Nutrition & Metabolism: an impressive performance since inception

Nutrition & Metabolism was co-founded by Drs. Feinman and Hussain in 2004 as an open access, peer-reviewed, online journal to keep readers up-to-date on recent developments in important areas of nutrition, exercise physiology, clinical investigations, and molecular and cellular biochemistry of metabolism. The journal is dedicated to expedite rapid publication of manuscripts that significantly advance the knowledge of nutrition and metabolism related to exercise physiology, diabetes, obesity, lipidemias, metabolic syndrome, atherosclerosis, cancer etc. Nutrition & Metabolism also publishes manuscripts pertaining to biochemistry of metabolism, cell signaling, molecular and cellular biology of nutrients, nutrient gene interactions and other areas that have implications for human nutrition and medicine. Current, but not exclusive, interests are metabolic effects of diet composition, interactions of macronutrients, effect of nutrients on gene expression, metabolic control and compartment models, nutritional effect of hormones, and genomic analysis of dietary phenomena. Since, its inception, the journal has seen a steady growth in the number of papers submitted (Figure 1). However, the number of papers published remained relatively small. This lead to a steady decline in the percentage of papers accepted for publication. Currently, Nutrition & Metabolism publishes approximately 36% of the submitted articles. The journal received an impressive first impact factor of 3.00 in 2009 indicating that published papers were highly cited soon after their publication (Figure 2). It continues to maintain its impact factor. Furthermore, several of the published papers have been highly accessed. Nutrition & Metabolism publishes two main types of articles; original research articles and brief communications, although various other forms of articles such as methods, perspectives, and letters are also considered for publication. All articles must report results of welldesigned research investigations that try to answer a
