Wegovy Diet: What to Eat for Best Weight Loss Results

Wegovy is a popular and effective once-weekly weight loss injection that contains the active ingredient semaglutide. It works by suppressing your appetite and reducing food cravings.

Wegovy can help you lose 21% of your initial weight on average, and combining it with a healthy and balanced diet is key to its effectiveness.

Here, we discuss how diet can boost Wegovy’s effectiveness and share tips on which foods to eat and avoid while on Wegovy to maximise weight loss.

Although there is no official Wegovy diet, eating a healthy, balanced diet that prioritises the macronutrients, healthy fats and proteins, alongside fibre and micronutrients to provide your body with the vitamins and minerals it needs to maximise weight loss and function efficiently, is key.

Wegovy contains semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist. It works by attaching to the GLP-1 receptors in the body to:

• keep you feeling fuller for longer after meals
• reduce cravings
• slow digestion
• regulate blood sugar levels

Wegovy makes you feel less hungry to stop you from overeating, but this alone won’t help you lose weight. You will need to combine your weekly injections with lifestyle changes, such as adopting healthier dietary habits and increasing your exercise.

Wegovy will suppress your appetite, making it easier to eat less, but it is important to choose nutritious foods and drinks that support your weight loss goals and provide the nutrition your body needs to stay healthy.

Here are some of the foods you should be eating and drinking with Wegovy:

Proteins

Prioritising lean proteins can aid weight loss in several ways, including increasing your sense of fullness, boosting metabolism, and preserving muscle mass while burning fat. One study found that, compared with a standard-protein low-fat diet, a high-protein low-fat diet leads to greater weight loss.

Some good examples of lean proteins to eat while on Wegovy are:

• lean, skinless chicken and turkey breast
• fish and seafood, such as cod, salmon, basa, mackerel, prawns, and crayfish
• eggs
• tofu and tempeh
• legumes, including lentils, chickpeas, edamame, black beans, and kidney beans

High fibre foods

Foods high in fibre can help regulate your appetite by making you feel fuller for longer, and they can also help manage potential side effects, such as constipation, by adding bulk to your stool and promoting regularity.

Choose foods that slowly release energy to curb overeating, such as:

• barley
• cruciferous vegetables (broccoli, cauliflower, cabbage)
• oats
• quinoa
• brown rice
• whole wheat pasta and bread
• non-starchy vegetables, like spinach, kale, courgettes, peppers, artichokes, aubergine, and celeriac
• fruits including berries, citrus fruits, apples, pears, and kiwis

Healthy fats

Not all fats are bad for you. Your body needs certain types of fats, particularly unsaturated fats, for better heart health, vitamin production, hormone synthesis, and appetite regulation. Studies have shown that increased intakes of polyunsaturated fat and plant-based monounsaturated fat are associated with less or no weight gain compared to saturated fat, trans fat, and animal monounsaturated fat intakes.

Healthy fat sources include:

• avocados
• oily fish such as salmon, mackerel, sardines, herring
• nuts (almonds, Brazil, pecans, and walnuts)
• seeds
• olive oil

Hydration

An often overlooked aspect of a healthy diet, especially during weight loss, is hydration. Because Wegovy slows digestion and reduces your appetite, it can lead to not drinking enough, dehydration, and can cause Wegovy side effects to get worse.

Some of the benefits of staying hydrated while taking Wegovy include:

• minimises and eases side effects, such as nausea, headaches, and constipation
• protects kidney function because dehydration puts your kidneys under extra pressure and can impact how well they work
• supports weight loss by aiding metabolism and helping to remove waste products from the body
• can stop you from overeating, as many people mistake thirst for hunger

As well as water, it can help to try sugar-free or low-sugar electrolyte drinks, especially if you are getting side effects like feeling or being sick, diarrhoea, or dizziness. Electrolytes are electrically charged minerals that are important for maintaining fluid balance, nerve and muscle function, and pH levels in the body. They include:

• calcium
• magnesium
• potassium
• sodium

As well as the foods you should prioritise on Wegovy, there are several that you should limit or avoid if you want to achieve the best results. Typically, this includes foods that are:

• high in unhealthy fat
• sugary
• rich in calories but with little nutritional content

Some of the foods you should limit on Wegovy include:

High-fat foods

High-fat and fried foods contain both saturated and trans fats. These are unhealthy fats, and eating them regularly is linked to higher rates of obesity, type 2 diabetes, high cholesterol, and heart disease.

