Introduction
The problem of overweight and obesity is especially acute today. According to the World Health Organization, the number of people with excess body weight and obesity continues to rise worldwide, affecting not only adults but also children. Excess weight is not just an aesthetic issue, but a serious health risk factor: it increases the likelihood of developing cardiovascular diseases, type 2 diabetes, hypertension, joint diseases, certain types of cancer, and other chronic illnesses.
Weight loss is a complex process that includes changing eating habits, increasing physical activity, addressing psychological aspects, and, if necessary, medical supervision. In this article, we will review the main scientific principles of weight loss, modern approaches to reducing weight, common mistakes, and provide practical recommendations for those who have decided to change their lives and become healthier.
1. The Physiology of Weight Loss: How the Body Loses Weight
Weight loss occurs when the body expends more energy than it receives from food. This difference between incoming and outgoing calories is called an energy deficit. When the body does not receive enough energy from food, it begins to use internal reserves, primarily fat tissue.
Main components of energy expenditure:
Basal metabolic rate (BMR): the amount of energy required to maintain vital functions at rest (breathing, heart function, maintaining body temperature, etc.)
Physical activity: any movement, including sports, walking, housework, etc.
Thermogenesis of food: energy spent on digesting, absorbing, and assimilating food
To lose weight effectively, it is important to create a moderate calorie deficit (usually 10–20 percent of the daily norm) so that the process is gradual and safe for health.
2. Nutrition for Weight Loss: What and How to Eat
Nutrition is a key factor in the weight loss process. There are many diets promising quick results, but scientific research shows that the main thing is not a specific diet, but the overall energy balance and the quality of the diet.
2.1. Calorie Deficit
To lose weight, you need to create a calorie deficit. This can be done in two ways: reduce the caloric content of your diet or increase physical activity. The optimal reduction is considered to be 300–500 kcal per day, which will lead to a loss of 0.5–1 kg per week.
2.2. Diet Composition
Proteins are necessary to preserve muscle mass, especially during weight loss. It is recommended to consume 1.2–2 g of protein per 1 kg of body weight per day. Sources: meat, fish, eggs, dairy products, legumes.
Fats should not be completely excluded from the diet. Healthy fats (vegetable oils, nuts, avocado, fish) are necessary for hormone function and vitamin absorption.
Carbohydrates are the main source of energy. Preference should be given to complex carbohydrates: whole grains, vegetables, fruits.
2.3. Meal Frequency and Regimen
Frequent small meals help control appetite and blood sugar levels. However, studies show that the main thing is the total daily caloric intake, not the number of meals.
2.4. Water
Adequate water intake is important for metabolism and the removal of fat breakdown products. It is recommended to drink at least 1.5–2 liters of water per day.
2.5. Restrictions and Mindfulness
Minimize the consumption of sugar, sweet drinks, pastries, fast food, and processed foods.
Include more vegetables, greens, fruits, and whole grains in your diet.
Watch portion sizes and try to eat slowly to feel fullness in time.

Breakfast: omelet with vegetables, whole grain bread, tea
Lunch: chicken breast, buckwheat, salad

3. Physical Activity: Why It’s Needed for Weight Loss
Physical activity not only speeds up the weight loss process but also improves overall health, mood, sleep quality, and reduces the risk of chronic diseases.
3.1. Aerobic Exercise
Cardio (running, walking, swimming, cycling, dancing) helps burn calories and strengthens the cardiovascular system. It is recommended to do at least 150 minutes of aerobic exercise per week.
3.2. Strength Training
Strength exercises (bodyweight training, gym machines, dumbbells) help preserve and increase muscle mass, which is especially important during weight loss. Muscles burn more energy even at rest, so their development helps speed up metabolism.
3.3. Everyday Activity
Do not underestimate the role of regular physical activity: walking, climbing stairs, housework, playing with children, etc. All of this together significantly increases energy expenditure.
