Your Wegovy shopping list: what to have ready before your first pen

Step 1, Stock protein first, everything else second

The single most common nutritional mistake people make on semaglutide is letting protein slip. When you're eating noticeably less overall, it's easy to meet a reduced calorie target with whatever's convenient, and convenient often means carbohydrate-heavy snacks rather than anything sustaining. The problem is that muscle tissue needs a steady protein supply, and weight loss without adequate protein tends to erode lean mass alongside fat.

For your weekly shop, the simplest rule is to start with protein and fill from there. Eggs are one of the most versatile options: quick, cheap, and digestible even on days when appetite is minimal. Plain Greek yoghurt (full-fat or low-fat, depending on your total intake) gives protein plus gut-friendly cultures. Tinned fish (sardines, mackerel, tuna) is worth keeping in the cupboard because it requires no preparation and stores well. Chicken breast and thigh both work; thigh is slightly easier on digestion for some people. Pulses such as lentils, chickpeas and butter beans add protein alongside fibre, which matters for the next step.

A quick habit worth building: before you close the fridge at night, check there's a ready protein source visible at eye level. It takes under a minute and means you're less likely to reach for crackers when hunger eventually returns.

The semaglutide overview on our site covers how the medicine works on appetite, which puts the protein priority in context.

Step 2 (Build your fibre and hydration aisle

Semaglutide slows the movement of food through the digestive tract) that's part of why it reduces appetite so effectively. The trade-off is that constipation is a genuine and common side effect for a proportion of people, particularly in the early weeks. Fibre and fluid are the two most reliable countermeasures, and both are cheap to stock up on.

For fibre, the practical choices are foods most people already recognise: oats, wholegrains, vegetables (courgette, broccoli, leafy greens), fruit with skin on (apples, pears), and the pulses already mentioned. The NHS recommends 30g of dietary fibre per day for adults, a target that gets harder to hit when you're eating smaller volumes, so choosing fibre-dense options rather than refined versions pays dividends. A slice of seeded wholegrain bread has roughly four times the fibre of standard white, for roughly the same space in your stomach.

Hydration is equally important. Nausea and reduced appetite can make it easy to go long stretches without drinking enough, and dehydration compounds GI side effects. Plain water is the baseline; plain herbal teas count. Coconut water and diluted fruit juice can help if electrolytes feel low. Soups (particularly clear broths with vegetables) are a practical way to get both fluid and nutrients when solid food is unappealing. Avoid carbonated drinks if you find burping or bloating troublesome in the early weeks.

For a broader picture of how nutrition interacts with weight-loss treatment, the treatment overview page is a good starting point.

Step 3, Decide what to leave off the list

This isn't about banning foods. It's about recognising that some foods are harder to manage on semaglutide, particularly during dose escalation, and planning accordingly.

Very greasy or heavily fried foods are the most commonly reported trigger for nausea during the first month. That doesn't mean they're permanently off the table, but having a freezer full of battered items in week one is asking for trouble. Similarly, large quantities of refined sugar (fizzy drinks, sweets, pastries) tend to give a brief energy spike followed by a sharp drop, which can amplify fatigue that some people already feel on a new dose.

Alcohol deserves a note of its own. It is not contraindicated by the medicine, but semaglutide can increase sensitivity to alcohol's effects in some people, and drinking on a reduced food intake amplifies this further. If you normally keep wine or beer at home as a default, simply restocking a smaller amount in the first few weeks is sensible. NHS guidance on semaglutide's side effects and interactions is worth reading before you start treatment.

On the practical side: smaller plates and smaller storage containers are a minor but real help. Batch-cooking and freezing individual portions means you always have a sensible-sized meal ready when appetite is low and cooking feels like a chore.

Step 4, Know what to monitor as you settle in

The shopping list evolves. Week one on 0.25mg may feel very different from week six on 0.5mg. Some people find they can manage a wider range of foods earlier than they expected; others find that a dose increase temporarily narrows what sits comfortably.

Keep a brief note (even a note in your phone) of any foods that consistently trigger nausea or discomfort. It's not scientific, but it makes adjusting your Wegovy shopping much faster the following week. The gut effects of semaglutide are generally temporary and most noticeable when doses change. If they persist or worsen, that's a conversation for your prescriber, not something to manage by diet alone.

It is also worth understanding what happens if you decide to stop treatment, because the dietary habits you build on Wegovy matter for what comes after too. The page on stopping Wegovy covers what the clinical picture looks like, and the what happens after you stop page addresses long-term weight management. Both are worth reading before you start, not just at the end.

If you have questions about cost alongside planning your treatment, the Wegovy cost in the UK page sets out an honest view of what private treatment involves and what a legitimate price actually covers.
