Abstract

Defined as a condition of body fat excess leading to significant morbidity, obesity is a chronic metabolic illness associated with a significant number of diseases. The incidence of obesity does not solely depend on dietary habits, with energy balance being regulated by the complex interactions between genetic, behavioural and environmental factors. Genome-wide association studies (GWASs) have demonstrated that several genes are linked to obesity, and these findings shed light on a growing number of novel potential therapeutics for weight management, including genome editing. In this regard, the cutting-edge technology known as clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR-associated protein (Cas), thanks to its ability to edit DNA or modulate gene expression in eukaryotic cells, undoubtedly enables to understand the genetic mechanisms implicated in obesity and could be a promising tool for its treatment. This chapter summarizes the genetics underlying obesity and currently available obesity treatments, further discussing the research progress of genome editing in the knowledge and treatment of body fat excess.
