You’ve set a weight loss goal and you’ve been making steady, sustainable progress toward it. Until you reach the point where you aren’t. The scale stops moving, even though you’re doing your best. This pause in your progress is called a weight loss plateau and it’s something that happens at some point to most people who are trying to lose weight.
It’s frustrating when the scale stops moving in spite of all the effort you’re putting in.
“People often do well with weight loss at first and stall out after several weeks even though they haven’t changed their diet or lifestyle,” said Karissa Valles, RD, a registered dietitian with Banner Health.
A plateau doesn’t mean you’ve failed. It means your body is adjusting. Here’s why plateaus happen and how a balance of what you eat and how active you are can help overcome them.
Why weight loss plateaus happen
“Weight loss plateaus can result from a variety of reasons,” Valles said.
How much you eat
As you lose weight, your body adapts and burns calories more efficiently. You don’t need as many calories to fuel your new body size. When you don’t need as many calories, if you don’t adjust your portion sizes or how often you snack, you may reach a plateau.
Changes in your appetite hormones
Weight loss can trigger increases in your hunger hormones and decreases in the hormones that make you feel full, which can make it harder to lose weight and keep weight off.
Exercise habits
Daily habits and movement matter. “The amount of energy you expend walking up the stairs, tapping your foot, cleaning, standing at your workstation, etc., are all activities that add up,” Valles said. You might unconsciously increase or reduce these activities over time. If you reduce them, that could play a role in a weight-loss plateau.
You may also be stuck on the same exercise routine without increasing your intensity or duration, instead of challenging yourself with more resistance or longer workouts over time. As your fitness improves, you may need to build intensity or duration to get over a plateau.
If you use exercise machines, you may rely on them to track the calories you burn. “These machines often overestimate those calories,” Valles said. If you typically exercise with a treadmill, elliptical, stationary bike or other machine and you’re in a plateau, you may need longer or more intense workouts to overcome it.
Other potential causes
You may hit a plateau because of:
- Poor sleep
- Losing muscle mass, which can lower your metabolic rate, and can happen if you aren’t exercising much, especially if you are taking GLP-1 medications
- Hormonal changes, like the ones you may experience during menopause
- Inflammation that comes from fat stored by your body
Signs you’re in a weight loss plateau
You may be in a plateau if:
- You’re following your plan but not seeing progress
- Your weight has stayed the same for three to four weeks or moved up and down a few pounds with no consistency
- Your clothes fit the same way
- Your hip, waist and arm measurements haven’t changed
- Your body fat percentage hasn’t changed
Even though plateaus are frustrating, they are normal and temporary. They mean your body needs a new challenge.
Ways to overcome a weight loss plateau
These strategies can help restart your weight loss.
1. Revisit your eating habits
“Calories can slowly creep up when you become too comfortable with your daily routine,” Valles said. “When you’re in a stall, you should track everything you consume, including drinks, snacks, cooking oils and sauces, for one to two weeks.”
These small shifts can make a difference:
- Check portion sizes
- Add lean protein to maintain or rebuild muscle mass, especially if you’re taking a GLP-1 medication
- Focus on whole foods and fiber
- Limit added sugars and refined snacks
2. Increase physical activity
Moving more throughout the day helps you burn more calories. Try:
- Adding more daily steps
- Increasing how long or how intensely you exercise
- Including interval training for variety
3. Add strength training
Strength training is one of the best ways to break a plateau, since muscles can burn more calories at rest than fat. Aim for strength training two to four days per week. Building or maintaining muscle mass helps:
- Boost your metabolism
- Improve your function
- Support long-term weight management
4. Get the sleep you need
“Poor sleeping habits can affect weight loss,” Valles said. “Sleep is a key factor in both metabolic health and fitness progress.”
