Body detox usually refers to detox diets or cleansing diets.
There are many of them. Some involve fasting, or just drinking liquids. Others allow some foods, like fruits and vegetables. They typically are short diets — not normal or recommended as a regular diet you can follow for a long time.
Some of the more popular diets are: The lemon detox diet, The Master Cleanse, The Colon Cleanse, 48-Hour Supercharged Cleanse. There are almost no studies looking at the validity of these detox diets.
Detoxification (detox) diets are popular, but there is little evidence that they eliminate toxins from your body.
Detox diets that severely limit protein or that require fasting, for example, can result in fatigue. Long-term fasting can also result in vitamin and mineral deficiencies.
Colon cleansing, which is often recommended as part of a detox plan, can cause cramping, bloating, nausea and vomiting. Dehydration also can be a concern.
So why do so many people claim to feel better after detoxification? It may be due in part to the fact that a detox diet eliminates highly processed foods that have solid fats and added sugar. Simply avoiding these high-calorie low-nutrition foods for a few days may be part of why people feel better.
Reality Check: Most Body toxins are expelled by the liver, kidneys and urinary system.
The liver, which sits in the abdomen just below the diaphragm, is the second most important organ in the body after the brain. It plays a vital role in metabolism, digestion and eliminating unwanted by-products and toxins from the body. However, it can be easily damaged by excessive consumption of alcohol.
A major function of the kidneys is to remove waste products and excess fluid from the body. These waste products and excess fluid are removed through the urine.
Intermittent fasting may help you live longer
Intermittent fasting (also called alternate day fasting) has become a popular diet. In most versions of intermittent fasting, people fast or eat very little a few days each week and then eat normal amounts during the remaining days.
Fasting can actually fix cell damage
One way that our cells can become damaged is when they encounter oxidative stress. And preventing or repairing cell damage from oxidative stress is helpful against aging. This stress happens when there is higher-than-normal production of free radicals, unstable molecules that carry a loosely bound extra electron.
When the free radical encounters another molecule, this extra electron is passed along in a rapid chain reaction from molecule to molecule. When it reaches the end of the chain, it can break apart connections between atoms within important components of the cell, like the cellular membrane, essential proteins or even DNA. Anti-oxidants work by absorbing the unstable electrons before they can do any harm.
Although fasting seems to help our cells combat damage from this process, it isn’t clear exactly how that happens.
Free radicals can be generated by poorly functioning mitochondria (the powerhouses of the cell). The switch between eating normally and fasting causes cells to temporarily experience lower-than-usual levels of glucose (blood sugar), and they are forced to begin using other sources of less readily available energy, like fatty acids. This can cause the cells to turn on survival processes to remove the unhealthy mitochondria and replace them with healthy ones over time, thus reducing the production of free radicals in the long-term.
It might also be true that fasting itself results in a small increase in free radical production early on during fasting.
The cells may respond by increasing their levels of natural anti-oxidants to fight against future free radicals. And although free radicals are commonly seen as harmful because of their ability to damage our cells, they might be important short-term signals for our body in this case, triggering cells to cope better with more severe stresses that may come in the future.by
