The best foods to eat on Wegovy — and a few to think twice about

Step 1, put protein at the centre of every meal

The single most important dietary shift on semaglutide is getting enough protein. Because your appetite falls and your portions shrink, the risk of consuming too little protein is real, and insufficient protein while in a calorie deficit speeds muscle loss, not just fat loss. That matters for long-term metabolic health and for keeping weight off once treatment ends.

Good sources to build meals around include eggs, chicken, turkey, white fish and oily fish such as salmon and mackerel, Greek yoghurt, cottage cheese, lentils, chickpeas and tofu. These are all nutrient-dense in a smaller volume, which suits the smaller appetite that Wegovy produces. Red meat is fine in moderation, but heavily marbled cuts or processed meats like sausages tend to be higher in saturated fat and can worsen nausea.

A practical check: before you eat, glance at the plate and ask whether protein takes up roughly a third of what is there. If it does, you are probably in the right territory. If the plate is mostly carbohydrate, add a portion of something from the list above. NHS guidance on healthy weight and nutrition supports protein adequacy as central to any weight-management dietary approach, and this applies especially when your overall intake is reduced by treatment.

Step 2 (fill the rest of the plate with vegetables and wholegrains

Non-starchy vegetables) broccoli, spinach, courgette, green beans, peppers, cucumber, tomatoes, are low in calories, high in fibre and vitamins, and filling relative to their volume. They are ideal when portions are smaller. Leafy salads, roasted vegetables and vegetable-based soups all work well and are generally well tolerated even in the early weeks of treatment.

Wholegrains such as oats, brown rice, quinoa and wholegrain bread provide sustained energy and support digestive function. They are a better choice than refined carbohydrates partly because they digest more slowly and cause less of a blood-sugar spike, and partly because on a reduced overall intake, every calorie needs to work harder nutritionally. That said, very large portions of dense wholegrains can contribute to bloating for some people, so portion sizes still matter.

For people exploring how to structure their eating more formally, the Wegovy meal planning guidance on this site goes into weekly structure and portion balancing in more detail. Keep refined grains, white bread and sugary cereals to a minimum, they tend to spike hunger again quickly, working against the appetite-modulation that semaglutide provides.

Step 3, manage the foods that make side effects worse

Nausea is the most commonly reported side effect of Wegovy, especially in the early months and after each dose increase. Certain foods reliably make it worse. Very fatty meals (fried food, heavy cream sauces, pastry) sit in the stomach for longer because fat slows gastric emptying further on top of what semaglutide already does. That combination often produces prolonged nausea or reflux.

High-sugar foods and drinks, including fruit juice, fizzy drinks and heavily sweetened snacks, can cause rapid blood-sugar swings that interact poorly with how semaglutide affects digestion. Alcohol is worth limiting too: it adds empty calories, lowers the threshold for nausea and can impair the dietary choices that support your progress.

Practical adjustments that many people find helpful: eat slowly, chew thoroughly, stop when comfortably full rather than when the plate is empty, and avoid lying down immediately after eating. Small, regular meals are usually more comfortable than larger ones. Dehydration can amplify nausea and constipation, both of which are listed side effects of semaglutide, keeping fluid intake up throughout the day is one of the easier habits to maintain. The NHS semaglutide medicines page covers the full side-effect profile and advises when to contact a prescriber.

Step 4, think about how treatment fits into your overall approach

Wegovy is a licensed weight-management medicine, not a dietary supplement, and it works best alongside consistent lifestyle changes rather than instead of them. The clinical trials that supported its approval combined the medicine with a reduced-calorie diet and increased physical activity. Both remain relevant throughout treatment.

Strength-based activity is worth mentioning here because it directly supports muscle preservation while in a calorie deficit. This does not need to be the gym; resistance bands, bodyweight exercises and carrying shopping all count. Pairing this with adequate protein gives the body what it needs to maintain lean mass.

If you are considering Wegovy and want to understand the clinical picture more fully, including how it compares with other licensed treatments, the Wegovy overview and a look at how semaglutide differs from Ozempic are worth reading. Ozempic is semaglutide too, but it is licensed for type 2 diabetes rather than weight management, a distinction that matters when choosing a treatment route. A prescriber who reviews your full health picture is always the right person to advise on which approach suits you. If you would like to explore your options with a clinical team, the treatment consultation page explains how the process works. Our clinical team reviews every consultation personally, there is no algorithm between you and a prescriber's decision. Check your eligibility and see whether treatment is suitable for you, and if you want further guidance on sourcing your prescription safely, our pages covering what makes a trustworthy website for Wegovy, how to identify the best site for Wegovy and what to look for in the best place to get Wegovy are a good starting point.
