What is BMI?
The Body Mass Index (BMI) is one of the best-known measures for assessing body weight in relation to height. It is used worldwide in medicine and also serves as a quick guide in everyday life to determine whether someone is underweight, normal weight, or overweight. For men in particular, the BMI can be an initial indicator of health risks such as cardiovascular disease, diabetes, or hormonal imbalances.
How is BMI calculated?
The formula for BMI is:
BMI = Body weight (kg) / (Height in m)²
For example: A man weighing 85 kilograms and standing 1.80 meters tall has a BMI of 26.2 – according to the WHO, this corresponds to being slightly overweight.
BMI values and their significance
The World Health Organization (WHO) defines the following areas:
- Underweight: below 18.5
- Normal weight: 18.5 – 24.9
- Overweight (pre-obesity): 25 – 29.9
- Obesity grade I: 30 – 34.9
- Obesity grade II: 35 – 39.9
- Obesity grade III: from age 40
This classification makes the BMI a simple and internationally comparable measure of body weight.
Limits of BMI - why men should take a closer look
BMI alone doesn't tell the whole story about health. It doesn't take into account whether weight consists of muscle or fat mass. A fit, muscular man can therefore have a BMI in the "overweight" range even though his body fat percentage is low and he has no health risks.
Therefore, men should always consider BMI in combination with other measurements:
- Waist circumference (ideally under 94 cm)
- Waist-to-hip ratio
- Body fat percentage (e.g., via bioimpedance or caliper measurement)
- Visceral fat (abdominal fat in the inner abdominal cavity, particularly risky for health)
Abdominal fat is particularly critical, as it promotes inflammation, puts a strain on the metabolism and can negatively affect testosterone levels.
Health risks associated with an elevated BMI
A persistently elevated BMI of 25 or higher can promote various diseases:
- High blood pressure and cardiovascular diseases
- Type 2 diabetes
- Lipid metabolism disorders
- Joint problems and back pain
- Sleep apnea
- Testosterone deficiency and loss of libido
Especially with a BMI over 30, the risk of erectile dysfunction also increases, often triggered by narrowed blood vessels, hormonal changes and chronic inflammation.
Conclusion: BMI as a starting point, not as the sole measure
BMI is a helpful initial indicator, but it should not be the sole criterion for assessing health. Men especially benefit from considering waist circumference, body fat percentage, fitness level, and hormone levels in addition to BMI. This provides a more complete picture of their health and personal risk of developing diseases.

For whom is testosterone replacement therapy suitable?
For whom is testosterone replacement therapy suitable?

What are the benefits of testosterone replacement therapy?
What are the benefits of testosterone replacement therapy?
Testosterone replacement therapy (TRT) offers a number of potential benefits, particularly for men with clinically diagnosed testosterone deficiency. It is important to emphasize that TRT should only be used in cases of diagnosed testosterone deficiency and under medical supervision. Potential key benefits include:
1. Improved libido and sexual function: One of the most common effects of testosterone deficiency is a decrease in libido or sexual desire. TRT can help improve sexual desire and erectile function, which can lead to a more satisfying sex life.
2. Increased energy and overall well-being: Low testosterone levels can lead to fatigue, lack of energy, and a general feeling of malaise. Many men report increased energy and an improved quality of life after starting TRT.
3. Improvement of muscle mass and body composition: Testosterone plays a key role in building and maintaining muscle mass. TRT can increase muscle mass and reduce body fat percentage, especially when combined with regular exercise.
4. Positive effects on bone density: Testosterone contributes to bone health, and a deficiency can lead to a decrease in bone density. TRT can help increase bone density and reduce the risk of osteoporosis and fractures.
5. Improved mood and mental clarity: Testosterone deficiency can lead to mood swings, irritability, and difficulty concentrating. Normalizing testosterone levels can alleviate these symptoms, contributing to better mental clarity and a more stable mood.
6. Possible positive effects on the cardiovascular system: Some studies suggest that well-monitored TRT may have positive effects on the cardiovascular system, although research in this area is not yet complete.
How much does testosterone replacement therapy cost?
