Understanding weight fluctuations and body shape can be quite complex, especially when considering factors such as body fat distribution, muscle mass, and overall health. Your experience of fluctuating weight—losing and gaining over the years—is not uncommon. Many individuals face similar challenges, and it can be influenced by various factors including diet, exercise, hormonal changes, and even genetics.

Firstly, it’s important to recognize that weight alone does not provide a complete picture of health. Body composition, which includes the ratio of fat to muscle, is crucial. For instance, someone may weigh more due to increased muscle mass, which is denser than fat. This is often seen in athletes or individuals who engage in strength training. Conversely, someone may have a lower weight but a higher body fat percentage, which can be a concern for health.

In your case, the fact that you have experienced weight fluctuations from 65 kg to 52 kg and back up to 62 kg indicates that your body is responding to changes in your lifestyle, diet, and possibly stress levels. The persistence of fat in specific areas, such as the abdomen, can be attributed to several factors.
1. Genetics: Genetics play a significant role in where fat is stored in the body. Some individuals may find that they store fat more in the abdominal area, while others may store it in the hips or thighs. This is often referred to as body shape, which can be categorized into apple-shaped (more fat around the abdomen) or pear-shaped (more fat around the hips and thighs).

2. Hormonal Factors: Hormones can significantly influence fat distribution. For instance, estrogen tends to promote fat storage in the hips and thighs, while testosterone can lead to fat accumulation in the abdominal area. Changes in hormone levels, particularly during puberty, menstruation, pregnancy, or menopause, can affect how and where fat is stored.

3. Diet and Exercise: The types of food you consume and your level of physical activity can also impact body composition. A diet high in processed foods and sugars can lead to increased fat storage, particularly in the abdominal area. Regular exercise, especially strength training and cardiovascular activities, can help reduce body fat and improve muscle tone.

4. Stress and Sleep: Chronic stress and lack of sleep can lead to hormonal imbalances that promote fat storage, particularly in the abdominal area. Cortisol, a hormone released during stress, has been linked to increased abdominal fat.

Regarding your specific concern about the appearance of your abdomen, it’s essential to understand that body shape can vary widely among individuals. The presence of "double layers" of fat, as you described, may be due to the way your body stores fat and muscle. If you have concerns about your abdominal shape or if you suspect any underlying health issues, such as potential gastrointestinal or gynecological problems, it would be advisable to consult a healthcare professional. They can conduct a thorough evaluation, which may include physical examinations and imaging studies if necessary.

In conclusion, fluctuations in weight and body shape are normal, but understanding the underlying factors can help you manage your health better. Focus on a balanced diet, regular exercise, and stress management to help achieve your desired body composition. If you have persistent concerns about your body shape or health, seeking advice from a healthcare provider or a registered dietitian can provide personalized guidance and support.
