Eating & nutrition
During a GLP-1 course you often eat less automatically due to a stronger feeling of satiety. It remains important to get enough protein, fluids and fibre, so that you lose weight in a healthy way and preserve muscle mass as much as possible. This is general information; a dietitian or your healthcare provider can give you personal guidance.
Less appetite, smaller portions
GLP-1 medicines slow down gastric emptying and influence your appetite, so you feel full sooner and for longer. Many people therefore eat smaller portions. Eat calmly and stop when you are full; eating too much can trigger nausea.
Enough protein for your muscles
With weight loss there is a risk that you lose muscle mass as well as fat. Enough protein can help to better preserve muscle mass. Spread protein throughout the day and choose, for example:
- dairy, eggs, legumes;
- fish, poultry or lean meat;
- plant-based protein sources such as tofu or tempeh.
Combine this with physical activity where possible to maintain muscles.
Fluids and fibre
Gastrointestinal complaints such as constipation occur during a course. Drinking enough and a fibre-rich diet can help keep digestion running smoothly.
| Fluids | Drink enough water spread throughout the day |
| Fibre | Vegetables, fruit, wholegrain products and legumes |
| Pace | Eat calmly and in small amounts |
The role of guidance and a dietitian
A dietitian or lifestyle coach can help draw up an eating pattern that suits your situation and goals. This prevents a one-sided diet and helps you build healthy habits that are also sustainable after the course. There is no strict standard diet that applies to everyone; personal advice works best.
