Rapid weight loss can be concerning, especially if it occurs without any intentional effort to lose weight. In your case, a drop from 60.3 kg to 59.5 kg in a single day, while it might seem minor, can still indicate underlying issues, particularly if it becomes a pattern. Here are some insights based on your situation and general medical knowledge.

Firstly, it’s essential to understand that weight can fluctuate daily due to various factors, including hydration levels, food intake, and even the time of day you weigh yourself. However, a consistent trend of weight loss over time, especially if it exceeds 1-2 kg per week without a clear reason, warrants further investigation.

In your case, you mentioned that you have a high appetite and typically consume large meals, yet you also sometimes skip meals. This irregular eating pattern can lead to fluctuations in weight. Skipping meals can cause your body to enter a state of caloric deficit, which may lead to weight loss. However, if this is accompanied by other symptoms such as fatigue, weakness, or changes in appetite, it could indicate a more significant issue.

Rapid weight loss can be attributed to several factors, including:
1. Dietary Changes: If you've recently altered your diet, even subtly, it could affect your weight. For instance, reducing carbohydrate intake can lead to quick water weight loss.

2. Increased Physical Activity: If you've recently increased your physical activity levels, this could also contribute to weight loss.

3. Stress and Mental Health: Psychological factors, such as stress or anxiety, can affect appetite and metabolism. If you're experiencing stress, it could lead to unintentional weight loss.

4. Medical Conditions: Certain medical conditions, such as hyperthyroidism, diabetes, gastrointestinal disorders, or infections, can cause rapid weight loss. If you notice other symptoms like increased thirst, frequent urination, or changes in bowel habits, it’s crucial to consult a healthcare provider.

5. Hydration Status: Weight can fluctuate based on hydration levels. Dehydration can lead to temporary weight loss, while rehydration can cause weight gain.

Given your height of 178 cm and a weight of around 60 kg, your Body Mass Index (BMI) is approximately 18.9, which is on the lower end of the normal range. While being lean can be healthy for some individuals, significant and rapid weight loss may not be ideal, especially if it leads to a BMI below 18.5, which is considered underweight.

If you are concerned about your weight loss, it would be wise to consult a family physician or a healthcare provider. They can perform a thorough evaluation, including a physical examination and possibly some laboratory tests, to rule out any underlying medical conditions. They can also provide guidance on maintaining a healthy weight through balanced nutrition and regular physical activity.

In summary, while some fluctuations in weight are normal, rapid and unexplained weight loss should not be ignored. It’s essential to monitor your overall health and seek medical advice if you have concerns. Maintaining a balanced diet, regular exercise, and managing stress are crucial components of a healthy lifestyle.