3.4. Sample Beginner Exercise Routine
1. Squats — 3 sets of 15 reps
2. Push-ups (regular or on knees) — 3 sets of 10 reps
3. Plank — 3 sets of 30 seconds
4. Lunges — 3 sets of 12 reps per leg
5. Crunches — 3 sets of 15 reps
6. Jumping in place or with a rope — 3 sets of 1 minute
Exercise 3–4 times a week, gradually increasing the load.
4. The Psychology of Weight Loss: How Not to Give Up and Achieve Results
Weight loss is not only a physical but also a psychological process. Many face difficulties: breakdowns, loss of motivation, guilt over "wrong" food. Here are some tips to make the journey more comfortable:
4.1. Set Realistic Goals
A safe rate of weight loss is 0.5–1 kg per week. Do not expect instant results or compare yourself to others. Every body is individual.
4.2. Keep a Food and Activity Diary
Write down what and how much you eat, how much you move. This helps identify "weak spots" and control the process.
4.3. Don’t Blame Yourself for Setbacks
Sometimes there are holidays, meetings with friends, stressful situations. It is important not to scold yourself, but simply return to healthy habits.
4.4. Seek Support
Share your successes with loved ones, find like-minded people, join themed groups. Support and sharing experiences are very important.
4.5. Work with the Causes of Overeating
Often, excess weight is associated with emotional overeating, the habit of "eating" stress, boredom, fatigue. It is important to learn to recognize your emotions and find other ways to cope with them.
4.6. Psychological Techniques
Emotion diary: write down what you feel before eating to identify overeating triggers.
Meditation and breathing exercises: help reduce stress and anxiety.
Visualization of the goal: imagine yourself having achieved the desired result, it helps maintain motivation.
Positive affirmations: form a positive attitude towards yourself and your body.
5. Medical Aspects of Weight Loss
Before starting any weight loss program, it is recommended to consult a doctor, especially if you have chronic diseases, hormonal disorders, heart or joint problems.
5.1. Medication
In some cases, a doctor may prescribe weight loss medications, but they are used only under strict indications and medical supervision.
5.2. Surgical Methods
Bariatric surgery (reducing stomach volume, bypass surgery) is used for severe obesity when other methods are ineffective. This is a serious intervention requiring long-term follow-up.
5.3. Tests and Examinations
Before starting weight loss, it is advisable to do basic tests: complete blood count, biochemistry, thyroid hormones, glucose, lipid profile. This will help identify possible causes of weight gain and adjust the program.
5.4. The Effect of Hormones on Weight
Hormonal disorders (e.g., hypothyroidism, insulin resistance, polycystic ovary syndrome) can make weight loss difficult. It is important to identify and correct such conditions in time.
6. Common Mistakes in Weight Loss
6.1. Overly Strict Diets
Extreme calorie restrictions lead to slowed metabolism, loss of muscle, poor well-being, and breakdowns.
6.2. Avoiding Fats
Fats are necessary for hormone function, vitamin absorption, and skin health. Complete avoidance of fats is harmful.
6.3. Expecting Quick Results
Rapid weight loss often ends with quick weight regain (yo-yo effect). It's better to lose weight slowly but steadily.
6.4. Using "Miracle Remedies"
Supplements, slimming teas, fat burners have no proven effectiveness and can be dangerous to health.
6.5. Ignoring Physical Activity
Diet alone without physical activity leads to muscle loss and slowed metabolism.
6.6. Skipping Meals
Long breaks between meals can lead to overeating at the next meal.
7. Weight Loss Myths
7.1. You Can Lose Weight Only in One Area
Local fat burning is impossible, the body loses fat evenly.
7.2. Late Dinners Prevent Weight Loss
The main thing is total daily caloric intake, not the time of meals.
7.3. Fasting is the Best Way to Lose Weight
Fasting can lead to muscle loss, metabolic disorders, and health problems.
7.4. Detox Diets Cleanse the Body
The liver and kidneys do an excellent job of cleansing the body without special diets.
7.5. The More You Train, the Faster You Lose Weight
Excessive exercise can lead to injuries and burnout. It is important to balance workouts and rest.
