There is a different conversation to have when appetite falls. What if nothing sounds appealing? What if you can manage a little food, but a full meal feels like too much?
After years of weight advice centred on eating less, I think those questions deserve proper attention too.
Where does this advice come from?
The Obesity Medicine Association published an explainer on 1 August 2026 about staying nourished during GLP-1 treatment. It draws on a 2025 joint advisory from four professional societies. This is expert guidance, not a new August treatment trial. [1] [2]
This article has not had a separate dietitian review. It is a starting point for understanding the questions, rather than a personal nutrition plan.
When smaller amounts feel more manageable
The advisory discusses smaller, more frequent meals when appetite is low, with foods that provide protein and other nutrients. Examples include yoghurt, eggs, fish, legumes, nuts or nut spreads, alongside a varied range of foods. Soups or nourishing smoothies may suit some people. Fluids need attention too. [2]
Those are possibilities, not a compulsory menu. Allergies, health conditions, tolerances, preferences and cost can all change what works.
The question I would start with is: what feels tolerable, accessible and easy to prepare today? Then, if that pattern continues, what might be missing?
Strength needs more than a protein target
The advisory emphasises that protein alone is not enough to preserve muscle without appropriate strength training. Food and movement need to be considered together and adapted to the person. [2]
That does not mean everyone needs the same number, supplement or exercise plan. I would rather see a workable plan than another target that ignores someone’s circumstances.
Weight can be one part of follow-up. Nourishment, strength and how you feel belong there too.
What I would ask for help with
What should I prioritise if I can only eat small amounts? How can we check nourishment and fluids? Do my health conditions or medicines change what I need? How will we support strength and know when treatment needs reviewing?
If vomiting or other symptoms stop you keeping fluids down, seek prompt medical advice rather than trying to solve it with meal planning. Ongoing difficulty eating also deserves a treatment review. [2]
In Australia, the Dietitians Australia directory can help you find an Accredited Practising Dietitian. You do not have to work this out alone. [3]
