Why am I not losing weight on Mounjaro?

There can be many reasons you are not losing weight on Mounjaro, ranging from health and lifestyle to the dosage you are currently taking. In this blog, we will go over all the possible reasons you may be having trouble with the weight loss drug and how to overcome them to meet your goals.

Firstly, Mounjaro is not a magic pill that you take, and overnight, you drop 20kg. It does take time to work; your body needs to adjust, and then you need to increase to the right maintenance dose gradually.

A study has shown that you can lose approximately 20% of your body weight [1] while taking the medication at a dose of 15mg over 72 weeks, which is incredible. However, if you are not getting these results and have stopped losing weight or never lost weight at all, this blog is designed to help you determine why.

5 Key Takeaways: Why am I not losing weight on Mounjaro?

• Mounjaro isn’t a quick fix—be patient.
  Weight loss with Mounjaro takes time. Your body needs to adjust, and you may need to slowly increase your dose before seeing significant results.
• Your diet and activity matter a lot.
  Even on Mounjaro, you need to eat fewer calories than you burn and stay active. If you overeat or don’t move enough, weight loss will be slow or may not happen.
• You might not be on the correct dose yet.
  Many people need to work up to a higher dose of Mounjaro to see the best results. Talk to your doctor if you think your dose is too low.
• Plateaus and slowdowns are normal.
  It’s common to stop losing weight for a while, even if you’re doing everything right. Don’t get discouraged—stay consistent and adjust your habits if needed.
• Other factors can affect your progress.
  Stress, certain health conditions (like thyroid problems), or some medicines can make weight loss harder. If you’re stuck, check in with your doctor for support.

What is Mounjaro?

Before we delve into why you are not losing weight whilst on Mounjaro, let’s have a quick refresher on what Mounjaro is and how it works.

Mounjaro is a weight-loss injection made by Eli Lilly. The main ingredient is tirzepatide.

What makes Mounjaro different is that it mimics two natural hormones from your body:

• GLP-1 (Glucagon-Like Peptide-1) and
• GIP (Glucose-Dependent Insulinotropic Polypeptide).

These are called incretins. Incretins help control your blood sugar and your weight.

1. They make you feel less hungry, so you eat less.
2. They help you feel full for longer after eating.
3. They slow down how fast your stomach empties food.

Scientists first saw that using both GLP-1 and GIP together helped mice with diet-related obesity lose more weight than using just one hormone [2]. Because of these strong results, Eli Lilly patented tirzepatide in 2016 [2]. Later, they proved in large studies (called the SURMOUNT trials) that it works for people, too.

The table below shows how GLP-1 and GIP help with weight loss.

Because Mounjaro uses both GLP-1 and GIP, it’s sometimes called a “twincretin.” These two hormones help you lose weight in three main ways [2]:

How much weight will I lose with Mounjaro?

Big studies called the SURMOUNT trials have shown that Mounjaro helps people lose weight.

The SURMOUNT-1 Trial:

This study looked at people who did not have diabetes but were overweight or obese. To join, people needed a body mass index (BMI) of 30 or more, or a BMI of 27 or more, plus a health problem like high blood pressure. The study lasted for 72 weeks (about a year and a half).

People who took the highest dose of Mounjaro 15mg lost up to 22.5% of their body weight on average. Nearly 90% of people lost at least 5% of their weight [3].

These results are impressive! For comparison, older weight loss medications, such as orlistat, typically help people lose only 3% to 8.6% of their weight [4]. In contrast, the newer medication, semaglutide, leads to an average weight loss of 12.4% [5].

So, Mounjaro is very effective for weight loss. But how much can you expect to lose each week? The table below provides details of the four weekly weight loss results from the SURMOUNT 1 trial.

Mounjaro weekly weight loss table

• Mounjaro 10mg: 22.4 kg lost (49.4 lbs)
• Mounjaro 15mg: 23.8 kg lost (52.5 lbs)
• Placebo: 2.6 kg lost (5.7 lbs)

You need to make changes to your diet

Your diet plays a crucial role in how you lose weight in general, not just when you are on Mounjaro. If you are not in a calorie deficit, it does not matter what you do. You will not lose weight. You need to consume fewer calories than you’re burning; otherwise, your weight will stay the same, or even worse, it may increase.