These types of foods can also worsen Wegovy side effects. That's because Wegovy slows digestion, prolonging the time high-fat foods remain in the stomach and causing nausea, vomiting, indigestion, diarrhoea, and stomach discomfort.

Some examples of high-fat and fried foods you should limit or avoid while on Wegovy are:

• fast food, like pizzas, fried chicken, burgers, and kebabs
• chips and fries
• doughnuts, cakes, and pastries
• butter, lard, ghee
• full-fat dairy
• processed meat (ham, bacon, sausages, burgers)
• palm and coconut oil

Sugary foods and drinks

Foods and drinks high in sugar cause rapid spikes and crashes in blood sugar and contribute to weight gain. It’s important to limit or avoid:

• fizzy soft drinks
• energy drinks
• cakes and pastries
• sweets and chocolate
• desserts

Fizzy drinks

Fizzy drinks contain carbon dioxide. This is what makes them fizzy, but it’s also this that can make you feel bloated after drinking them. Drinking fizzy drinks on Wegovy can worsen side effects and make you feel uncomfortable, so where possible, swap them for water, herbal tea, or squash.

Processed foods

Ultra and high-processed foods are packed with added salt, fat, sugar, and preservatives to give them their flavour and prolong their shelf-life. This also means that they are calorie-rich but low in nutrients and include foods like:

• crisps, cakes, and biscuits
• ready meals
• takeaways
• processed meat
• sweets
• drinks that contain artificial sweeteners, like diet or “zero” options

For effective weight loss, you need to be in a calorie deficit, which means you are burning more calories than you consume. So, consuming these foods and drinks adds to your calorie intake, which can make it more difficult to lose weight.

Alcohol

Although there are no direct interactions between Wegovy and alcohol, it is best to avoid or limit your alcohol intake for several reasons, including:

1. Empty calories – Alcohol contains empty calories, which can stimulate your appetite, causing you to eat more and contribute to weight gain. The empty or hidden calories in alcohol can affect your calorie deficit, making it harder to lose weight.
2. Higher risk of dehydration – Alcohol is a diuretic, which means it promotes fluid loss from the body, leaving you at risk of dehydration if you do not replace it.
3. Worsens Wegovy side effects – Excess alcohol can cause adverse effects, like feeling or being sick, headaches, and diarrhoea. These are also side effects of Wegovy, so drinking alcohol can make these side effects worse.
4. Impaired blood sugar control – Alcohol and Wegovy cause your blood sugar to fall, which can be dangerous if not treated.

When taking Wegovy for weight loss, many people naturally eat less because of the medication's effects on their appetite, but it is important to eat a healthy, balanced diet not only to aid your progress but also to keep your body functioning properly. Focus on lean proteins, fibre-rich carbohydrates, healthy fats, and micronutrient-rich foods.

Here is a sample Wegovy meal plan designed for one person, using balanced portions to support sustainable weight loss while helping minimise side effects such as feeling sick.

Many Wegovy side effects are mild and go away on their own as your body gets used to semaglutide. In the meantime, many, including feeling or being sick, diarrhoea, constipation, and indigestion, can often be managed at home by making some small dietary changes.

