NiMe

The NiMe™ (Non-industrialized Microbiome Restore) Diet is a high-fibre, whole-plant-focused eating pattern designed to reduce the risk of chronic disease by restoring gut microbiome features disrupted by the industrialization of food.

It emulates key characteristics of traditional diets in non-industrialized societies, where chronic diseases are uncommon and microbiomes exhibit a diverse range of beneficial metabolic functions.

The NiMe™ Diet is perfect if you want to:

  • Improve your health markers → lower cholesterol, balance blood sugar, reduce inflammation
  • Strengthen your gut → support a thriving, healthy microbiome
  • Demand strong science → follow a diet clinically proven diet, not another fad
  • Manage your weight naturally → protect long-term health without restrictions or gimmicks
  • Save time → enjoy ready-to-eat meals that fit into busy lives

From World-Leading Science to the Kitchen Table

Irish homes can now access a clinically validated diet with measurable benefits across key indicators of health, thanks to our groundbreaking partnership with world-leading scientists at University College Cork, the APC Microbiome Ireland (a world leading Irish Research Centre), and the University of Alberta.

Now GourmetFuel proudly and exclusively brings you the NiMe Diet.

Meet the people who created the NiMe™ Diet

Dr. Anissa Armet

Dr. Anissa Armet

PhD, RD

Anissa Armet is a registered dietitian, and currently a postdoctoral researcher at the University of Alberta.

Anissa has followed the principles of the NiMe diet for almost a decade to help manage her inflammatory bowel disease. She hopes that the NiMe diet will help others transform their health as well!

In 2017, Anissa created the recipes of the NiMe diet and contributed to the design of the controlled feeding trial as an undergraduate student.

During her PhD (2019-2024, supervised by Prof. Jens Walter), Anissa was responsible for participant recruitment and data collection, cooking the NiMe diet and data analysis.

Professor Jens Walter

Dr. rer. nat.

Jens Walter is a Professor of Ecology, Food, and the Microbiome at University College Cork and the APC Microbiome Ireland.

From 2014 to 2019, Jens served as the Professor and Campus Alberta Innovates Program Chair at the University of Alberta, where he was the lead investigator of the scientific study on the NiMe diet. He was the first to study the gut microbiome in rural Papua New Guineans, on which the NiMe diet is based.

Jens has >200 peer-reviewed publications and is a ‘Highly Cited Researcher’ according to Clarivate.

Jens will be the first to admit that he violated virtually every single principle of the NiMe diet in his younger years. After he got away with it as a young adult, the combination of a sport injury with bad diet contributed to substantial weight gain in the past.

Following the principles of the NiMe diet has helped keep the kilos off, and Jens hopes that the information on this page will help others to live healthier lives!

Why did NiMe™ choose GourmetFuel

For the NiMe™ team, scientific integrity is the most important asset.

They needed a partner who could translate the science into real-world meals without compromise. GourmetFuel stood out because of its proven track record: an evidence-based approach to nutrition and a commitment to high-quality ingredients.

“As scientists, we are genuinely impressed that a meal delivery service in Ireland operates with such strong nutritional principles. This partnership allows us to translate our science and make a clinically validated, microbiome-targeted diet accessible — without sacrificing the rigor that made NiMe™ so successful in clinical research. We are proud and grateful to work with the team at Gourmet Fuel who share our values.”

Professor Jens Walter and Dr Anissa Armet

We’re proud to collaborate with scientists whose work sets a new benchmark for health-focused eating. These are more than just meals — it’s a direct translation of top-tier science into everyday eating.

The NiMe diet is inspired by the traditional food practices of traditional, non-industrialized communities, whose long-standing knowledge of resilient and diverse food systems has informed scientific understanding of nutrition. We gratefully acknowledge this inspiration while emphasizing that the NiMe diet is a modern, science-based adaptation and not a reproduction of any traditional diet. The scientists behind NiMe are contributing in a non-profit capacity. We recognize and respect the cultural heritage of Indigenous peoples and their vital contributions to global food knowledge.
