How your body uses insulin
Insulin resistance is one likely reason some people lose weight more slowly. More on this below.
Free GLP-1 care guide
Losing slower than you hoped? You are not off track.
Everyone responds to a GLP-1 in their own way. This guide explains what it means to be a slow responder, why it happens, and what you can do to help your body along.

- There is no "normal" number. There is no standard amount you should be losing each week. Your pace is your own.
- Slow is not the same as stuck. A slower pace is common, and it is not a sign you did something wrong.
- Daily habits help. Water, protein, movement and strength training give your body more to work with.

Part 1 · Every body is different
No two journeys look alike. Neither do the numbers.
Someone else's fast start is their story, not a goal you missed. How fast you lose weight on a GLP-1 depends on many things, and most of them have nothing to do with willpower.
Where you are in your doses
GLP-1 doses start low so your body can adjust, then go up in steps over time. Where you are on that path shapes your pace.
Your hormones
Perimenopause, menopause, PCOS and thyroid problems can all change how your body stores and burns energy.
Sleep and stress
Short sleep and high stress raise hormones that make your body hold on to weight and want more food.
Other medicines
Some antidepressants, steroids, insulin and other medicines can slow weight loss. Never stop one on your own.
Your starting point
Your age, muscle mass, past dieting and how long you have carried extra weight all shape your pace.
Part 2 · What slow response means
Slow is not the same as stuck.
A slow responder is someone whose weight comes off more slowly than average on a GLP-1. It often means you will need more time. One likely reason is insulin resistance: the more insulin resistant you are, the more work your body has to do before the scale starts to move.
- 1
Insulin moves sugar into your cells
When you eat, your blood sugar goes up. Insulin is the hormone that moves that sugar out of your blood and into your cells for energy.
- 2
Your cells stop listening
With insulin resistance, your cells do not respond well to insulin, so your body makes more and more of it to get the job done.
- 3
High insulin holds on to fat
Insulin tells your body to store energy. When insulin stays high, your body has a harder time using stored fat.
- 4
It can take time to settle
GLP-1 medicines help your body manage blood sugar and insulin. If you start with more insulin resistance, that can take longer to settle.
Signs you may be insulin resistant
- Prediabetes or type 2 diabetes, or a high A1c on a lab test
- PCOS (polycystic ovary syndrome)
- Weight that collects around your belly
- Dark, velvety patches of skin on your neck or underarms
- Perimenopause or menopause, or a family history of diabetes
Your care team can check with a simple blood test, such as A1c or fasting insulin.
Part 3 · What helps
Four habits that help your medicine do its job.
You cannot change how your body responds overnight. These four habits matter most for slow responders, because each one helps your body use insulin better or protect the muscle you have.
Habit 1
Stay hydrated
64+ oz water a day
GLP-1 medicines can turn down your thirst along with your hunger. Low water can leave you tired, feel like hunger, and make nausea and constipation worse.
A 32-ounce bottle filled twice gets you to 64. Sip all day, since big gulps can feel uncomfortable.
Habit 2
Eat protein first
25–30 g protein each meal
When your appetite is small, every bite counts. Protein keeps you full, steadies your blood sugar and helps protect your muscle. Eat it first at every meal.
A common starting point is 0.7 grams of protein for each pound of your goal weight. Your care team can help you set your number.
Habit 3
Move every day
30 min movement most days
Working muscles can pull sugar out of your blood without needing as much insulin. You do not need hard workouts. A walk counts.
Walk for 10 minutes after meals. Three 10-minute walks count the same as one 30-minute walk.
Habit 4
Build strength
2–3 days strength each week
If you add only one new habit, make it this one. Some of the weight lost on a GLP-1 can come from muscle, and more muscle helps your body use insulin better.
Start with chair squats, wall push-ups and glute bridges. No gym needed.
Build a meal
Tap foods to reach 25 g
0 g
Many people aim for about 25 to 30 grams of protein at each meal. Pick what you might eat at your next one.
Amounts are approximate. Your care team can give you a daily protein target that fits your body.

Part 4 · Track your progress
The scale is one number. Look at the whole picture.
Slow responders often make real progress before the scale shows it. Watch your trend over weeks and months, not days.
Signs your medicine is working
- Your waist is smaller, or your clothes fit looser
- You feel full sooner and think about food less
- Cravings are quieter, especially for sweets
- You have more energy during the day
- Your lab numbers improve, like A1c or blood pressure
Weigh once a week
Same day, same time, before you eat. Weight goes up and down day to day with water, salt, hormones and your cycle.
Measure your waist monthly
Measure at the level of your belly button. When you build muscle and lose fat, your waist can tell a better story than the scale.
Write down how you feel
Note your hunger, energy and sleep. Compare month to month, not week to week.

Putting it together
Your week, at a glance
Small habits, done often, add up. Start with one or two and build from there.
Every day1 of 4
Water and protein
Drink 64 ounces of water or more. Eat 25 to 30 grams of protein at each meal, and eat it first.
Most days2 of 4
Move for 30 minutes
Walk, ideally after a meal. Short walks count.
2 to 3 days a week3 of 4
Strength training
Do the starter routine from the guide, with a rest day between strength days. When 12 reps feel easy, add weight or a few reps.
Once a week4 of 4
Check in
Weigh in the same way each week. Once a month, add your waist measurement and look at the trend.
The guide also has a protein food list, a sample day of meals and a five-move strength routine. Get the guide
Part 5 · Talk to your care team
You do not have to figure this out on your own.
If you feel stuck, tell us. Your Belle care team can look at your whole picture and help adjust your plan. Do not change your dose or stop your medicine on your own.
Message your care team if
- Your weight and waist have not changed after several months on your medicine.
- Side effects make it hard to eat enough protein or drink enough water.
- You take other medicines and are not sure if they affect your weight.
- You think you may have insulin resistance, PCOS or a thyroid problem, or are in perimenopause or menopause.
- You want to talk about your dose or your next step.
What we may look at together
- Your dose and how fast it goes up
- Lab tests like A1c, fasting insulin or thyroid
- Your other medicines and health conditions
- Your sleep, stress and daily routine
“There is no ‘normal’ number. Your pace is your own.”
