If obesity were only about willpower and food choices, we would have solved it a long time ago. Yet, the narrative that obesity is all about “eating too much and not moving enough” still dominates public debate. While diet and physical activity matter, they only represent one piece of a much bigger and complex puzzle.
Biology says something different. Obesity is now recognized as a chronic medical condition, not a lack of self-control or a personal failure. It is influenced by a combination of multiple factors such as metabolism, genetics, environment, hormones, psychology, and even past weight-loss attempts. These mechanisms can actively work against the body’s ability to lose or maintain weight.
Because of its complexity, obesity oftentimes requires more than just lifestyle tips. In many cases, a medical approach combined with sustainable and personalized lifestyle strategies, is necessary to support long-term health.
To move away from blame and get a better understanding of obesity, we need to look beyond calories and diet, and explore the hidden lifestyle and biological factors that shape how the body regulates weight.
The body & stress
Regardless of our weight or lifestyle, we all experience stress. It’s part of being human and, to some extent, it’s unavoidable. But what exactly is stress?
Stress is the body’s natural response to change or challenge. Not all stress is harmful. Some forms of stress are positive, the kind that makes you feel motivated, energized, or excited. Think about starting a new job, going on a first date, or learning a new skill. This type of stress is usually short-lived and can even be beneficial.
The problem arises when stress becomes constant. Chronic stress, such as ongoing financial pressure, job insecurity, or relationship difficulties, keeps the body in a prolonged state of alert. Over time, this persistent stress leads to elevated levels of cortisol, often referred to as the body’s main stress hormone.
High cortisol levels don’t just affect how we feel emotionally, they directly impact our physiology. Cortisol influences appetite, energy levels, mood, sleep, and how the body stores fat. When cortisol remains elevated for long periods, it can increase hunger, promote cravings for unhealthy and convenient foods, and disrupt normal eating patterns.
Even more importantly, chronic stress affects where fat is stored in the body. Elevated cortisol is strongly associated with increased fat accumulation in the abdominal area, a region that is particularly linked to metabolic complications. This type of fat distribution is associated with a higher risk of conditions such as type 2 diabetes and cardiovascular disease.
In other words, obesity is not only about how much fat the body carries, but also where it stores it, and stress plays a major role in that process.
Sleep: The silent regulator
Sleep is often the first thing we sacrifice when life gets busy, yet it is one of the most powerful regulators of body weight and metabolic health. Just like stress, poor sleep doesn’t affect only how tired you feel the next day, it affects how your body functions at a hormonal and physiological level.
When you don’t get enough sleep, your body enters a state of imbalance. Two key hormones that regulate appetite are directly affected, ghrelin, the hormone that stimulates hunger, increases, while leptin, the hormone that signals fullness, decreases. In simple terms, lack of sleep makes you hungrier and less satisfied after eating. This explains why short nights are often followed by stronger cravings, larger portions, and a tendency to snack more, especially on high-calorie, sugary or salty foods.
Poor sleep also worsens insulin sensitivity, meaning your body has a harder time managing blood sugar levels. Over time, this can promote fat storage, particularly in the abdominal area, and increase the risk of metabolic conditions such as type 2 diabetes. Combined with elevated cortisol levels from chronic stress, sleep deprivation creates a hormonal environment that actively works against weight regulation.
Beyond hormones, fatigue affects behavior. When you are exhausted, decision-making becomes harder. You are less likely to cook balanced meals, more likely to rely on convenience foods, and less inclined to move your body. Physical activity feels more demanding, recovery is slower, and motivation drops. This creates a cycle where poor sleep leads to behaviors that further impair sleep quality and metabolic health.
So sleep is a biological necessity. Improving sleep duration and quality doesn’t just support weight management, it supports hormonal balance, energy levels, mental health, and overall well-being.
Movement is not a punishment
Movement is often reduced to one thing, burning calories. But this limited view misses its real power. Movement is not a punishment for what you ate. It is a cycle breaker. Regular movement, whether it’s walking, mobility work, or resistance training, plays a central role in regulating your metabolism. It helps your body use energy more efficiently, improves insulin sensitivity, stabilizes blood sugar levels, and supports fat metabolism. In other words, movement helps your body work with you, not against you.
But the benefits go far beyond physiology. Movement is one of the most effective tools we have to manage stress. It lowers cortisol levels, improves mood, and supports better sleep. Even low-intensity movement like walking can significantly reduce stress and improve mental clarity.
Another key benefit of movement is its impact on body composition. Rather than focusing only on the number on the scale, movement helps increase muscle mass, preserve lean tissue, and reduce fat mass over time. This shift improves metabolic health, strength, and resilience, regardless of weight loss.
What matters most is consistency, not intensity. You don’t need extreme workouts to see results. Sustainable, enjoyable movement practiced regularly is far more effective than short bursts of high-intensity effort followed by long periods of inactivity.
Beyond the physical, movement reconnects you to yourself. It builds confidence, restores trust in your body, and allows you to rediscover what your body is capable of. For many people, it becomes a gateway to improved mental well-being, self-awareness, and even a renewed sense of identity.
Environment & lifestyle
Finally, we need to talk about environment and lifestyle, not as excuses, but as real and powerful influences on our health.
Most people don’t live in a vacuum where they can perfectly plan meals, train daily, sleep eight hours, and manage stress effortlessly. Real life looks like busy schedules, long workdays, commuting, academic pressure, financial stress, family responsibilities, and emotional load. When your days are packed, and your energy is constantly drained, healthy choices become harder, not because you don’t care, but because you’re exhausted.
A lack of structure often leads to irregular meals, skipped meals, followed by overeating, reliance on convenience foods, and eating driven by emotions rather than hunger. Emotional eating, in particular, is not a lack of discipline, it’s a coping mechanism. Food can become a source of comfort, relief, or control in an environment that feels overwhelming or unpredictable.
Mental health also plays a major role. Anxiety, low mood, chronic stress, or burnout can significantly impact appetite, motivation to move, sleep quality, and even how connected you feel to your body. When mental health is struggling, expecting “perfect” lifestyle habits is unrealistic and unfair.
Our environment shapes our behaviors, our rhythms, and our capacity to care for ourselves. Sustainable health improvements don’t come from shame or extreme rules, but come from creating supportive routines, realistic structures, and an environment that makes healthy choices easier, not harder.
Reframing obesity
Obesity is a complex and multifactorial condition that cannot be reduced to individual choices alone. Sustainable health improvements do not come from shame, restriction, or extreme rules. They come from small, consistent habits, supportive routines, realistic goals, and environments that make healthy choices easier, not harder.
Sometimes, the most powerful thing you can do for your health is not to do more, but to simplify. To slow down. To listen to your body. To rebuild habits that fit your real life, with kindness rather than pressure. If there is one takeaway, let it be this, health is not about perfection, it’s about creating a lifestyle that works with your biology, not against it.
