How to Overcome Weight Loss Plateaus on Weight Loss Injections

Feb 03, 2026 Weight Loss

Hitting a weight loss plateau can feel frustrating, especially when you have been doing everything right. If you have been using weight loss injections such as Mounjaro or Wegovy, it is completely normal to experience a stall around month two or three of treatment. The good news is that it is not a sign of failure and does not mean the medication has stopped working. Weight loss plateaus are a natural part of the journey. Annoying, sometimes disheartening, but normal.

This blog post is here to help you understand why plateaus happen, what you can change, and how to get your progress moving again with practical tips and reassurance.

Why Am I Not Losing Weight? Reasons for Stalling 

Understanding why weight loss slows down can help you feel more in control and far less discouraged. This knowledge also helps to plan for breaking a stall and getting yourself back on track.

Your Body is Adjusting

As you lose weight, your body needs fewer calories to function. This is known as metabolic adaptation, and it is a natural biological response. Your metabolism slows slightly as your weight drops, which can cause progress to slow temporarily.

The Initial Water Loss Has Passed

In the first few weeks of using weight loss injections, many people lose water weight quite quickly. After this early drop, weight loss tends to slow and become steadier. This can feel like a plateau, even though your body is continuing to burn fat at a healthier and more sustainable pace.

Lifestyle Habits May Have Shifted

As the excitement of starting treatment fades, it is easy to return to old habits without realising. You might be moving a little less, grazing on snacks more often, or being less mindful with meals. These small shifts can add up and affect your progress.

What to Change to Restart Weight Loss

If you feel like you are stuck, making a few targeted changes can help restart your progress without overhauling everything at once.

Track Your Food and Drink Honestly

Even with a reduced appetite, small extras such as nibbles or extra portions can slow your results. Try tracking your food and drink for a few days. This is not about restriction but awareness. You may spot patterns or habits that are holding you back. For example, if you find that 8 pm in front of the TV is a danger time for snacking, have water to hand and healthier (portion-controlled) snacks. You might choose this time to go and have a walk, fold some washing or take a bath, to try and break the habit of 8 pm unhealthy snack eating.

Increase Your Activity Level

If you are not moving much during the day, gentle activity like walking, swimming or yoga can give your progress a boost. If you are already active, try switching up your routine with strength training or different types of movement to challenge your body, breaking a stall and helping you get the weight loss moving again.

Focus on Protein and Fibre

Both protein and fibre are essential during weight loss. Protein helps preserve lean muscle and supports your metabolism. Fibre keeps you feeling fuller for longer and supports gut health. Try to include high-quality sources like eggs, fish, chicken, legumes, oats and vegetables in your meals.

Prioritise Sleep and Manage Stress

High stress and poor sleep can interfere with weight loss, often without us realising. Stress raises cortisol levels, which may slow fat loss, and a lack of sleep can increase hunger. Try to establish a calming evening routine, reduce screen time and aim for at least seven hours of rest per night.

Stick To Your Medication Schedule

Taking your injections on time and following your healthcare provider’s instructions is vital. Delayed or missed doses can affect how well the medication works, resulting in or contributing to a weight loss plateau.

How to Restart Progress

Once you have made a few changes, give your body time to respond. It might take a couple of weeks to see progress again, but that does not mean nothing is happening behind the scenes.

Celebrate non-scale victories

The number on the scales is just one part of your journey. Take note of changes in how your clothes fit, your energy levels, your mood and your confidence. These shifts are all meaningful signs of success.

Try Alternative Progress Measures

Scales can fluctuate for many reasons. Consider taking monthly photos, body measurements or tracking how far you can walk or how strong you feel. These alternative ways of measuring progress can be far more motivating and less stressful.

Speak To Your Healthcare Provider

If your progress has stalled for more than four to six weeks, it may be worth checking in with your provider. They can review your medication, offer support or help identify any medical factors that may be affecting your progress.

Keep Things in Perspective

Plateaus are a sign that your body is working hard to balance itself and protect you. They are not a setback, just a pause. Trust that progress will return and remind yourself how far you have already come.
