The Body's Reactions to Fasting

Author
BY  DORIAN FACEY 

Fasting is used by many as a way to detoxify and rid the body of built-up waste. A fast can be rigorous, allowing nothing but water, or it can be less onerous, with fruit juices and herbal teas considered acceptable. Individual responses to a fast will vary and will depend on the type and length of the fast. Individuals suffering from illnesses such as cancer, AIDS and any potentially fatal disease should avoid fasting, as should pregnant women and infants. Fasting for diabetics is not advised, but should you decide to do so, you should only fast under medical supervision.

Side Effects

According to the Natural News website, your body will need three days to stop craving food, so you will be hungry during your fast. Some people suffer few side effects, while others may experience headaches and muscle pains as the body strives to accommodate the metabolic changes resulting from decreased nutritional input. Your pre-fast level of toxicity may contribute to the side effects, which could also include bad breath, blemishes and unpleasant body odor as toxins are released. Be prepared to get additional rest, since your energy stores will be low and you initially may feel fatigued.

Fasting, Cholesterol and Fats

One of the body’s responses to fasting has been reported by researchers from Harvard University. According to this study, when you fast, one of the sirtuin enzymes in your body, which they called SRT1, shuts off the proteins involved in fat and cholesterol production. Fasting causes your body to stop making and storing fat and cholesterol, and instead, starts using the fat you have already stored as a source of energy.

Fasting and Human Growth Hormone

As reported in ScienceDaily, cardiologists at the Heart Institute of the Intermountain Medical Center in Murray, Utah, conducted a research study that examined the effect of fasting on levels of human growth hormone, or HGH. HGH is involved in maintaining metabolic balance and providing protection to the body’s lean muscles. A 24-hour fast caused an average increase in HGH levels in females of 1,300 percent, while an increase of 2,000 percent was seen in males.

Extended Fast

Long periods of fasting can cause severe reactions such as decreased blood pressure, anemia, mineral imbalance and compromised liver function. While the hunger associated with a fast will eventually go away, your body still has to deal with the stress of the fast, and a long-term fast could be dangerous to your health.

What Does Fasting Do to Your System?

Author
BY  MARIE DANNIE 

Fasting is a type of metabolic therapy that uses a mix of diets, enzymes and nutritional supplements to help the body remove toxins. In fasting, you voluntarily abstain from consuming some or all foods and liquids. During a fast, your body’s digestive system undergoes several changes because it needs to rely on stored energy to provide fuel for your body’s needs. The types of changes your body experiences is determined by the length and type of fast you undertake. Before doing a fast of any kind, consult with a doctor to ensure it is safe for you to do so.

Length Of Fasts

The length of your fast will determine how many stages of fasting you go through. Even a short fast, which, according to the American Cancer Society is between one to five days, will bring you through the first stage of fasting where your body uses up stored glycogen. This is the case for water, juice and dry fasts, the latter being a fast where no food or liquid is consumed for the entirety of the fast. The second stage, which focuses on using fats as an energy source, only occurs with fasts that are three days or longer for water fasts, and four days or more for juice fasts.

The First Couple of Days

During the early stages of any fast, your body makes use of the glycogen available from your last meal, to provide energy for your body. According to Ralph Cinque, doctor of chiropractic medicine writing for the International Natural Hygiene Society, the body progresses through the gastrointestinal phase within six hours on a dry or water fast. After this, it moves onto the glycogenolysis phase. On a juice fast, because you are still ingesting nutrients, your body takes longer to move to the glycogenolysis phase, where stored glycogen in your liver is used to fuel your body. Glycogenolysis can last for two days on a water fast, and upwards of three to four days on a juice fast.

On To Ketosis

According to the International Natural Hygiene Society, once your body’s glycogen stores have been used up, the body begins breaking down stored fats to provide energy for the brain in a process called ketosis, the second stage of fasting. Ketosis most generally starts on day three of a water fast, and between days four and seven on a juice fast. During ketosis, your body also begins using fewer proteins as an energy source, and only 20 grams of protein are used each day if your fast goes into a second week, down from 75 grams per day. While fat burning is ideal for those looking to lose weight on a fast, if you are obese or overweight, you need to be careful that you do not use up your body’s non-essential protein resources, which can lead to severe weakness after a long fast, including possible damage to heart muscle.

The Detoxification Process

Fasting can be a way of encouraging your body to detoxify, getting rid of toxins that have built up due to metabolic processes, as well as exposure to chemicals, pollutants and medications. While there is little scientific evidence supporting detoxification methods, including fasting, the American Cancer Society states that many practitioners claim it helps reduce acne, allergies and headaches, as well as helping lower blood pressure and reducing the risk of heart disease. Dr. Ben Kim, a Canadian chiropractor and acupuncturist, states that fasting can help improve energy levels and sleep quality, and reduce anxiety and tension.

Weight Loss and Digestive Health

In addition to detoxification, weight loss is one of the most common reasons to go on a fast. Because of the reduced calorie intake, many people experience rapid weight loss while on a fast, losing between 2 to 3 pounds during the first few days, and then roughly half a pound a day after the initial rush. The average weight lost is 1 pound per day of fasting. Fasting also gives the digestive system time to rest, potentially leading to reduced or cured digestive disorders, and a stronger digestive system. It can also help you achieve regularity in bowel movements as your system has had a rest and is cleansed of toxins.
