key here.
Tips for Meal Prep and Planning
One of the biggest challenges while taking semaglutide is eating well when your appetite is low or your routine is off. That’s where a little planning goes a long way.
1. Prep Simple Proteins Ahead of Time
- Grill or bake chicken breasts, hard boil some eggs, or cook a pot of lentils or quinoa.
- Keep ready-to-eat protein options like Greek yogurt, protein shakes, or tofu on hand.
2. Wash and Chop Veggies in Advance
You’re far more likely to eat them if they’re easy to grab and cook. I recommend prepping mixed greens
3. Plan 2–3 Balanced Meals You Enjoy and Rotate Them
Don’t overcomplicate. Repetition is fine if the meals are satisfying and nutrient-rich.
4. Keep a Short Grocery List on Your Phone
Include your go-to protein, fibre, and hydration foods. You’ll save time and make healthier choices automatically.
💡 You don’t need to prep every single meal. Even 15 minutes once or twice a week can set you up for success.

FAQS
Weight regain is possible if healthy habits aren’t maintained. To prevent this, focus on sustainable dietary changes and regular physical activity. If semaglutidec is needed to help you maintain healthier habits, then you may need to accept that you may require a semaglutide medication in the long term.
No. It’s not suitable for individuals with a history of thyroid cancer, pancreatitis, or certain gastrointestinal disorders. Always consult a doctor before starting any medication for weight loss.
