“You are what you eat!” — while this common saying is an exaggeration, it is undeniable that diet has a profound impact on an individual’s health. Understanding the metabolic and organismal consequences of diets is particularly important in the context of a globally rising incidence of diet-related conditions, such as obesity and type 2 diabetes.

In order to put a spotlight on research efforts that address this public health issue, the editors of Nature Metabolism are launching a joint collection on ‘Dietary interventions for cardiometabolic health’ together with Nature Communications, the newly launched npj Metabolic Health and Disease and Scientific Reports. This collection is being accompanied by a call for papers.

We welcome submissions of original primary research articles on dietary interventions, including preclinical work carried out in animal models as well as clinical studies, in both interventional and observational settings. The collection will feature topics such as caloric restriction, intermittent fasting, time-restricted feeding and other diet-related interventions aimed at improving cardiometabolic health. Additional topics of interest include dietary patterns, diet–gene interactions, the interplay between the gut microbiome and diet, and studies of the impact of parental diet on offspring. Articles will be accompanied by commissioned content from Nature Metabolism editors, such as Reviews, Perspectives or Comments.

If you are interested in submitting your manuscript for consideration in this collection, please see the collection page and the websites of the respective journals to check the relevant guidelines and requirements for submitting your work. You are welcome to reach out to the editors should you have any questions. All manuscripts will be considered for publication according to the editorial criteria of the respective journals.

By launching this collection, we signal our interest in research on this important topic and hope that, collectively, it will further advance our understanding of how diet affects organismal health and will highlight the importance of nutritional interventions to combat cardiometabolic disease.
