How do I do this?

As a disclaimer, I am not a doctor or medical expert and in no way am I suggesting that anyone reading this should self-diagnose or start a detox program on their own without first consulting their doctor or medical practitioner.
The following is meant for information purposes only and is not meant to diagnose or recommend treatment to anyone. You should use caution when embarking upon any diet change, cleansing or detoxification program and you do so at your own risk.
With that said, the following is just my personal experience and recommendations of others who have dealt with the subject of detox and body cleansing. As a matter of fact, many thousands and perhaps millions of people before you have successfully rid themselves of harmful toxins and helped them improve their health through a proper detox.
The method of ridding the body of toxins and waste is known as a detox or detoxification. There are many different kinds of detox programs and some of them target specific organs such as the liver or the gall bladder.
A cleansing body detox is a great way to feel better and more rejuvenated. You can feel more energy, lose weight and cleanse the tissues and organs as well as give your digestive system a cleansing.
One of the most well known detoxing methods is the master cleanse otherwise known as the lemonade diet. It is basically a 10 day fasting during which you drink only fresh water with lemon juice, a small amount of pure maple syrup and a dash of cayenne pepper.
Many people have enjoyed the benefits of such a cleanse and you can too, provided you make sure you have checked with your physician or doctor to see if you have any precautions in doing so.
The health benefits are tremendous as you can rid the body of accumulated waste from the tissues and organs as well as the blood stream. We are bombarding our bodies with sugar, fats, alcohol, cigarettes, coffee and other harmful chemicals and products. Even if we do not drink alcohol or smoke, we are eating foods which might be de-natured or filled with fats and sugars and need to go on a fasting diet or a cleansing diet to get rid of some of these destructive elements.
Then there is the traditional juice fasting which has been done by many thousands of people to help cleanse and rejuvenate the body. Fresh vegetables and fruits are juiced in a juicer which separates the juice from the pulp and cellulose. A typical juice might be made from greens such as kale, spinach and parsley and a hand full of sprouts along with maybe a lemon and some ginger for punch. The lemon makes the juice even healthier and the ginger is anti viral and has healing properties as well.
But aside from maybe adding an apple or pear to a vegetable juice, keep the fruits and vegetables separate when making juices. Avoid the citrus juices and fruits.
A water fast is just fasting with only water being drunk. This allows for a real rest of the digestive system allowing for more toxins to be eliminated.
If you can, make sure to take a sauna, as a good sweat will help cleanse the skin and pores as well as get those toxins out of the body.
Some homeopathic and naturopathic physicians recommend detox kits with drops that you can take that help cleanse and eliminate toxins. Even women can notice that their cellulite starts to disappear when they clean out the toxic materials from their body systems.
