If you have any medical questions or concerns, please talk to your healthcare provider. The articles on Health Guide are underpinned by peer-reviewed research and information drawn from medical societies and governmental agencies. However, they are not a substitute for professional medical advice, diagnosis, or treatment.

If you’ve lost weight only to put it all back on again (and maybe even a little more), you’re not alone. While losing weight is hard, keeping it off can be even more difficult, with research showing only about 20% of people will maintain their weight loss in the long term.

Fortunately, this doesn’t mean you’re destined to regain lost weight. There are steps you can take to preserve the weight you’ve worked hard to achieve. Before discussing them, it’s helpful to understand some common pitfalls people fall into after dieting, and how healthy habits can help you maintain a healthy weight for life.

Why can’t I keep the weight off?

There are two main reasons why people tend to put weight back on after losing it.

Your body is wired to keep you at a certain weight

The human body is programmed to function within specific limits. For example, your body temperature needs to stay at approximately 37° Celsius and prolonged exposure to extreme temperatures can have serious effects on your health. This state of balance, and the body’s efforts to maintain it, is known as ‘homeostasis’.

Weight Set Point

When it comes to weight, starvation is more of an immediate survival threat than obesity, so homeostasis causes us to favour preserving energy stores (fat) over staying lean. Research also suggests that your body has a weight ‘set point’. This means your body will fight to go back to your old weight, which drives subconscious behaviours such as hunger and overeating.

Hormones and subconscious eating

Your hormones play a key role in these subconscious eating behaviours, with research showing weight loss is linked to hormonal changes that make it more difficult to keep lost weight off.

Going back to old habits after hitting your weight goals 

Another reason it can be hard to sustain weight loss is the tendency to return to old patterns – which caused you to gain weight in the first place – after reaching your desired weight. Examples include:

  • Eating too many kilojoule - dense, nutrient-poor foods – such as fatty or sugary snacks or soft drinks
  • Drinking too much alcohol – alcohol is very high in kilojoules, which makes it easy to consume more energy than you need from drinking
  • Eating out – if you lost weight by restricting take-aways or social dining, resuming these activities could cause you to put it back on
  • Emotional eating – failure to address the underlying issues could lead you back into old ways of coping
  • Oversized portions – which can lead to consuming more kilojoules than you need
  • Lack of physical activity – if you’ve taken up exercise to aid weight loss, going back to a sedentary lifestyle may lead to weight regain, especially if you combine that with unhealthy eating.

The 10 best tips for keeping weight off

Following these 10 strategies will boost your chances of being among the one in five people who successfully maintain their weight loss.

1. Treat any medical causes of weight gain

Some medical conditions (including polycystic ovary syndrome and underactive thyroid) are directly associated with weight gain, and others (including depression and diabetes) can lead to weight management issues. Certain medications (such as some medicines used to treat seizures and mental health disorders) can also cause weight gain.

Talk to your doctor

It can be extremely difficult to keep lost weight off if your body is grappling with a medical problem, so talk to your doctor about how your health or medications may be impacting your weight.

2. Ditch the diet mentality

While dieting can lead to weight loss, successful long term weight management is about making sustainable lifestyle changes. Rather than focusing on quick fixes like diets, concentrate on making choices that will help to keep you fit and healthy for the rest of your life.

3. Stay physically active

Exercise burns calories and can offset the energy you take in from food. Importantly, several studies have shown that regular physical activity can help you keep weight off after losing it. Exercise also has proven benefits for physical and mental health. Making it part of your lifestyle is not only a great way to keep your weight under control, but it will also pay off in a host of other ways.

Muscle tissue uses more energy than other tissues and resistance training has been shown to offset loss of lean muscle during weight loss, so be sure to include some resistance exercises in your routine – such as activities using dumbbells, bands or your body weight.

4. Develop a support network

If you haven’t already, gather a network of people who are committed to helping you maintain your weight loss around you. Give them permissions to keep you accountable for making healthy choices and getting you back on track after any lapses.

It’s also helpful to limit contact with anyone who tries to sabotage your success, such as people who try to lure you back into unhealthy habits.

5. Eat breakfast

Research has shown that people who have successfully maintained their weight loss commonly report eating breakfast. One study found that in men, breakfast consumption was positively associated with weight-loss maintenance, but more research is needed to confirm if eating breakfast was the cause of this success, and if this finding only applies to men.

6. Eat more protein

Eating protein has been linked with several benefits that may assist with weight maintenance, including helping you feel full, causing your body to burn more energy, and helping you to maintain lean muscle mass.

7. Stay well hydrated

Drinking water helps you feel full, and research has shown that drinking a glass or two before eating can lead to consuming fewer kilojoules. Drinking water has also been shown to raise your metabolic rate, which can cause you to burn more energy throughout the day.

8. Get enough sleep

Adequate sleep is vital for weight maintenance, with studies linking lack of sleep with obesity. This appears to be partly due to hormonal changes that lead to increased appetite and a reduced ability to feel full. Being tired may also reduce your motivation to exercise.

9. Track for success

Another great way to stay focused and sustain your weight loss is to track your progress. Research has shown that people who successfully keep weight off tend to check it frequently, so keep a set of scales handy and weigh yourself regularly.

Monitoring your eating is another great way to stay on target. Studies indicate that people who track their food intake in a journal or online app may be more aware of their eating patterns and more likely to sustain their weight loss.

10. See your healthcare practitioner regularly

Your healthcare provider can help you stay on track by monitoring your body mass index (BMI) and addressing any other issues that may be impacting your weight. Your doctor can also refer you to other health providers for support with weight maintenance, such as a clinical dietitian or accredited exercise physiologist.