It can help to:
- Aim for seven to nine hours of quality rest each night
- Keep consistent sleep and wake times
- Make sure your sleep space is dark and cool
- Limit screen use one to two hours before bed
5. Change your routine
Your body adjusts to habits and routines. Trying new exercises or shifting your schedule can stimulate new progress.
6. Manage stress
“Chronic stress raises cortisol, which can make your body store more fat, especially in the belly area. It can also drive stress-related eating that undermines your goals and it may cause water retention that masks true fat loss on the scale,” Valles said.
Try to manage stress with daily meditation or mindfulness, deep breathing, regular physical activity like walking or yoga, journaling or therapy and maintaining strong social connections.
7. Consider metabolic testing
You can find metabolic tests at hospital wellness centers, sports performance facilities, weight loss clinics and some gyms. These tests can include:
- Resting metabolic rate (RMR) to measure the calories you burn at rest
- DEXA scans for detailed body composition
- Comprehensive metabolic panels that check thyroid function and glucose regulation
- Hormone testing for cortisol and sex hormones
“These assessments give you a more accurate baseline for the calories you need, help identify metabolic or hormonal issues and track changes beyond scale weight. They are especially useful after four to six weeks of a true plateau,” Valles said.
Other factors that can affect weight loss
Other circumstances can also affect your results, including:
- Hormone changes
- Certain medications
- Health conditions like thyroid disorders
If you’re doing everything right but your body isn’t responding, it may be time to check in with your health care provider.
GLP-1 medications and weight-loss plateaus
GLP-1 medications such as semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) are now common tools for helping people lose weight. These medicines help lower your appetite, make you feel full and stabilize your blood sugar.
“Weight loss plateaus are normal and can also happen to those using GLP-1 medications,” Valles said. Plateaus don’t mean the medication isn’t working. They can be a sign that your body is adjusting to a lower weight and changes in food and activity.
- Over time, your body may get used to the effect of GLP-1s and you may feel hungrier. “Early on, people on GLP-1 medications often eat much less but as the body adapts, portion sizes may slowly increase without noticing,” Valles said.
- Your body may adjust to eating fewer calories by slowing how many calories it burns, called metabolic adaptation.
- Losing muscle along with fat can slow your metabolism and make fat loss harder. That’s why meeting protein goals is important.
- Lower energy from not eating enough calories or other essential nutrients can lead to less movement during the day. It may help to eat small, regular meals instead of large meals.
- GLP-1 medications can change the foods you want or crave. “Many people prefer lighter foods and lose interest in greasy or sugary foods and drinks. This can help with weight loss but it can also make it harder to eat enough, especially protein,” Valles said.
You may need to adjust your treatment plan or add strength training or more physical activity. Personalized nutrition guidance may also help.
“Weight loss is a journey. GLP-1 medications can be a safe and effective tool to help with weight loss, with the support of your health care team. They have given many people hope after years of struggling to lose weight,” Valles said.
However, GLP-1 medications aren’t right for everyone. And if you take them, you need medical evaluation and monitoring. Your health care provider can help you figure out whether medication, lifestyle changes or bariatric services will help you meet your goals and give you the most health benefit.
When to seek medical or bariatric support
It may be time to talk with a provider if:
- Your weight loss plateau lasts more than four to six weeks, even though you’re following your medication, nutrition and exercise plan
- You have extreme fatigue, hair loss, weakness or muscle loss, which could be signs of nutritional or hormonal concerns
- Your hunger suddenly returns strongly or your weight increases
- You’re not sure about adjusting your calories or protein intake
- You may benefit from GLP-1 therapy, medication review or other weight loss treatments
- You have new or worsening side effects while taking a GLP-1 medication, such as ongoing nausea, vomiting, dizziness or trouble eating enough
- Your weight is affecting your health or daily life
Health benefits beyond the scale
Progress isn’t only about weight. Even when the scale pauses, your health can still improve.
Improved activity, better nutrition and increased physical activity can help:
- Lower your blood pressure
- Increase your strength
- Boost your energy
- Improve your mood
