Intermittent fasting and eating rhythmicity: what we know about their impact on metabolic and gut health

2 Mar 2026

by Manon Oliero

Much of nutrition science has centred on what we put on our plate, yet when we choose to eat may be just as consequential. Intermittent fasting (IF) has gained attention as a strategy that may support metabolic health while also reshaping microbial rhythms, gut hormone secretion, and intestinal function. The growing interest surrounding this approach raises an essential question for clinical practice: does IF truly translate into measurable benefits?

Paving the way for microbiome-based therapy in clinical practice

14 Jul 2025

by Manon Oliero

After two decades of scientific exploration, the human microbiome has emerged as a critical determinant of health and disease. Fueled by multi-omics technologies and machine learning, the field has advanced from correlation-based observations to establishing causal relationships. This article presents recent and compelling examples of microbiome-based treatments that are ripe for clinical adoption and discusses challenges and opportunities facing the field based on expert interviews conducted by the GMFH team.

Fermented foods, such as yogurt, kefir, kimchi and kombucha, have gained increasing popularity on the market shelves and consumers’ basket. Scientists at Stanford University elucidate how fermented foods may alter gut microbiota profile and reduce inflammatory markers.

Should dietary guidelines advise consumers to deliberately include safe microorganisms in their diets?

While for almost all of human evolution our food and water have contained large numbers of microorganisms, the industrialized human diet contains low microbial numbers. So are we ready to recommend a specific daily intake of microbes?

The baseline gut microbiota is not always a good predictor of clinical response to a low FODMAP diet or probiotics

30 Nov 2020

by GMFH Editing Team

Diet is becoming increasingly popular as a means of managing IBS symptoms. A new study in 95 adults with IBS examines diet-gut microbiota associations and concludes that baseline gut microbiota is not a good predictor of clinical response to a low FODMAP diet or probiotic intervention.

Why does context matter in the relationships between the human gut microbiome and host lifestyle and diet?

16 Nov 2020

by GMFH Editing Team

Host lifestyle and diet are known to have a significant impact on the gut microbiome. A large observational study across 3400 individuals shows that, beyond interindividual variability, gut microbiome heterogeneity may play a role in individual responses to diet, lifestyle and medication.

The inflammatory potential of diet is tied to Crohn’s disease risk but not to ulcerative colitis, suggests a new observational study

2 Nov 2020

by Rene van den Wijngaard

Despite the fact that current guidelines for managing inflammatory bowel diseases do not devote attention to diet as a central element of treatment, there is an increasing amount of evidence that supports the role of diet in patients with IBD. A new nationwide cohort study shows the association between the level of inflammatory potential in diet and risk of Crohn’s disease.
