The instafit formula
An injection alone changes little. A system does.
Sustainable weight loss is teamwork between medicine and everyday life. That is why instafit combines GLP-1 therapy with what truly carries it.

App support
Lose weight. Feel lighter. Find new energy.
That is what your program works toward – with medical supervision. How much and how fast is individual, and your doctor decides.

Alone, GLP-1 only – or better: in the programme, with support?
With your family doctor who knows and accompanies you – not a big obesity clinic where you are just a number.

* Only a physician can file a request for cost coverage. Without the programme, coordinating with the practice is up to you — and whether they have experience with such requests is an open question.
Long-term, holistic support instead of a single measure – in person, with your own doctor.

When GLP-1 therapy is not suitable
This treatment isn't for everyone. The medical assessment checks each of these points – and we advise against therapy whenever it isn't safe.
Pregnancy & breastfeeding
GLP-1 medications are not suitable during pregnancy or while breastfeeding.
Thyroid cancer history
If you have a personal or family history of medullary thyroid carcinoma (MTC) or MEN 2.
History of pancreatitis
A previous inflammation of the pancreas requires careful medical assessment.
Under 18
Treatment through instafit is for adults only.
Eating disorders
Caution applies with an active or past eating disorder such as anorexia or bulimia.
Not for cosmetic use
GLP-1 therapy is a medical treatment – not for weight loss without a medical indication.
When in doubt, the doctor decides. Your care team is available for any questions.