Mounjaro reduces appetite

Mounjaro aids the process by reducing your appetite, meaning you will consume fewer calories.

But what happens if you’re taking Mounjaro and still overeating?  This might be caused by being at the wrong dose, and you may need to work your way up to a higher maintenance dose.

The 500 kcal deficit

You want to be in a 500 kcal deficit; anything too little won’t result in significant weight loss, and anything too much will not be healthy.

As a general rule of thumb, the average man should consume 2500 calories[6] and will need to eat 2000 calories or less [7], and the average woman needs about 2000 calories and will need to eat 1500 calories to be in a deficit.

Please note that this is a rough estimate, and other factors, such as age, weight, and activity level, must be taken into consideration when calculating your calorific needs.

How to calculate your daily caloric intake

To calculate your daily caloric intake (also known as Total Daily Energy Expenditure, or TDEE), you need to follow these steps:

1. Calculate your Basal Metabolic Rate (BMR)

This is the number of calories your body needs at rest to maintain basic functions like breathing and digestion.

Mifflin-St. Jeor Equation (most commonly used) [8]:

• Men:
  BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) + 5
• Women:
  BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) – 161

2. Multiply BMR by an Activity Factor

This gives your TDEE – your actual daily caloric needs based on your lifestyle.

Activity Level	Description	Multiplier
Sedentary	Little or no exercise	1.2
Lightly active	Light exercise/sports 1–3 days/week	1.375
Moderately active	Moderate exercise 3–5 days/week	1.55
Very active	Hard exercise 6–7 days/week	1.725
Super active	Very intense training/physical job	1.9

Example (Female, age 30, 65 kg, 165 cm, moderately active):

Step 1 – BMR:
10 × 65 + 6.25 × 165 – 5 × 30 – 161 = 1,383 kcal

Step 2 – TDEE:
1,383 × 1.55 = ~2,144 kcal/day

This woman needs about 2,144 calories per day to maintain her current weight.

Adjusting for your goal:

• To lose weight: subtract 250–500 kcal/day
• To gain weight: add 250–500 kcal/day
• To maintain: stick to your TDEE

What is a calorie, and how will being in a calorie deficit help me lose weight?

The scientific definition of a calorie is a unit of energy equivalent to the heat needed to raise the temperature of water by 1 degree Celsius.[9]

In layman’s terms, calories are the energy your body gets when you eat or drink. Your body burns calories throughout the day and even when you sleep, and the more active you are, the more you burn.

If you eat more calories than you burn, you are in a surplus, and you will gain weight; if you eat exactly as much as you burn, you will be at maintenance, and your weight will be unchanged. And finally, if you are in a calorie deficit, you burn more calories than you are consuming.

What happens when you are in a calorie deficit?

When you eat fewer calories than you burn, you are in a calorie deficit. Your body uses its fat reserves to make up for the calories it is not taking in.

Your body burns the fat for fuel, and this process makes you lose weight[10].

By eating in a calorie deficit and exercising regularly, you will lose weight, and taking Mounjaro will make the process much easier.

What happens if your calorie deficit is too large?

Although a calorie deficit will help your body lose weight, eating too little and being in too much of a deficit will do more damage than good.

Not fueling your body adequately will slow down your metabolism[11], make your weight loss plateau, and even make possible side effects more severe.

Make sure that while you are losing weight, you are getting enough calories and nutrients (especially protein- read our blog Mounjaro and Protein) so you can lose weight safely and healthily.

Making healthier food choices

Although you don’t need to count every single calorie you eat when you are losing weight with Mounjaro, it is encouraged to keep a food diary and stay on track of your calories.

If you need help to do this, there are many apps available to track your calories and nutrients. This can help you ensure you are getting the proper nutrients your body needs, and you know exactly how much you are consuming.

