A lower appetite can be part of the GLP-1 experience, but appetite that feels too low deserves attention. The important question for your notes is not whether you ate a "good" amount. It is whether food and fluids became hard to manage and how often that happened.
Once a day, record hunger, fullness, and intake in plain terms. You might write "not hungry until evening," "full after a few bites," "skipped lunch without meaning to," or "could drink normally but food felt difficult." If a full food diary feels burdensome, a brief summary is enough.
Add symptoms that affected eating or drinking. Nausea, vomiting, constipation, diarrhoea, heartburn, bloating, taste changes, abdominal pain, headache, dizziness, or fatigue can all change how intake feels. Record these separately from appetite so your prescriber can see the whole pattern.
Also note practical effects: missed medicines, difficulty working, trouble concentrating, disrupted sleep, avoiding social meals, or feeling anxious about eating. If you have diabetes or another condition where intake changes affect your treatment plan, include that context in your review notes.
Contact your prescriber, pharmacist, or another qualified healthcare professional if low appetite persists, worries you, or makes it hard to eat, drink, take medicines, or function normally. Seek urgent medical help if you cannot keep fluids down, feel severely unwell, or have severe or rapidly worsening symptoms.
