    Diet During GLP-1 Treatment: Dietitian's Advice

    Practical dietary advice for those being treated with GLP-1 – from protein needs to managing reduced appetite.

    Diet during GLP-1 treatment

    Quick answer

    With reduced appetite, every meal matters. Prioritize protein (1.2-1.6 g/kg), eat nutrient-dense foods, and avoid empty calories. Smaller portions more often can reduce gastrointestinal issues.

    When appetite decreases, it's extra important that every meal counts. Here we share the dietitian's best advice.

    Prioritize Protein

    Aim for 1.2-1.6 grams of protein per kg body weight daily. Protein preserves muscle mass and provides longer satiety. Good sources: chicken, fish, eggs, legumes, quark.

    Nutrient-Dense Choices

    With less appetite, empty calories (sugar, white bread, chips) are extra problematic. Choose foods with high nutrient density: vegetables, whole grains, nuts.

    Managing Side Effects

    Nausea is often relieved by smaller portions, eating slowly, and avoiding fatty food. Constipation is counteracted with fiber and fluids.

    Daily Goals

    • Protein at every meal
    • At least 25-30 g fiber
    • 1.5-2 liters of fluids
    • Vegetables at lunch and dinner
    • Limit sugar and alcohol

    Frequently asked questions

    Do I have to count calories?
    Not necessarily. Focus on quality rather than quantity. GLP-1 helps you eat less naturally.
    What if I'm not hungry at all?
    Try to eat regularly anyway, even if smaller portions. Don't skip meals entirely.
