MicroRNAs and Diet-induced Weight Loss: What's the Link?

It is now well established that lifestyle, particularly eating habits, modulates the synthesis and action of microRNAs (miRNAs). In particular, several nutritional schemes have proven effective in improving body composition, but molecular mechanisms still need to be fully understood. Within the complex physiological network of food intake regulation, it is essential to understand the changes in endocrine activity after the reduction of adipose tissue during a weight loss program. This could be the key to identifying the optimal endocrine profile in high responders, the assessment of musculoskeletal status, and long-term management. In this review, we summarize the state of the art regarding miRNAs as a function of weight loss and as a mechanistic regulator of the effectiveness of the nutritional program.
