CBD’s effect on homeostasis is believed to be why those in need of nutrition can experience an appetite increase and those with excess weight can experience an appetite decrease. The reason for this is that CBD is an adaptogen. Referred to by some scientists as “the boy scout molecule” because it always does the right thing in any given situation. The Journal of  Psychopharmacology tested this theory on rats in 2012. The researchers wanted to see how three common cannabinoids, including CBN, CBD, and CBG, affected the appetite of the rats. The study concluded that both CBD and CBG worked to reduce the rat’s appetite.
In the United States, the cannabidiol drug Epidiolex was approved by the Food and Drug Administration in 2018 for treatment of two epilepsy disorders.[12] The side effects of long-term use of the drug include somnolence, decreased appetite, diarrhea, fatigue, malaise, weakness, and sleeping problems.[2] As of July 2019 in the United States, CBD is a Schedule I controlled substance that is illegal for use in human foods, dietary supplements, other consumer products, or pet foods.[13][14]

But scientists have found that CBD doesn’t bind well with endocannabinoid receptors. Instead, CBD influences the system indirectly. This creates many benefits, which is why you’ll hear of CBD as a treatment for so many different medical conditions. And, unlike THC, it won’t make you high. When it comes to pain, we know that CBD has multiple functions. First, it influences neurotransmitters and receptors. One receptor known to be involved with pain and inflammation is called TRPV1 — also known as a vanilloid receptor. CBD binds to the TRPV1 receptor, influencing the way you perceive pain. CBD can also affect the production of neurotransmitters like serotonin and glutamate, which are related to pain sensation.
A 2016 study in Molecular and Cellular Biochemistry explored how CBD contributed to the fat browning process. Brown fat is a particular type of fat that works to increase energy expenditure, and it produces heat. This allows brown fat to burn more calories, but adults are mostly composed of white fat. In the study, the following was observed as a result of cannabinoid usage:
