It helps these organs perform healthy functions that help your body function properly, such as reducing excess fat and lowering cholesterol. Thermogens, on the other hand, work by increasing your metabolism and raising your body temperature, which requires fuel. Fuel is usually added oil. The best oil for each situation depends on your personal weight loss goals and how you want to achieve your desired results.
