Body Composition: Is My Build Healthy at 177cm and 73kg? - Nutrition

Body issues


I am currently in the second year of high school.
I would like to ask about my body measurements: I am 177 cm tall and weigh 73 kg.
I regularly play basketball, and my lower body is quite developed (my thighs have a bit of fat).
I appear muscular, but when I take off my shirt and look at myself in the mirror from the side, my stomach doesn't protrude, although the abdominal area feels soft.
I'm unsure if my body composition is considered standard.
Please help me with this question.
Thank you!

If your weight is within 75 kilograms, it is considered to be within the normal range.
It is recommended to continue maintaining an exercise routine.

More Info


To assess whether your body composition is healthy at a height of 177 cm and a weight of 73 kg, we can start by calculating your Body Mass Index (BMI). The BMI is a widely used tool that helps categorize individuals based on their weight relative to their height. The formula for calculating BMI is:
\[ \text{BMI} = \frac{\text{weight in kg}}{(\text{height in meters})^2} \]
In your case:
\[ \text{BMI} = \frac{73}{(1.77)^2} \approx 23.3 \]
According to the World Health Organization (WHO) classification, a BMI between 18.5 and 24.9 is considered normal weight. Therefore, your BMI of 23.3 falls within the normal range, suggesting that your weight is appropriate for your height.

However, BMI does not provide a complete picture of body composition. It does not differentiate between muscle and fat mass. Given that you mentioned you play basketball and have a well-developed lower body, it is likely that you have a higher muscle mass, which can contribute to a higher weight without necessarily indicating excess body fat.

You also mentioned that your abdomen feels soft and that you have some fat around your waist. This could indicate that while your overall weight is healthy, you may have a higher percentage of body fat than is ideal, particularly in the abdominal area. Excess abdominal fat is associated with various health risks, including cardiovascular disease and metabolic syndrome.

To gain a better understanding of your body composition, consider the following methods:
1. Body Fat Percentage Measurement: This can be done using calipers, bioelectrical impedance scales, or more advanced methods like DEXA scans. A healthy body fat percentage for males typically ranges from 10% to 20%, depending on age and fitness level.

2. Waist Circumference: Measuring your waist circumference can provide insight into your abdominal fat. A waist measurement of more than 94 cm (about 37 inches) in men is associated with increased health risks.

3. Physical Fitness Assessment: Engaging in regular physical activity, such as basketball, is excellent for maintaining cardiovascular health and muscle tone. However, incorporating strength training and flexibility exercises can further enhance your overall fitness and help reduce body fat.

4. Nutrition: A balanced diet rich in whole foods, including fruits, vegetables, lean proteins, and whole grains, is crucial for maintaining a healthy body composition. Pay attention to portion sizes and try to limit processed foods high in sugars and unhealthy fats.

5. Hydration: Staying well-hydrated is essential for overall health and can aid in weight management. Aim for at least 2-3 liters of water daily, adjusting based on your activity level.

In summary, based on your height and weight, you are within the normal BMI range, which is a positive indicator of your overall health. However, to ensure optimal body composition and health, consider assessing your body fat percentage, monitoring your waist circumference, and maintaining a balanced diet along with your physical activity. If you have specific concerns about your body composition or health, consulting with a healthcare professional or a registered dietitian can provide personalized guidance tailored to your needs.