The best way to get started is by making small changes over time. Start by drinking more water to keep yourself hydrated. You would want to swap calorie-dense foods for foods that are lower in calories, which will fill you up the same way and taste just as good.

Here are a few tips to get you started. For a more in-depth review, please read our blog, ‘The ultimate Mounjaro diet guide.’

Should you avoid saturated fats and opt for a low-fat diet?

It’s still smart to eat saturated fat in moderation and aim for a balanced diet, but the idea that saturated fat is very dangerous is now seen as old-fashioned.

Recent research shows that saturated fats may not be as bad for you as people once believed, and most people don’t need to limit them strictly [12].

The best way to stay healthy is to eat primarily whole, unprocessed foods and include different kinds of healthy fats in your meals.

• Not all saturated fats affect your body in the same way.
• What matters most is your overall diet, not just one nutrient.
• Some new studies say that eating a moderate amount of saturated fat—as part of a diet with lots of fruits, vegetables, whole grains, and healthy fats like olive oil, nuts, and fish—may not be as harmful as we used to think [12].
• The biggest health problems usually come from eating lots of processed foods, trans fats, and added sugars, not just from saturated fat alone.

Drink water, not fizzy drinks!

You can never drink enough water unless you’re drinking 8 litres a day; then maybe tone it down. Although fizzy drinks taste nice, they can be high in sugar and full of unnecessary calories.

It is best practice to avoid drinking your calories. Be mindful of what you are drinking, and if you must drink fizzy drinks, opt for the diet no-calorie alternative.

Also, if you ever get bored with water, try drinking squash; it’s low in calories and can be a nice change.

Exercise portion control

They say you can’t have too much of a good thing. Well, whoever said that was lying to you. You can still enjoy the foods you like; no one told you to be boring, but be mindful of the servings you have.

Take the takeaway out of your diet.

No one says you can’t have takeaways, but save them for a treat. Not only will you save money, but you will also be able to track your food better, as you don’t know how many calories there are in your favourite takeaway.

Change your cooking oil.

Certain oils are quite calorie-dense. By opting for a lower-calorie option or even a cooking spray, you can reduce a lot of calories from your diet, leaving room for foods you want and making losing weight easier.

More importantly, many vegetable oils are high in omega-6s and are pro-inflammatory, increasing the risk of heart disease [13].

Also, invest in an air fryer. You can be surprised at what you can make in it. It requires no oil, so it is healthier. It’s super easy to use, making cooking less of an inconvenience, and the food tastes just as good.

Small changes to your diet are the key

If you make small changes to your diet, these add up and will make losing weight much easier. This is, of course, assuming that you are not eating fried chicken every day; if that is the case, then a small change will not cut it!

If you opt for healthier options, you will not need to calorie count as much, and you will be able to lose weight comfortably at a healthy pace. If you are counting your calories and taking Mounjaro, weight loss is almost guaranteed; however, remember that these results take time.

Two days of tracking your calories will not yield the desired results overnight. Weight loss is often about making gradual changes over time and adopting healthier habits.

What should I eat?

It is important that you are fueling your body correctly when you are in a calorie deficit. You want to make sure your body is getting the right amount of nutrients so you feel good and have energy.

Even if you are counting your calories, it is important to make good choices of where your calories are coming from. If all your calories are from saturated fats, sugar and processed foods, not only will you have to eat less, but you also put yourself at risk of health complications like high cholesterol or diabetes.

Also, although fats have a bad reputation, new evidence is emerging that demonstrates that they can be beneficial to our health [12].

It is essential, therefore, to include them in your diet, as they are a nutrient that your body requires. Fat is a good energy source, and on top of that, it keeps you satiated between meals. It makes food taste nice, but beware of low-fat options, as they often use lots of sugar to mask the bland taste.

Always ensure that your diet is balanced and you are consuming the proper nutrients to stay healthy on your weight loss journey.

Recommended foods

Lean protein: chicken, eggs, fish, beef, Greek yoghurt, turkey and low-fat cheese

Fruits and vegetables: All of them, but be wary of juices and smoothies as some can contain a lot of sugar.

