What to Eat on the Wegovy Pill: Diet and Nutrition
In one sentence
To get the best from the Wegovy pill, eat a balanced, reduced-calorie diet with plenty of protein, vegetables and fibre, drink enough water, and eat smaller, slower meals to help ease nausea.
At a glance
The Wegovy pill works alongside a reduced-calorie diet, not instead of one.
Prioritise protein, vegetables and higher-fibre foods to stay full and protect muscle.
Eat smaller, slower meals to work with your reduced appetite and ease nausea.
Limit greasy, fried and very sugary foods, which can make nausea worse.
Stay hydrated, aiming for 6 to 8 glasses of fluid a day.
Fibre and fluids help prevent constipation, a common side effect.
The Wegovy pill makes eating less feel easier by reducing your appetite, but what you eat still matters a great deal. Good food choices help you lose weight in a healthy way, protect your muscle, keep your energy up and reduce side effects. This guide covers what to eat, what to limit and how to handle nausea.
Key takeaways
Do you need to diet on the Wegovy pill? Yes. It is designed to be used with a reduced-calorie diet and more physical activity.
What should you eat more of? Protein, vegetables and higher-fibre foods, which keep you full and support healthy weight loss.
What should you limit? Greasy, fried and very sugary or fatty foods, which can worsen nausea.
How can food help with nausea? Smaller, plainer meals eaten slowly, and avoiding fatty foods, can make a real difference.
What should you eat on the Wegovy pill?
Aim for a balanced, reduced-calorie diet built around the NHS Eatwell Guide: base meals on higher-fibre starchy foods, fill at least a third of your plate with fruit and vegetables, choose protein such as beans, pulses, fish, eggs and lean meat, include some lower-fat dairy or alternatives, and keep foods high in fat, salt and sugar to small amounts.1 Because your appetite is smaller, making every meal count is more important than ever.
Why does diet matter when taking the Wegovy pill?
The Wegovy pill is licensed to be used alongside a reduced-calorie diet and increased physical activity, not on its own.2 The medicine helps control hunger, but the quality of your food is what drives healthy, lasting results and helps protect your muscle as you lose weight. Good habits are also what keep the weight off once you reach a stable dose.
Best foods to eat, and foods to limit
You do not need a special or restrictive diet. The simple table below shows the kinds of foods to lean towards and the ones to keep to smaller amounts.
Lean towards | Keep to small amounts |
Lean protein: chicken, fish, eggs, beans and pulses | Fried and greasy foods |
Plenty of vegetables and salad | Very sugary foods and drinks |
Wholegrain, higher-fibre carbohydrates | Large, heavy, fatty meals |
Fruit, within your 5 a day | Too much alcohol |
Water and low-sugar drinks | Fizzy and sugary drinks |
"I always tell people that the medicine and the plate work as a team. The Wegovy pill quietens your appetite, but protein, vegetables and fibre are what keep you full, protect your muscle and make the results last. Little changes you can keep up beat any crash diet."
How to eat to reduce nausea
Nausea is the most common side effect of the Wegovy pill, especially in the first few weeks and after a dose increase. Small changes to how you eat can help a lot:
Eat smaller meals more often rather than a few large ones.
Eat slowly and stop when you feel full, which happens sooner than before.
Choose plainer, blander foods such as toast, rice, crackers and lean protein when you feel queasy.
Avoid greasy, fried and very rich foods, which tend to make nausea worse.
Do not lie down straight after eating, and get some fresh air if you feel sick.
For more on managing this and other symptoms, see our guide to Wegovy pill side effects and how to manage them.
How much should you drink on the Wegovy pill?
Aim for 6 to 8 glasses or cups of fluid a day, mostly water.1 Staying hydrated helps prevent constipation, supports your kidneys and can ease that queasy feeling. Remember this is separate from the small sip of water you use to swallow the tablet, which should be no more than half a glass. See how to take the Wegovy pill correctly.
How to avoid constipation on the Wegovy pill
Constipation is a common side effect because the medicine slows digestion. To help prevent it, eat plenty of higher-fibre foods such as wholegrains, vegetables, fruit, beans and pulses, drink enough fluid, and stay physically active. If constipation becomes uncomfortable or does not settle, speak to your pharmacist or prescriber.
Do you need extra protein on the Wegovy pill?
Protein is especially important while you are losing weight, because it helps you feel full and helps protect your muscle. Include a source of protein at each meal, such as eggs, fish, chicken, dairy, beans, lentils or tofu. The Eatwell Guide also suggests at least two portions of fish a week, one of them oily.1
Can you drink alcohol on the Wegovy pill?
There is no absolute ban, but it is sensible to keep alcohol to a minimum. Alcohol adds empty calories, can make nausea worse and may affect your blood sugar. If you do drink, stay within the UK guideline of no more than 14 units a week, spread over several days. If you feel unwell when combining alcohol with the medicine, it is best to avoid it.
