That belly will not leave on willpower alone
You work out, you watch what you eat, and still the belly stays. That is not a discipline problem: belly fat is hormonally and metabolically stubborn, especially past 40. The good news: this is exactly the fat that responds strongest to medical treatment.

- Your blood pressure or cholesterol creeps up a little every year
- You exercise and watch what you eat, but the belly stays
- Clothes feel tighter around your waist, nowhere else
- Less energy than a few years ago
- Strict dieting works briefly, then it all comes back
Sound familiar? It's hormonal, not a lack of discipline.
Belly fat is different fat
Fat around your middle behaves differently from fat anywhere else. Three things to know:
It sits around your organs
Belly fat is largely visceral fat: it surrounds your liver and intestines and is hormonally active. That is why it is linked to high blood pressure, high cholesterol and type 2 diabetes.
Age is not on your side
From your forties onwards your testosterone gradually declines and you lose muscle more easily than fat. Your metabolism drops while your habits stay the same.
It responds well to treatment
Visceral fat is usually the first fat to go when you lose weight. Your blood pressure and cholesterol values can shift along with it, although that varies from person to person. If you already take medication for those, discuss your new values with your GP. Only your GP decides about that medication, we change nothing about it.
Losing the belly is not vanity. It is one of the fastest health wins there is.
A no-nonsense plan, medically grounded
No juices, bootcamps or strict diets. Stubborn belly fat is a medical problem, so you tackle it medically. A treatment that works on the cause, with measurable results.
Sorted quickly, assessed by a doctor
The questionnaire takes a few minutes. A registered doctor looks at your health, your medication and your blood pressure and decides whether treatment suits you. Most men can start within a few days.
Medication that puts the brakes on
GLP-1 medication reduces your appetite and the snacking in between, without food being on your mind all day.
Measurable progress
Weight, waist and dosing in one overview. You see every week what is happening and why.
At your own pace, help on hand
You work through the online modules whenever it suits you, without mandatory calls. Got a question, the team responds quickly in the chat.
Small moments,
big difference
Losing weight isn't about the scale. It's about everything that just works again afterwards.
