Understanding metabolism changes and dietary concerns is crucial for maintaining overall health, especially as we age or undergo lifestyle changes. Based on your description, it seems you have been experiencing a gradual decline in energy levels and possibly libido, which can be linked to inadequate caloric intake and nutritional deficiencies.
Your current dietary intake, as you described, appears to be insufficient for your energy needs. With a basal metabolic rate (BMR) of approximately 1800 calories, and considering your activity level as a part-time server and engaging in two hours of vigorous exercise, your total daily energy expenditure (TDEE) is likely much higher than what you are consuming. The combination of your physical activity and BMR suggests that you may need around 2500-3000 calories per day to maintain your weight and support your active lifestyle.

Let’s break down your meals:
1. Breakfast: A banana, a tea egg, and unsweetened soy milk provide some nutrients but are low in calories. A banana has about 100 calories, a tea egg around 70 calories, and a cup of soy milk approximately 80 calories, totaling around 250 calories.
2. Lunch: A bowl of white rice (approximately 200 calories), a chicken leg (about 250 calories), and three servings of vegetables (around 100 calories) would bring your lunch to about 550 calories.

3. Dinner: A bowl of purple rice (around 200 calories), chicken breast (approximately 200 calories), and three servings of vegetables (again about 100 calories) would total around 500 calories.

Adding these together, your daily intake is roughly 1300 calories, which is significantly below your estimated needs. This caloric deficit can lead to fatigue, weakness, and other health issues, including hormonal imbalances that may affect libido.


Addressing Your Concerns
1. Caloric Intake: It’s essential to increase your caloric intake gradually. Consider adding healthy snacks between meals, such as nuts, yogurt, or protein bars, which can help you reach your caloric goals without feeling overwhelmed by large meals.

2. Nutrient Density: Focus on nutrient-dense foods that provide more calories and nutrients in smaller volumes. Foods like avocados, nut butters, whole grains, and lean proteins can help you increase your caloric intake without excessive bulk.

3. Protein Needs: Given your activity level, ensure you are consuming enough protein to support muscle repair and growth. Aim for a variety of protein sources, including lean meats, fish, eggs, dairy, legumes, and plant-based proteins.

4. Hydration and Electrolytes: Sometimes, fatigue can also be exacerbated by dehydration or electrolyte imbalances, especially with vigorous exercise. Ensure you are drinking enough fluids and consider electrolyte-rich foods or drinks post-exercise.

5. Weight Management: If you start increasing your caloric intake to meet your metabolic needs, it’s natural to worry about weight gain. However, if you are increasing your intake with healthy, nutrient-dense foods and maintaining your activity level, you should not gain weight excessively. Weight gain occurs when there is a consistent caloric surplus, so monitor your intake and adjust as necessary.

6. Consult a Professional: It may be beneficial to consult with a registered dietitian or a healthcare provider who can help tailor a meal plan that meets your specific needs, taking into account your activity level, health status, and personal preferences.

In summary, it’s crucial to listen to your body and adjust your dietary habits to ensure you are meeting your energy needs. Gradually increasing your caloric intake with a focus on nutrient-dense foods can help improve your energy levels and overall well-being.
