Cortislim is supposed to control your cortisol levels. Cortisol is a hormone that is produced from all forms of stress in our lives. The theory is that the more stress you have in your life the more cortisol and cortisol makes you fat, fatigued, hungry all the time, causes diabetes, heart disease and a bunch more health problems. I am looking into it also and would like to know if anyone out there has tried it and what their results were.