Carbohydrates: brown rice, potatoes, sweet potatoes, beans, lentils and quinoa

Fats: avocados, nuts, seeds and dark chocolate

Foods to avoid

• Refined carbohydrates: white rice, pasta and bread
• Processed foods: fast food, crisps, biscuits, chocolates, ice cream, pizza, fizzy drinks and cereal
• Alcohol
• SUGAR!

You need to be more physically active

It is essential to have an active lifestyle if your goal is to lose weight. The more active you are, the more calories you burn, making it easier to lose fat.

If you are not living an active lifestyle, then this might be why you are not losing weight.

Now you don’t have to train like a professional athlete; go at a pace you’re comfortable with and set achievable goals. It is possible to lose weight without exercise; however, exercising is very important to live a healthy lifestyle and would make it easier to lose weight.

Beginners- start with slowly increasing your activity levels

If you have never worked out before, the idea of exercising can be daunting, but it’s always important to remember that everyone started somewhere.

Begin with small steps, go for a walk once a week, then increase the distance and frequency each week.

Start small and gradually increase your activity levels; this approach will be more straightforward on your body and will help you feel healthier and more energetic.

Try to avoid pushing yourself too hard to begin with, as this can lead to burnout and leave you right where you started.

Additionally, being more active doesn’t mean just going to the gym every day; it can involve small changes, such as taking the stairs instead of the elevator, cycling instead of driving, or working at a standing desk. Just remember that every little helps.

Physically active- increase the intensity.

If you’re already physically active and not losing weight, it may be time to increase the intensity or frequency.

It is recommended to do around 30 minutes of cardiovascular activity three times a week. This can be jogging, swimming or cycling, etc.[14]

On top of that, it would be good to add some form of resistance training to your program at least twice a week, which helps with body composition and prevents you from losing muscle as you lose weight.[15]

Resistance training is essential because if you lose muscle as you lose fat, you will end up looking the same but weighing less, which isn’t the goal of your weight loss journey.

Mounjaro may need more time to work

Losing weight does not happen overnight. It happens by making small changes over time. Even with the help of Mounjaro, you still need to give your body time.

A study has shown that you can lose around 22.5% of your body weight[16] while taking it, but you have to remember this study was done over 72 weeks.

Just remember to build healthy habits and trust the process, and then success will be inevitable.

Everyone is different

Remember, no two people are the same; therefore, not everyone is going to react to the drug the same. It may work faster for some, and for others it may take longer to work. These differences are due to many factors such as:

Age

Your age can be a significant factor in your weight loss journey. As we age, it becomes increasingly difficult to lose weight due to a significant slowdown in our metabolism over time[17].

On top of this, your body may not be as robust, so you would take longer to recover from physical activity, making it harder to stay as active.

Starting weight

The heavier you are at the start, the faster the weight will come off. Also, if you started quite heavy, you might notice the weight loss tends to taper off at a certain point. This is expected. Just stay consistent with everything you are doing, and you will get your expected results.

Metabolism

Just like how everyone’s body is different, everyone’s metabolism is also different. If your metabolism is faster, you will burn more calories, and if it is slower, you will burn fewer. Please note that this comes down to factors such as age and genetics.

One thing to bear in mind when it comes to your metabolism is that if you starve yourself, you will end up slowing it down, so you may be tempted to skip meals, but that will be more harm than good.

Lifestyle

As expected, the lifestyle you lead will significantly impact your weight loss journey. The more active you are, the faster you are expected to lose weight, and if you aren’t very active, then it may take you longer.

Medications

Certain medications may hinder the weight loss progress or even make you gain weight. We would not advise you to stop taking these medications. Speak to a medical professional if you have further questions.

Heath complications

There are some health conditions which can hinder weight loss progress, such as PCOS and hypothyroidism. If you have these conditions or any questions, please speak to a medical professional for any guidance you might need.

How long will it take to lose weight?

