Dietitian not enough? When medical support makes sense

You visit your dietitian but the weight won't budge. When is it time for medical support alongside nutritional advice? And what does it cost in 2026?

You're doing everything right. But it's not working.

You faithfully visit your dietitian. You follow the nutritional advice. You exercise more. And yet: the scales barely move.

This is frustrating. But you're not alone — and it's not your fault.

When nutritional advice alone isn't enough

For many people with a BMI above 30, lifestyle changes alone are not sufficient. That's not a lack of discipline. That's biology.

Your body has mechanisms that actively resist weight loss: your metabolism slows down, your hunger increases, and your body tries to return to its "set point."

The science is clear: for people with obesity, medical support alongside lifestyle changes is often more effective than lifestyle changes alone.

But medication is expensive and not reimbursed

That's right — in 2026, most weight management medications are not covered by your health insurance. Branded medications cost roughly €150-500 per month, depending on product and dose. For most people, that's simply unaffordable.

The alternative: compounding

What many people don't know: licensed compounding pharmacies in the Netherlands can custom-make the same active ingredients. This is called compounding and is fully legal under the Dutch Medicines Act.

Does this replace the dietitian?

No. Medical support works best in combination with nutritional advice and exercise. Your dietitian remains important. Compounding is a supplement — it helps your body work with you instead of against you.
