Detoxification means cleansing the blood. This is done by removing impurities from the blood in the liver, where toxins are processed for elimination. The body also eliminates toxins through the kidneys, intestines, lungs, lymphatic system, and skin. However, when these systems are compromised, impurities aren’t properly filtered and the body is adversely affected.
Essentially, to lose body fat and ultimately weight, you have to create a calorie deficit. Exercise will help to achieve this, but obviously you have to be careful from a dietary perspective also. The times when you are not exercising are vitally important- you have to feed your body in a manner that will nourish it, without causing an increase in fat storage.
