Maybe the problem isn’t that you’re not trying hard enough.
“I am doing everything right. I am eating less. I am exercising. I am walking. I have stopped sugar. But why am I still not losing weight?”
I hear this question again and again. And usually, the person asking it is already trying very hard. They are checking the weighing scale, counting what they eat, adding more workouts, cutting out foods they enjoy and wondering what else they are supposed to do.
So before you decide that you are lazy, undisciplined or simply not trying hard enough, I want you to understand something important: weight loss is not just a matter of willpower. Your body is constantly trying to regulate energy, appetite, temperature, blood sugar and many other internal processes. When your weight changes, those systems can change too.
Your body is not just a calculator
We often think about weight loss as a simple calculation: eat fewer calories, burn more calories, and the scale should keep moving down. Energy balance absolutely matters, but the human body is much more dynamic than a calculator.
When you lose weight, your body can respond by increasing hunger and reducing the amount of energy it uses. Research from the National Institute of Diabetes and Digestive and Kidney Diseases describes these adaptations as part of the physiology of the weight-reduced state. In other words, the body can push back against continued weight loss, which is one reason maintaining weight loss can be difficult.
One NIDDK research update found that appetite increased as people lost weight, contributing to a slowing or leveling off of weight loss. This does not mean your body is “working against you” in some simple or personal way. It means your biology is responding to a change in energy availability.
This is where homeostasis comes in
Your body likes stability. This general principle is called homeostasis. It does not mean there is one fixed weight that your body will always force you back to, because body weight is influenced by physiology, genetics, environment, behaviour and many other factors. But your body does have regulatory systems that help control appetite and energy expenditure. That is why the first few weeks of a diet can sometimes feel exciting. You are doing the same things and the scale is moving. Then, after some time, progress slows. Hunger may become stronger. You may feel less energetic. The same workout may not burn exactly what it used to. And suddenly you think, “What am I doing wrong?”
Now let’s talk about stress, because this part is often ignored
You can have a good food plan and a decent exercise routine, but if your life is constantly stressful, your weight-loss journey can become much harder to manage.
When you experience stress, your brain activates the hypothalamic-pituitary-adrenal, or HPA, axis. In simple terms, the hypothalamus signals the pituitary, the pituitary signals the adrenal glands, and the adrenal glands release cortisol. Cortisol is not a bad hormone. You need it for normal stress responses, energy metabolism and many other functions.
The problem is not that cortisol exists. The problem is that long-term stress can affect the wider system around weight management. Stress can influence appetite, cravings, sleep, emotional eating, daily movement and recovery. Research has also linked chronic stress and altered HPA-axis activity with obesity, particularly abdominal fat, although the relationship is complex and not the same for everyone.
So I would not tell you, “You have high cortisol, therefore you cannot lose weight.” That is too simplistic. And I would not tell you that everyone under chronic stress becomes “cortisol resistant.” Glucocorticoid sensitivity can vary between people and tissues, but the science is much more complicated than an Instagram reel usually makes it sound.
Sometimes the scale is telling you less than you think
This is another reason I do not want you to make the weighing scale the judge of your entire journey.
Your body weight can move from day to day because of water, the amount of food still in your digestive system, salt and carbohydrate intake, hormonal fluctuations and changes in activity. You can have a perfectly good week and still see the scale go up temporarily. That does not automatically mean you gained body fat. If you weigh yourself every day, look at the trend rather than reacting emotionally to one number. And also pay attention to things the scale cannot show you: your waist measurement, how your clothes fit, your strength, your energy, your fitness and how consistently you are following your routine.
So what should you actually do?
First, stop assuming that harder always means better. If your plan is so aggressive that you are constantly hungry, exhausted, stressed and thinking about food, it may be time to rethink the plan rather than simply adding more punishment.
Build your routine around food you can realistically continue eating, regular physical activity, strength training, enough sleep and recovery. You still need an appropriate energy deficit for fat loss, but the way you create that deficit matters because a plan that you cannot maintain is not a very useful plan. And please remember that weight is affected by more than food and exercise. Sleep, medicines, health conditions, genetics and your daily environment can all play a role. If your weight is changing unexpectedly or you are struggling despite consistent efforts, it is worth discussing the situation with a qualified healthcare professional rather than blaming yourself.
The goal is not to deceive your body. It is to understand it.
This is the part I want you to remember. You do not need to spend your life trying to trick your body into losing weight. You need to understand how your body responds and build a routine that works with those responses instead of constantly fighting them.
If you have been trying very hard and the scale has stopped moving, do not immediately conclude that you have failed. Look at the whole picture. Look at your food. Look at your activity. Look at your sleep. Look at your stress. Look at your recovery. Look at the trend over time. And then decide what actually needs to change. Weight loss is not just about making yourself eat less and exercise more. It is about creating a system you can live with.
Research Corner
The National Institute of Diabetes and Digestive and Kidney Diseases explains that physiological adaptations after weight loss can reduce energy expenditure and increase energy intake, making weight-loss maintenance difficult.
NIDDK research has also found that appetite can rise as weight is lost, contributing to a leveling off of weight loss. NIDDK notes that weight is influenced by lifestyle, sleep, medicines, health conditions, family history and genes, and that metabolism and hormonal changes can make maintaining weight loss difficult.
