The endocannabinoid system (ECS) plays a crucial role in regulating appetite, energy balance, and lipid metabolism, which are essential factors in obesity. In individuals with obesity, the ECS is often overactive, leading to increased appetite and fat storage. The ECS includes endocannabinoids and receptors like CB1 and CB2, which are found in the brain and throughout the body. Activation of the CB1 receptor, particularly in the brain, stimulates hunger and encourages fat accumulation. Targeting the ECS, especially the CB1 receptor, offers a potential therapeutic strategy for obesity, as reducing its activity may help in lowering appetite and supporting weight management efforts.
