"Actively lose belly fat – the key to health!"
The goal at the health center is to shed pounds – for scientific purposes.


Despite countless diet programs, the number of people with weight problems continues to rise. 55% of German women and 65% of German men are overweight – and the trend is increasing. The latest medical research shows that being overweight, and especially visceral fat, can be particularly dangerous to health.


Visceral fat is associated with an increased risk of various chronic diseases such as type 2 diabetes, heart disease, high blood pressure, etc., the so-called metabolic syndrome. Therefore, research into effective and sustainable methods for weight and abdominal fat reduction is of great importance.

The health center, in cooperation with GfBE (Society for Movement and Nutritional Analyses) and myline (leading weight loss program in the fitness industry), aims to prove that healthy eating and strength training, in addition to overall weight loss, also reduces visceral abdominal fat and thus strengthens health.

Fifty untrained participants aged 18 and over are now being sought to take part in the study. For four weeks, nutritionist Jasmin Römer will personally guide participants through a practical weight-loss program at the health center. In addition, all participants will receive a customized training program to activate the body's largest fat-burning organ: the muscles. "Burn calories through proper muscle training instead of constantly eating less. Proper muscle training means expending a maximum amount of energy in a short time (only 2-3 hours per week) to permanently boost your metabolism. The result: Instead of eating less while losing weight, you can actually eat more!" says Römer.

Body awareness and health improve in four weeks

"Our aim is to determine precisely what participants can achieve within four weeks. Participants can lose between four and six kilos during this time. Body fat, especially visceral abdominal fat, cholesterol levels, and blood pressure can regulate themselves within this period, general well-being improves, and even minor ailments in the back, neck, joints, etc., can disappear."

The cost price for the study, including 4 weeks of training at the health center, a comprehensive InBody body analysis at the beginning and end of the study, and the accompanying study booklet with many delicious recipe suggestions for weight loss, is only €54. Our members pay €35.
