What to expect

A gentle week-by-week guide to the first month — adjusting, noticing the shifts, finding your rhythm, and settling in.

Starting GLP-1 medication can feel like a big shift, and it's completely normal to wonder what the first few weeks might look like. Everyone's experience is slightly different — this isn't a strict timeline, but a gentle guide to help you feel prepared.

Week 1: Adjusting

This is the phase where your body is starting to get used to the medication. Some people notice changes straight away, while for others it may take a few weeks. Both are completely normal.

  • A reduced appetite
  • Feeling full sooner than usual
  • Less interest in food

You may also experience some side effects, such as nausea, bloating or feeling overly full. What can help:

  • Keeping meals small and manageable
  • Eating regularly, even if hunger feels different
  • Staying hydrated

Week 2: Noticing the shifts

By this point, appetite often feels more noticeably reduced, although it can still vary for many. Starting on the lowest dose allows you to get used to the medication and minimise the likelihood of side effects, so it’s completely normal if you don’t notice any changes yet.

You might notice:

  • Eating smaller portions without trying
  • Feeling satisfied more quickly
  • Less 'food noise' or constant thinking about food

Side effects may still be there, but for many people, they begin to ease slightly.

What can help:

  • Maintaining some structure with meals
  • Avoiding long gaps without eating
  • Starting to notice what foods feel comfortable for you

Week 3: Finding your rhythm

Things often start to feel a little more predictable around this stage.

You may begin to feel:

  • Feeling more settled with your appetite
  • More confidence with portion sizes
  • Being a bit more in tune with what your body needs

Some people may notice weight changes, but not everyone will – and that’s completely okay.

What can help:

  • Building consistency with meals
  • Gently introducing supportive habits
  • Paying attention to energy levels

Week 4: Settling in

By this point, your body is usually becoming more familiar with the medication.

You might notice:

  • A more stable appetite
  • Fewer or more manageable side effects
  • A clearer sense of what works for you

Progress can still feel non-linear, and that’s expected.

What can help:

  • Keeping things steady rather than doing more
  • Continuing to prioritise nourishment
  • Building habits that feel realistic for you

What progress can look like

In these early weeks, you might notice:

  • Feeling more in control around food
  • Fewer cravings
  • Feeling satisfied with less
  • More consistency in your eating
  • Some weight loss

When to reach out

Most side effects are mild and temporary, but it's important to get support if something doesn't feel right or you just want to check in.

This includes:

  • Ongoing or severe nausea
  • Difficulty eating or drinking
  • Dizziness or very low energy
  • Anything else that feels important to you

You don't need to manage this alone. We've got you.