Although everyone loses weight at different rates, studies have shown that:

• During the first month, you can expect to lose 1-3% of your body weight
• During the second month, you can expect to lose 6% of your body weight
• During the third month, you can expect to lose 8-9% of your body weight
• During your fourth month, you can expect to lose 11% of your body weight
• During your fifth month, you can expect to lose 12% of your body weight

(Average weight loss after 17 months is between 16-22.5% of your bodyweight[18])

You haven’t reached the right maintenance dose

The right maintenance dose is the dose at which you lose weight the most effectively. This is not the dose you start with; you need to work your way up. You always start from the lowest dosage, which is Mounjaro 2.5mg, and you slowly build up until you reach the desired maintenance dosage of either

• Mounjaro 5mg,
• Mounjaro 10mg or
• Mounjaro 15mg.

The dosages are increased this way so your body can get accustomed to the drug and reduce the risk of any possible side effects. To learn more about the side effects associated with Mounjaro, read our blog, ‘Mounjaro side effects’.

Can I stay on a lower Mounjaro dose?

You can lose weight on a lower dosage, and it’s perfectly fine to stay at the lowest possible maintenance dose, but weight loss will progress faster as you increase the dosage.

On average, after 72 weeks, participants taking Mounjaro 5mg lost 16% of their body weight, participants taking Mounjaro 10mg lost 21.4% of their body weight, and lastly, those taking Mounjaro 15mg lost 22.5% of their body weight [19]

You’re stuck in a plateau

Plateaus occur when you’ve been losing weight steadily, only to stop suddenly without adjusting your diet, exercise, or medication. This is perfectly normal, and it happens to many people when they are trying to lose weight.

This can happen for many reasons. If you were losing a significant amount of weight when you began your diet and lose weight too quickly, your body notices this and can go into ‘survival mode’.

Your body thinks there is a food shortage and will begin to store calories as fat to make sure it has energy reserves to survive. If this happens, your progress will slow down, but don’t worry, this won’t last forever.

Water weight

Another reason for your plateau could be due to water weight.

The human body is 60% water, and when we make lifestyle changes, we suddenly shed ‘water weight’[20].

Bear in mind that this is not fat loss. This weight is quickly replenished so that you may see a dramatic shift in the scale, but this may not last. Don’t let this discourage you; it’s a common experience that many people face. The water you lose is temporary, but the fat you lose will hopefully stay off long term if you are consistent.

Weight loss plateaus are part of the journey. Try not to panic and stay consistent, and you will get the results you’re after.

What to do in a plateau?

Firstly, do not get discouraged, carry on as usual and stay consistent, and you will work through the plateau.

Do not stop taking your medication or prematurely increase the dosage; this will cause more harm than good.

Stick to the schedule. If you are stuck in a plateau, maybe it’s time to make adjustments to your diet. Perhaps you need to adjust your calorie intake or look at your salt intake.

You may find that the reason for your plateau is related to your food intake; you could be eating either too little or too much.

Finally, a good way to break plateaus is to be more active, maybe increase the duration, intensity or frequency of your workouts.

You are too stressed

Having a stressful life can not only impact your mental health but also your physical health more than you think.

When you are under stress, your body releases a hormone known as cortisol. This hormone, when present in high levels, can lead to behaviours like binge eating, and your body will store everything as fat. This can be known as emotional eating, where you feel stressed or any other negative emotion and resort to food for comfort.

Cortisol and belly fat

It has been shown that there is a link between cortisol and food being stored as belly fat[21].

As your cortisol levels rise, so do your blood sugar levels. This increase prompts your body to produce more insulin, leading to weight gain.

Cortisol is also linked to muscle breakdown, which is counterproductive to your body composition goals.

You may have a health condition

There are certain health conditions which can hinder your weight loss goals, but it is always good to consult a professional before you jump to conclusions.

Health conditions that can hinder weight loss include:

• Thyroid disorders
• Diabetes
• Depression
• Hormone imbalances
• Vitamin deficiencies

These conditions all impact fat loss differently, and you may need some support to lose weight. If while you’re taking Mounjaro and you develop symptoms and stop losing weight, you should consult a health specialist.
