This is likely why CBD is capable of stimulating appetite among people that are in dire need of nutrition (such as cancer patients on chemotherapy), while at the same time suppressing appetite in those who need to lose weight. The active compound helps keep the body in balance, so if you need weight gain it can help you improve your appetite, but if you are overweight, it may be able to help curb your desire to eat.
Researchers wrote in 2011 that one of the most important functions of endocannabinoids and CB(1) receptors are to enhance the energy storage conversion into fat and reduce energy expenditure by influencing both lipid and glucose metabolism. Although normally well controlled by hormones etc., the endocannabinoid regulation of energy balance can become dysregulated and contribute to obesity, dyslipidemia and diabetes (type 2).
To briefly review, the endocannabinoid system (ECS) is a group of specialized fatty acid-based signaling chemicals (think “keys”), their receptors (think “locks”), and the metabolic enzymes that produce and break them down. These endocannabinoid chemical signals act on similar brain and immune cell receptors (CB1 and CB2) using the active compounds found in cannabis – cannabidiol (CBD), and Δ9-tetrahydrocannabinol (THC).
When the endocannabinoid system becomes dysregulated, it often becomes overactive and too much fat is being stored, particularly in the intra-abdominal tissue. Cannabidiol is known to regulate the endocannabinoid system as it can restore balance in both directions. Therefore, the study concludes that, along with lifestyle changes cannabis could be a means of fighting obesity.
