Fluctuating weight?


I wonder if it's related to my personality, but whenever I experience high work stress, I have a strong urge to eat and find it hard to control my appetite.
Last year, during the busy season (about 3 to 4 months), I gained 10 kilograms, but I managed to lose that weight again during the off-season over 3 months through sheer willpower.
However, this year during the busy season, I found myself in the same situation and gained another 10 kilograms, which has been quite distressing for me.
Does this indicate that there might be an issue with my body? If so, should I consult a specialist in metabolic disorders? Additionally, I tend to get very anxious; when I'm nervous, I experience muscle tension and stiffness in my neck, and at my worst, I even feel nauseous.
I'm unsure if my fluctuating weight is a psychological issue affecting my physiology, or if I should see a psychiatrist.
This problem has been bothering me lately, and even though I want to see a doctor, I'm uncertain about which specialty to consult.
I hope to receive some guidance.
Thank you very much!

Hello, Miss: The principles of weight control are proper diet and appropriate exercise.
In terms of diet, it is important to maintain nutritional balance and avoid high-sugar and high-fat foods.
An ideal weight loss rate is about 2 kilograms per month, so losing 10 kilograms in three months is a bit too fast.
I recommend that you first consult an internist and have necessary blood tests done.

Your experience with weight fluctuations and the impact of stress on your eating habits is a common issue that many individuals face, particularly in high-pressure environments. The relationship between stress, metabolism, and mental health is complex and multifaceted, and understanding this interplay can help you develop strategies to manage your weight more effectively.

Firstly, it’s important to recognize that stress can significantly influence eating behaviors. When you experience stress, your body produces hormones such as cortisol and adrenaline. Elevated cortisol levels can lead to increased appetite and cravings for high-calorie foods, often referred to as "comfort foods." This is a biological response that dates back to our ancestors, where high-energy foods were essential for survival during stressful times. Unfortunately, in modern society, this can lead to overeating and weight gain, as you've experienced during your busy work periods.

Your pattern of gaining and losing weight—10 kilograms during busy seasons and then losing it during quieter times—suggests that your body is responding to external stressors rather than a consistent metabolic or physiological issue. However, it’s essential to consider that chronic stress can lead to metabolic changes over time, potentially affecting how your body processes food and stores fat. This is why consulting with a healthcare professional, such as an endocrinologist or a metabolic specialist, could be beneficial. They can evaluate your metabolic health and rule out any underlying conditions that may be contributing to your weight fluctuations.

Additionally, your description of feeling tense, having a stiff neck, and experiencing nausea when stressed indicates that your mental health is also a significant factor in this equation. Stress and anxiety can manifest physically, leading to discomfort and further complicating your relationship with food. It might be helpful to speak with a mental health professional, such as a psychologist or psychiatrist, who can help you develop coping strategies for managing stress and anxiety. Cognitive-behavioral therapy (CBT) is particularly effective for addressing emotional eating and can provide you with tools to better manage your responses to stress.

In terms of practical strategies, consider the following approaches to help manage your weight and stress:
1. Mindful Eating: Practice being present during meals. Pay attention to your hunger cues and try to eat slowly, savoring each bite. This can help you recognize when you are full and reduce the likelihood of overeating.

2. Stress Management Techniques: Incorporate relaxation techniques into your daily routine, such as deep breathing exercises, yoga, or meditation. These practices can help lower cortisol levels and improve your overall sense of well-being.

3. Regular Physical Activity: Engage in regular exercise that you enjoy. Physical activity can help reduce stress, improve mood, and regulate appetite. Aim for a mix of cardiovascular, strength, and flexibility exercises.

4. Balanced Nutrition: Focus on a balanced diet that includes whole foods, such as fruits, vegetables, lean proteins, and whole grains. Avoid keeping high-calorie snacks readily available, as this can trigger impulsive eating during stressful times.

5. Seek Support: Consider joining a support group or working with a registered dietitian who specializes in emotional eating. Having a support system can provide encouragement and accountability.

In conclusion, your weight fluctuations are likely influenced by a combination of stress, emotional factors, and possibly metabolic responses. Consulting with both a metabolic specialist and a mental health professional can provide a comprehensive approach to addressing your concerns. By implementing stress management techniques and mindful eating practices, you can work towards achieving a healthier relationship with food and your body. Remember, it’s a journey, and seeking help is a positive step towards better health.
