GUIDED 90DAYS BELLY FAT CHALLENGE
Belly fat is not just a matter of appearance — it is a relevant health risk.
Excess abdominal fat is associated with increased inflammation and a higher risk for the development of chronic diseases.
Our medically supervised 90 Days Belly Fat Challenge is designed to address exactly these risks and to support sustainable health improvements.
​
What is the Guided 90 Days Belly Fat Challenge?
A 3-month, evidence-based program focused on sustainable change —
no diets, no extremes, no short-term fixes.
Goals of the Program
-
Reduction of visceral (abdominal) fat
-
Improvement of metabolic parameters
-
Building and preserving muscle mass
-
Implementation of realistic, everyday lifestyle changes
-
​
Program Structure
-
Initial consultation including explanation of the program and handover of the individual plan
-
Blood tests at baseline and after 3 months to assess progress (complete blood count including lipids, lipoprotein(a), ApoB, HbA1c, HOMA index, liver and kidney parameters, electrolytes, vitamins, iron)
-
BIA measurement to assess fat mass and muscle mass
-
performed at the beginning and end of the program (optional additional measurements in between)
GUIDED 90DAYS BELLY FAT CHALLENGE
What happens during the 90 days?
The program includes individual daily guidelines that are followed and tracked over the entire 90-day period.

4. REWARDS
A conscious reward system to support long-term adherence:
Participants may allow themselves 1–2 small rewards per week (e.g. one glass of alcohol or one sweet), provided the weekly goals are met.
Optional Add-On
For individuals with a high fat mass or significant overweight, a GLP-1-based medical therapy may be considered.
In this case, regular monitoring of muscle mass is essential to prevent muscle loss.
