Guide to Understanding Obesity and Managing It Effectively

Guide to Understanding Obesity and Managing It Effectively
2 April, 2026

The topic of excess weight is difficult. Many face judgment, unsolicited advice, and guilt. But when weight reaches a critical point, it’s not a sign of self-indulgence or a lack of willpower. It’s a chronic condition. It requires a competent approach, not self-flagellation.

We’ll explore what obesity really is and show you the best obesity treatment.

What Is Obesity?

Among adults ages 40 to 59, obesity prevalence is 46.4%. Excess fat places enormous strain on internal organs and disrupts their function. It leads to the development of dangerous diseases. Obesity occurs in adults and children. It is always the result of a complex interplay of genetics, lifestyle, stress, and so on.

How Do Doctors Make a Diagnosis?

For an initial diagnosis, doctors use the body mass index. This parameter represents the ratio of a person’s height to their weight. BMI does not directly measure body fat percentage. But it helps quickly assess the extent of the problem.

Category BMI
Normal weight 18.5 – 24.9
Overweight 25 – 29.9
Obesity Class 1 30 – 34.9
Obesity Class 2 35 – 39.9
Obesity Class 3 (Morbid) 40 and above

However, a good specialist never makes a diagnosis based solely on BMI. They also examine the patient’s waist circumference, which reveals the amount of dangerous visceral fat around the organs. The doctor then diagnoses any underlying conditions (such as diabetes or hypertension) and assesses the patient’s overall well-being.

The Main Causes of Obesity

Obesity never occurs for a single reason. It’s a puzzle made up of many pieces.

Genetics

Genes do matter. Research shows that heredity can determine up to 80% of predisposition to obesity. Genes influence:

  • how our body stores and breaks down fat;
  • how strong our appetite is and how quickly we feel full;
  • how quickly we burn calories at rest.

Having these genes isn’t a death sentence. But it does explain why some people can eat whatever they want without gaining weight, while others have to restrict themselves just to maintain their weight severely. It’s unfair, but it’s a reality we need to work with, not blame ourselves.

Metabolism

Metabolism is the rate at which the body converts food into energy. Some people burn calories faster than others, while others have a more difficult time. When a person loses weight, metabolism tends to slow down. The body thinks it’s time for a famine and begins conserving energy. This is why diets often plateau. Weight loss stops, even though you’re eating less. But as soon as you return to a normal diet, your body panics and begins storing fat even more actively.

Psychology

Food isn’t just fuel. It’s a pleasure, comfort, a way to cope with stress, a reward. Psychological problems, anxiety, low self-esteem, and depression influence eating behavior. Research confirms that obese people have a 55% higher risk of developing depression. Excess weight can be a consequence of psychological difficulties and their cause. Therefore, proper treatment always involves working not only on the body but also on the mind.

Environment

We live in a world literally designed for weight gain. We are surrounded by:
Available, high-calorie foods. Fast food, sweets, and processed foods are cheap and sold on every corner.

  • Sedentary work. Offices, remote work, studying… We spend hours without leaving our chairs.
  • Urban environment. Not everywhere are there parks or bike paths suitable for walking.
  • Cultural traditions. Food is at the center of any celebration or gathering.

In such conditions, fighting excess weight with willpower alone is very difficult. It is necessary to change your entire lifestyle.

Hormones and Medications

Sometimes, excess weight is caused by problems in the body:

  • People with hypothyroidism, polycystic ovary syndrome, and insulin resistance are prone to weight gain.
  • Some antidepressants, steroids, and beta-blockers can cause significant weight gain as a side effect.

Sleep

Lack of quality sleep disrupts hormonal balance. Levels of the hunger hormone ghrelin increase, while levels of the satiety hormone leptin decrease. As a result, you wake up unrefreshed and hungry. You crave high-calorie foods: sweets, fatty foods, and starchy foods. If you want to lose weight, you should establish a regular sleep-wake cycle.

What Are the Dangers of Obesity?

Obesity increases the risk of developing other serious diseases. Excess fat puts pressure on organs, disrupts metabolism, and causes chronic inflammation in the body.

Here are just a few of the risks:

  • Obesity provokes: Cardiovascular diseases include hypertension, high cholesterol, heart attacks, and strokes.
  • Obesity is a major risk factor for type 2 diabetes.
  • Obesity increases the risk of colon cancer, breast cancer (postmenopausal), kidney cancer, and liver cancer. Osteoarthritis of the knee and hip joints occurs due to the constant strain of excess weight.
  • Sleep apnea, or cessation of breathing during sleep, prevents sleep and is dangerous for the heart.
  • Fatty liver disease.

Good news! Even a small weight loss (5-10% of baseline) significantly reduces these risks and improves well-being.

Why Do Diets and Exercise Often Fail?

“Eat less and move more” is the foundation of a healthy lifestyle. But treating obesity as a chronic disease is often insufficient. Why? The weight loss is short-lived. Then it comes back. The body adapts to a calorie deficit and begins to expend less energy. Relapses are inevitable. Consider individual variability. What helped your friend lose weight may not work for you. Also, the diet doesn’t cure insulin resistance, doesn’t change genetics, and doesn’t address psychological trauma. These sometimes lead to weight gain. Look for a different approach. A competent doctor will help you with this.

Weight Management Strategies

Obesity treatment requires a team effort. Here are the building blocks of a successful strategy.

1. Healthy Eating

The basis of the diet is vegetables, fruits, lean meat, fish, eggs, and whole grains. They provide energy and keep you full for a long time. Eliminate fast food, sugary drinks, sausages, hot dogs, and snacks. They offer zero nutrition and a ton of empty calories. Eat slowly, without your phone, listen to your hunger and fullness signals.

2. Enjoy Physical Activity

Start small. Doctors often recommend cardio for weight loss. The World Health Organization recommends at least 150 minutes of moderate activity per week. That’s just 20-25 minutes a day. Walking, swimming, cycling. Find your favorite sport. Perhaps you’ll enjoy dancing, yoga, Pilates, Nordic walking, or team sports. Move more in your daily life! Take the stairs, get off a bus stop early, or go for a lunchtime walk.

3. Psychological Support

Work with a psychologist or psychotherapist to distinguish between physical and emotional hunger. Find ways to cope with stress that don’t involve food. A psychologist can also help you address issues with self-esteem and body image.

4. Medication Therapy

Some medications help control appetite and food cravings. Doctors prescribe them based on your specific situation. Medications are only effective when combined with lifestyle changes.

5. Bariatric Surgery

This is the most effective method for people with severe obesity and when other treatments have failed. Bariatric surgery alters hormonal balance and helps maintain weight for years.

Types of Surgery

In sleeve gastrectomy, the doctor removes a large portion of the stomach, forming a narrow tube from the remaining portion. This prevents the person from physically eating much. With gastric bypass, the doctor creates a small stomach and diverts food around part of the small intestine. This reduces calorie absorption and alters the release of hunger hormones.

Gastric banding involves placing a ring around the stomach to regulate the rate at which food passes through. A study showed that 12 years after surgery, patients maintained an average weight loss of 27% of their initial weight. In the group treated only with diet and exercise, the result was close to zero.

When Should You See a Doctor?

If you’ve repeatedly tried to lose weight on your own, but the weight keeps coming back, or if you have underlying medical conditions, it’s time to seek professional help.

A doctor can:

  • Conduct a complete hormone assessment, blood tests, etc.
  • Identify underlying causes interfering with weight loss.
  • Develop a personalized treatment plan.
  • Suggest the most appropriate methods.
  • Support you throughout the process.

A specialist will develop a weight management program tailored to you.
