Your first week on a GLP-1 is mainly a chance to notice what is different for you. You do not need a detailed diary or a dramatic change on the scale. A few steady notes can make it easier to describe your experience accurately at a review appointment, especially if your appetite, digestion, or daily routine feels different from usual.
Begin with the practical basics: the date you started, the medicine and strength written on your prescription, and the time you took or injected it. Keep the medicine box or patient leaflet nearby rather than relying on memory. These details are useful context if you later need to speak with your prescriber or pharmacist.
For the next seven days, make a short note about appetite at the times it normally matters to you. You might write whether you felt hungry before a meal, whether you became full sooner than expected, whether food seemed unappealing, or whether you still felt satisfied a few hours later. There is no ideal appetite score. The value is in seeing your own pattern, not comparing it with someone else’s.
It also helps to note the shape of your meals rather than trying to grade them. Record roughly when you ate, whether a meal was smaller or later than usual, and whether eating felt comfortable. Add a brief note on drinks if you have found it harder to drink as normal. If you have diabetes or another condition with a nutrition plan, continue to follow the plan agreed with your healthcare team.
Digestive notes can be particularly useful in the first week. A simple entry such as “mild nausea before breakfast,” “constipated for two days,” or “felt fine after dinner” is more helpful than trying to explain the cause. Include any vomiting, diarrhoea, abdominal discomfort, or injection-site change, along with when it happened and whether it affected food, fluids, work, sleep, or usual activities.
Weight is optional in week one. If weighing helps you, use the same scale and similar conditions each time, then keep the number in context. A single reading cannot show the whole story, and early changes can reflect normal day-to-day variation as well as changes in routine. Some people prefer to wait until the end of the week rather than step on the scale every day.
At the end of the week, read back through your notes and circle only the patterns that would matter in a conversation: a symptom that keeps returning, difficulty eating or drinking, a large change in appetite that is hard to manage, or anything that feels concerning. Contact your prescriber or another qualified healthcare professional for treatment questions, persistent side effects, or symptoms that worry you. Do not change your dose, schedule, or medication from a tracking note alone.
