What exactly is body weight?
Hello doctor, I fell ill at the end of July last year, during which I couldn't eat anything and lost 15 kilograms within a month.
I'm wondering whether the weight I lost was fat or muscle.
Now I want to build a stronger body; are there any prerequisites I need to improve? I am currently 170 cm tall and weigh 58 kg.

Hello, Ling Xiang: You mentioned that after becoming ill last July, you lost your appetite and lost 15 kilograms within a month.
Based on the weight you lost, it likely included both fat and muscle.
(Muscle atrophy begins after a week of bed rest.) You stated that you want to strengthen your body; first, you need to maintain a balanced diet, drink plenty of water, and take good care of your gastrointestinal system to ensure proper nutrient absorption.
It's important to have regular and measured meals, chew your food thoroughly, and avoid cold and fried foods as much as possible, as well as processed foods.
Achieving these goals would be quite impressive.
The level of muscle definition will depend on the types of exercises you engage in.
That's about it.

More Info
When you experience significant weight loss due to illness, as you did after your illness last July, the weight you lose can come from both fat and muscle. Typically, during periods of illness, especially when appetite is suppressed and food intake is limited, the body begins to utilize its energy reserves. This process often leads to a loss of both fat and muscle mass.
In general, when a person is bedridden or inactive for an extended period, muscle atrophy can occur quite rapidly. Research indicates that muscle loss can begin within a week of inactivity, and the longer the period of inactivity, the more muscle mass is lost. In your case, losing 15 kilograms in a month suggests that a significant portion of that weight could have come from muscle, especially if you were not consuming adequate protein or engaging in any physical activity during your recovery.
Now that you are looking to regain strength and build a more toned physique, there are several key factors to consider:
1. Nutrition: A balanced diet is crucial for muscle recovery and growth. Ensure that you are consuming enough calories to support your activity level and muscle-building goals. Focus on a diet rich in whole foods, including lean proteins (like chicken, fish, legumes, and dairy), healthy fats (such as avocados, nuts, and olive oil), and plenty of fruits and vegetables. Protein is particularly important for muscle repair and growth, so aim for a protein intake of around 1.2 to 2.0 grams per kilogram of body weight, depending on your activity level.
2. Hydration: Staying well-hydrated is essential for overall health and can aid in recovery. Water plays a vital role in nutrient transport and muscle function, so ensure you are drinking enough fluids throughout the day.
3. Exercise: To build muscle and improve your overall fitness, incorporate resistance training into your routine. This can include weight lifting, bodyweight exercises, or resistance bands. Aim for at least two to three sessions per week, focusing on all major muscle groups. Additionally, include cardiovascular exercises to improve your heart health and aid in fat loss.
4. Rest and Recovery: Allowing your body adequate time to recover is just as important as the workouts themselves. Ensure you are getting enough sleep and consider incorporating rest days into your exercise routine to prevent overtraining.
5. Gradual Progression: Start slowly and gradually increase the intensity and volume of your workouts. This approach will help prevent injury and allow your body to adapt to the new demands being placed on it.
6. Monitor Your Progress: Keep track of your weight, body measurements, and how you feel overall. This will help you adjust your diet and exercise plan as needed. If possible, consider consulting with a healthcare professional or a registered dietitian who can provide personalized guidance based on your specific needs and goals.
In summary, after a significant weight loss due to illness, it is likely that both fat and muscle were lost. To regain strength and build a more toned body, focus on a balanced diet rich in protein, stay hydrated, engage in regular resistance training, and allow for adequate recovery. By following these guidelines, you can work towards achieving your fitness goals effectively and safely.
