“Actively lose belly fat – the key to health!
The pounds should fall off in the health center - for science


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 rising. Recent medical research shows that excess weight, and especially visceral fat, can be particularly dangerous to health.


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

In collaboration with the GfBE (Society for Movement and Nutrition Analysis) and myline (the fitness industry's leading weight loss program), the health center aims to prove that healthy nutrition and strength training can not only lead to overall weight loss but also to a reduction in visceral abdominal fat, thus improving health.

The study is now seeking 50 untrained participants aged 18 and older to participate. Jasmin Römer, a nutritionist at the health center, will personally guide the participants through a weight-loss program suitable for everyday life for four weeks. 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 maximum energy in a short period of time (only 2-3 hours per week) to permanently accelerate your metabolism. The result: Instead of eating less while losing weight, you can eat more!" says Römer.

Body awareness and health improve in four weeks

"We're interested in finding out exactly what participants can achieve within four weeks. Participants can lose between four and six kilos during this time. Body fat, especially visceral belly fat, cholesterol levels, and blood pressure can be regulated within this time, general well-being improves, and even minor aches and pains in the back, neck, joints, etc., can disappear."

The cost price for the study, including four weeks of training at the health center, a comprehensive InBody body analysis at the beginning and end of the study, and the study guide with many delicious recipe suggestions for weight loss, is only €49. Our members pay €35.
