About this Research Topic
Metabolic flexibility has been defined as the ability of cells to oxidize substrates for energy production based on the nutrient availability and energy requirement to adjust for metabolic demand, such to sustain a dynamic balance between fuel sources, during alternation of fasting/feeding, variation of meal composition, periods of physical activity or environment modifications. Metabolic flexibility is proposed to be impaired in obesity and chronic diseases such as type 2 diabetes mellitus, cardiovascular diseases, and metabolic syndrome and is now considered as a key determinant of cardiometabolic health.
Today, the mechanisms of the dysregulation of such flexibility and the identification of involved lifestyle and metabolic factors, which ultimately will lead to metabolic inflexibility, are still investigated as they could provide relevant triggers for understanding of the development of metabolic diseases and targeted nutritional prevention and care strategies.
Moreover, the definition and the characterization (from cellular to body level) of metabolic flexibility, as well as standardized assessment methodologies are still discussed, in order to better capture its dynamic and integrative features.
This Research Topic aims to further enhance our understanding of the concept of metabolic flexibility, to refine its assessment methodologies and of its importance in the development and management of metabolic diseases and associated conditions.
We welcome Original Research articles including randomized and non-randomized clinical trials, as well as cross-sectional studies, Narrative and Systematic Reviews, Perspectives, and Opinions.
