You don't need to clean the inside of your body, your body does a perfectly good job of doing that all on its own. Drinking plenty of water is sufficient to rid the body of waste and toxins. Your kidneys and liver were designed to naturally detoxify your body. The kidneys and liver naturally rid the body of harmful substances and allows for “good” toxins to remain and help the body to function. The use of the Master Cleanse is harmful in that it disrupts and interferes with the liver and kidneys abilities to do their regular processes.
I know I'm probably stepping over the line here, but it's like reading that someone wants to see what it's like to be in a car crash and seeing people giving tips on how what angle to best hit the brick wall! Please listen to the posters that are recommending safe and sensible ways to make your body feel better.
I know this isn't what you want to hear, but please be cognizant of some of the risks you are putting your body through:
As part of the Master Cleanse it is suggested to drink a quart of salt water every day and to drink a laxative concoction at night. This mixture cause the fluid in your intestines to be drawn out and purged as waste. In doing this, the body is purged of electrolytes that are important and necessary to the body. Electrolytes help to regulate your body and keeps the body’s system in balance. If there is a severe imbalance of electrolytes, it could result in cardiac arrest.
Since the Master Cleanse requires only the liquid to be consumed for a good amount of time, your body will be deprived of essential nutrients and your body could rebel and you could end in a state of ketosis. Ketosis is what is referred to as chronic starvation. Due to the significant low calorie intake of the Master Cleanse, the body is thrust into a state called ketosis acidosis, which results in an excess of acid that is harmful to the body. Other negative side effects of using the Master Cleanse include diarrhea, being extremely lethargic, vomiting, severe weakness and fainting.
Because you lose lean muscle mass using the Master Cleanse because you’re not getting all of the proper nutrients that the body needs. Having a lower muscle mass means you won’t burn calories as efficiently. Since the Master Cleanse results in drastic and rapid weight loss, when you start to eat again, the weight will come back. Since being on the Master Cleanse means depriving yourself of food, your body will hold on to as many calories and nutrients it needs to in order to build that muscle mass back up.
The Master Cleanse drops your metabolism drastically. Since you’re only drinking the Master Cleanse liquid concoction, your metabolism will be lowered. Once you go back to eating normally, you’ll need to eat less calories than you normally would, until your metabolism stabilizes again. If you eat more calories right after using the Master Cleanse, the weight will come back quickly.
Again, I'm sorry for posting something you obviously don't want to hear. But just because something has been around since the 40's doesn't means it's safe, it means it's persistent. Also keep in mind that just because something temporarily makes your body feel good, also doesn't mean it's good for you. Alcohol and drugs are a great example of this.