Feeling or being sick

If you are feeling or being sick while taking Wegovy, it can help to:

• eat bland foods, like wholemeal toast and crackers
• eat smaller, more frequent meals rather than 3 large meals per day
• sip water throughout the day rather than gulping large amounts all at once
• avoid rich, greasy, and fatty foods
• incorporate ginger into your diet, which is known for its anti-nausea properties

Diarrhoea

Diarrhoea on Wegovy can be eased by:

• eating a BRAT diet (bananas, rice, applesauce, toast)
• avoiding alcohol, caffeine, fatty or fried foods
• sipping water throughout the day to avoid becoming dehydrated
• eating smaller, more frequent meals to avoid overloading your digestive system

Constipation

Constipation is a common Wegovy side effect that can cause discomfort. You can help to avoid or ease it by:

• drinking plenty of water and eating high-water-content foods, such as cucumbers to help soften stools
• eating foods that are high in fibre, such as lentils, beans, and wholegrains
• eating foods such as bananas, berries, and prunes

Indigestion

If you get indigestion or any other gastrointestinal side effects, you can:

• eat easy-to-digest foods, like porridge and bananas
• avoid lying down after eating or going for a gentle walk
• avoid acidic foods

Diet is just one aspect of your lifestyle that will need to be adjusted if you want to get the best results out of Wegovy. The medication will not work on its own and will require some effort and commitment to a healthier lifestyle. These habits will also be useful when you stop taking Wegovy to help you avoid regaining your lost weight.

Some of the other lifestyle changes you should consider are:

1. Tracking your food intake and hydration. Keep a food journal or use a food-tracking app to help you stick to your Wegovy diet plan and identify any “hidden” calories that may be affecting your progress.
2. Finding an exercise you enjoy. Choosing an exercise or physical activity you enjoy will help keep you motivated and make it more likely to become a habit. Daily activities, such as housework and gardening, also contribute to your activity level.
3. Managing stress. Stress can hinder your weight loss progress and influence your appetite, causing you to overeat. Activities like yoga, mindful eating, breathing, and meditation can help manage stress and can be helpful if you are a stress eater.
4. Managing portion sizes. If portion control is a problem for you, try using smaller plates to serve your food. For example, a side plate rather than a dinner plate can help restrict the amount of food you eat at mealtimes.
5. Timing your meals right. Eat regularly, we recommend three balanced meals a day. This can help minimise snacking in-between throughout the day and evening. It can also give your body time to digest, reducing side effects. Structured mealtimes can also help you avoid under-eating when experiencing pro-longed appetite suppression.

What is the “Wegovy diet”?

There is no specific Wegovy diet to follow when using the weight loss medication, but it is important to focus on high-protein, nutrient-dense, and high- fibre foods. These will help you manage your appetite, minimise side effects, and provide energy.

Can I drink coffee while on Wegovy?

Yes, you can drink coffee while taking Wegovy, but it is important to do so in moderation. That’s because caffeine can make Wegovy side effects worse. You may consider switching to decaffeinated coffee instead.

Can I drink alcohol while taking Wegovy?

Yes, you can drink alcohol while taking Wegovy, as there is no direct interaction between alcohol and semaglutide, but alcohol can make Wegovy side effects worse. So, it is recommended that you limit or avoid alcohol while taking Wegovy.

Can I use Wegovy if I’m vegan or vegetarian?

Yes, you can use Wegovy if you are vegan or vegetarian, but it requires careful diet planning to ensure you meet your protein and nutrient needs due to reduced appetite. Focus on nutrient-dense plant foods, such as tofu, tempeh, beans, lentils, nuts, seeds, and vegetables, to provide the macro and micronutrients your body needs to stay healthy.

How many calories a day should I eat on Wegovy?

It is recommended that you cut your calorie intake by around 600 calories from your recommended daily intake. This will help you move into a calorie deficit, where you burn more calories through exercise than you consume, promoting weight loss. Use our calorie deficit calculator to help you calculate how many calories you need to consume for effective weight loss.

What happens if I eat too little on Wegovy?

If you do not eat enough while on Wegovy, it can cause fatigue, nutrient deficiencies, hair loss, muscle loss, and fat loss. It can also make other common side effects worse, like feeling sick and dizziness. Not eating enough can also slow your metabolism, making it difficult to manage your weight in the long term.
