Why nutrition coaching alongside GLP-1

Three principles of my work

Muscle preservation, not just kilos

PortionIQ delivers high-quality protein, which contributes to the maintenance of muscle mass — even with a reduced appetite.

Personal guidance

I'm by your side — especially when side effects or reduced appetite make everyday life harder.

Sustainable progress

Nutrition that fits your therapy — instead of just "eating less" without a plan.

Marvin Schürhaus
About me

Hi, I'm Marvin.

I support people losing weight with GLP-1 medications like Ozempic, Wegovy or Mounjaro with their nutrition alongside the therapy — using PortionIQ, a product range developed specifically for GLP-1 users.

I'm not a doctor or a nutrition scientist with years of study — but that's exactly why I know what really matters: staying well-nourished despite a low appetite, and not facing side effects alone.

Whether you're already taking a GLP-1 medication or just considering it, I'm happy to help you get the most out of it.

01

Nutrients despite low appetite

PortionIQ delivers concentrated nutrients in small portions — exactly when appetite is lacking.

Frequently asked questions

What you might still want to know

PortionIQ is a range of portion-controlled, high-protein, low-calorie shakes, bars, soups and electrolyte drinks developed for people on GLP-1 therapy. The goal is to secure nutrient intake — especially protein, vitamins and minerals — despite a reduced appetite.

No, explicitly not. I am not a doctor or a nutrition scientist. Dosage, prescription and all medical questions about your GLP-1 medication remain with your doctor. My coaching only complements the nutrition side of everyday life.

Yes, that's exactly what PortionIQ was developed for. Still discuss side effects and your nutrition with your doctor as well, especially with pre-existing conditions.

You order the PortionIQ products yourself, online. In the initial conversation, I'll show you which products fit your situation and how to order them.

You're still welcome. Many people get advice before starting, to be well-nourished right from the beginning.

The cost mainly comes from the PortionIQ products. How much that is per month depends on your situation. We'll work this out transparently in the free initial consultation — no hidden costs.
