Always feeling like I'm not thin enough?


Hello, I am a girl transitioning from middle school to high school.
I am 160 cm tall and previously weighed 53 kg.
I am determined to lose weight and have now reduced my weight to between 45 and 46 kg.
However, my menstrual period has not come for over six months.
My period was quite regular after it first started in September last year, but it became irregular as I began losing weight.
I feel guilty whenever I eat and constantly think that I am not thin enough.
What should I do?

Currently, middle and high school girls often blindly pursue the slender beauty of models.
In reality, improper weight loss can lead to issues such as malnutrition, anorexia, and bulimia, with amenorrhea being one of the most common consequences.
For a height of 160 cm, the ideal weight is 56 kg, so 53 kg is considered acceptable.
Adolescence is a critical period for rapid growth and development, as well as for preparing for future pregnancy and overall health.
Instead of focusing on weight loss, it would be better to spend more time on physical exercise.

It's important to acknowledge that your journey towards weight loss and body image is a sensitive and complex issue, especially at your age. At 160 cm tall and weighing between 45-46 kg, you are at the lower end of the healthy weight range, which can vary based on factors like muscle mass and body composition. However, your experience of missing your period for over six months is concerning and indicates that your body may be under significant stress, likely due to your restrictive eating habits and possibly excessive exercise.

Firstly, it's crucial to understand that healthy weight loss should not come at the expense of your overall health. The absence of menstruation, known as amenorrhea, can be a sign of hormonal imbalance, often caused by inadequate nutrition, excessive exercise, or significant weight loss. This condition can lead to long-term health issues, including decreased bone density, which increases the risk of fractures, and potential fertility problems in the future.

Your feelings of guilt associated with eating and the constant comparison to others can create a negative cycle that is detrimental to your mental health. It's essential to shift your focus from weight alone to overall well-being. Here are some recommendations to help you navigate this journey more healthily:
1. Balanced Nutrition: Instead of restricting entire food groups, aim for a balanced diet that includes a variety of foods. This should consist of whole grains, lean proteins, healthy fats, fruits, and vegetables. A well-rounded diet will provide the necessary nutrients your body needs to function properly and can help regulate your menstrual cycle.

2. Mindful Eating: Practice mindful eating by paying attention to your hunger and fullness cues. Allow yourself to enjoy food without guilt. Remember that food is not just fuel; it can also be a source of pleasure and social connection.

3. Regular Exercise: While exercise is beneficial for weight management and overall health, it should be enjoyable and not excessive. Aim for a mix of aerobic activities (like walking, swimming, or cycling) and strength training, but ensure you are not overexerting yourself. The goal is to feel energized rather than fatigued.

4. Mental Health Support: Consider talking to a counselor or therapist who specializes in body image and eating disorders. They can provide support and strategies to help you develop a healthier relationship with food and your body.

5. Consult a Healthcare Professional: Given your missed periods and weight loss, it would be wise to consult a healthcare provider. They can assess your overall health, provide guidance on safe weight management, and help address any underlying issues related to your menstrual cycle.

6. Set Realistic Goals: Instead of focusing solely on a number on the scale, set goals that emphasize health and well-being. This could include improving your fitness level, trying new activities, or developing a positive body image.

Remember, your worth is not determined by your weight or appearance. Embrace your body and focus on nurturing it through healthy habits. It's essential to prioritize your health over societal pressures or comparisons with others. Your journey should be about feeling good, both physically and mentally, rather than just achieving a specific weight.
