Interestingly, over-activation of the endocannabinoid system, primarily via CB1 receptor activation, contributes to increased abdominal obesity (i.e., fat gain along the midsection), glucose uptake into adipocytes (fat cells), and insulin resistance in muscle tissue. This “metabolic dysfunction” sets up a vicious cycle whereby further insulin resistance in muscles and the liver increases abdominal obesity and further CB1 over-activation, resulting in greater food-seeking behavior, increased appetite, and increased body fat gain.
But, if you are heavily obese you most probably will start with a much higher dosage. In order to find the right dosage for your situation, you can start with a relatively moderate level and, monitor for two weeks, increase, monitor etc. etc. Start with 60mg a day divided into three (or two) takings and see how much weight you lost during a two-week period.
While overstimulation of the CB1 receptor may lead to symptoms such as high blood pressure and abnormally high cholesterol levels, CBD is a CB1 antagonist, so it is not likely to cause such issues. Furthermore, the World Health Organization has recently issued a global report on CBD, claiming that it has a good safety profile and minimal adverse public health effects.
