Fasting – Is It Really Dangerous For Your Health?

Fasting involves restricting your dietary intake to a liquid and liquid only. The liquid can be either water, tea, or fruit juice. Proponents of fasting recommend occasional regular short fasts, lasting from two to five days, as part of a general health-maintenance regimen. Advocates recommend that longer fasts for health maintenance or the healing of illness, lasting a month or more, be conducted under medical supervision.

For fasts lasting more than one week, fruit juices are given to supply the nutrients needed to maintain health. Some add enemas as part of the detoxification fasting regimen. Proponents claim that because the body is relieved of its usual chore of breaking food down into its elemental nutrients, fasting allows the body’s inner resources to focus on cleansing and healing. Cleansing is said to be accomplished through the elimination of existing toxins.

Fasting claims to enhance the immune system and reduces the demands placed on it. In addition to its role as part of health maintenance, some believe that fasting is an effective way to treat illnesses, including arthritis, ulcers, , asthma, and other problems.

The ancient belief that fasting purifies the soul has been extended to the current view that fasting also can purify the body. Fasting maintains and restores health through physiological mechanisms. Included in these mechanisms are shifting physiological effort from food conversion to the elimination of toxins, reducing the immune system’s workload, releasing pesticides and other chemicals from body fat, and eliminating the body of nonessential tissue.

It is helpful to look at these beliefs in terms of scientific information about the well-studied sequence of events that occurs when people start fasting. When body weight declines, water and fat, but not toxins, are lost from cells. Toxins therefore are left behind. Nutrients are needed to sustain immune competence, the ability of the body’s disease-fighting immune system to make antibodies and other proteins and cells. Immune system failure, not enhancement, occurs when people do not eat enough to provide the nutrients that sustain proper immune function. Instead of reducing its workload, fasting impedes the immune system.

Advocates explain that people feel sick when fasting because toxins are leaving the body. Actually, fasting decreases the immune system’s ability to destroy and eliminate toxins. Fasting also causes a drop in blood sugar levels, which causes a breakdown of tissues needed for energy. This leads people to feel sick because the brain and other tissues fail to receive needed sugars, and the body’s metabolism is forced to remove the needed nutrients from muscle and liver tissue. At the same time, the liver and kidneys are not able to do their work of handling the by-products of protein breakdown.

Fasting can harm all organs. It is extremely dangerous to health, especially for those who are malnourished by chronic illness, yet some proponents recommend fasting to treat chronic illnesses. The slimmer the individual, the more dangerous a fast will be. The longer the fast, the more life-threatening it becomes. Studies show that when people reach 56% of their appropriate body weight, death occurs. The body cannot distinguish between intentional fasting and starvation.

Solid scientific research does not support the claims of fasting advocates. To the contrary, it contradicts those claims and indicates the dangers of fasting, even with water or juices. Reducing the number of calories you eat while maintaining a normal, balanced diet will reduce your weight. But consuming only water, tea, or juice is harmful, not helpful, to health and should be avoided especially by those who are ill.

Advocates believe that fasting can produce fatigue, anemia, irregular heartbeat, body aches, nausea, dizziness, and other negative effects. They refer to these as temporary problems that precede feelings of well-being, mental clarity, internal cleanliness, and other benefits.

Contrary to advocacy claims, fasting does not and cannot heal medical conditions, assist immune or other physiological function, or play a role in health maintenance. The decreased supply of blood glucose leads the body to break down muscle for energy, causing weakness, depression, fatigue, and sick feelings.

Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome (IBS) is a common digestive disorder characterized by abdominal pain, cramping, and changes in normal bowel function, including bloating, gas, diarrhea, and constipation.

As many as one in five adults in the has (IBS). It is a functional disorder, which means that there are no structural abnormalities seen on x-ray, endoscopy, or blood tests.

Irritable bowel syndrome is a group of symptoms you have had for at least 12 weeks in the last 12 months. It always involves abdominal pain or discomfort along with two of the following three characteristics: Pain or discomfort relieved by defecation
Change in the frequency of bowel movements
Change in the appearance of stools

Peppermint oil is widely used for . It is thought to reduce the abdominal pain and bloating of irritable bowel syndrome, possibly by blocking the movement of calcium into muscle cells in the intestines and easing excessive muscle contraction there. Peppermint is considered a carminative herb, which means that it is used to eliminate excess gas in the intestines.

Eight out of twelve studies on peppermint for irritable bowel syndrome have found that it is more effective than a placebo.

Although peppermint oil is available in many forms, it should only be used in enteric-coated capsules otherwise the oil can relax the lower esophageal sphincter and cause heartburn.

Peppermint oil, especially in excessive doses, may result in nausea, loss of appetite, heart problems, nervous system disorders, and lead to kidney failure and even death.

Peppermint oil should not be taken internally by children or pregnant or nursing women. Peppermint oil may interact with the drug cyclosporine (used to prevent organ transplant rejection and for rheumatoid arthritis and psoriasis), so they should not be combined unless under medical supervision.

Probiotics are live microbial organisms that are naturally present in the digestive tract and vagina. Sometimes referred to as “friendly” bacteria, probiotics are thought to promote health include suppressing the growth of potentially harmful bacteria, improving immune function, enhancing the protective barrier of the digestive tract, and helping to produce vitamin K.

There are over 400 species of microorganisms in the human digestive tract and the balance between beneficial bacteria and potentially harmful bacteria is important. One theory is that people with irritable bowel syndrome may have an imbalance in their normal intestinal bacteria, with an overgrowth of gas-producing bacteria.

Studies have found that probiotics may be helpful for people with irritable bowel syndrome. For example, a fairly large study published in the American Journal of Gastroenterology examined the use of three different doses of Bifidobacterium infantis or a placebo in 362 women with irritable bowel syndrome. After four weeks, the B. infantis dose of 1 x 10(8) c.f.u. was found to be more effective than a placebo at reducing abdominal pain, bloating, bowel dysfunction, incomplete evacuation, straining, and gas.

There are many different probiotic strains, and some may be more effective for irritable bowel syndrome. Another study compared lactobacillus salivarius, bifidobacterium infantis, or a placebo in 77 people with irritable bowel syndrome. Only people who took B. infantis had a greater reduction in abdominal pain, bloating, and bowel movement difficulty. For more information on probiotics, read my Probiotics Fact Sheet.

Partially hydrolyzed guar gum (PHGG) is a water soluble, non-gelling fiber that may help to reduce constipation and to a lesser extent diarrhea and abdominal pain in people with irritable bowel syndrome. PHGG also appears to increase the amount of beneficial bacteria, lactobacilli and bifidobacteria in the intestines.

One study compared PHGG (5 grams per day), wheat bran (30 grams per day), and a placebo in 199 people with irritable bowel syndrome. After 12 weeks, both the PHGG and wheat bran resulted in an improvement in absominal pain and bowel habits, but the PHGG was better tolerated and preferred.

Food intolerances may play a role in irritable bowel syndrome, possibly by triggering immune responses in the gut, leading to low-grade inflammation and an imbalance of intestinal bacteria.

The most common food intolerances reported by people with irritable bowel syndrome are dairy and grains.

A trained practitioner can supervise an elimination and challenge diet. Many foods are removed from the diet for a brief period of time, then re-introduced sequentially to isolate the body’s reaction to the offending foods. Since grains are a common culprit, it is important to remember that carbohydrate digestion begins in the mouth and that chewing grains thoroughly allows amylase, the digestive enzyme present in saliva, to digest the grains.

Pancreatic enzymes have been suggested for irritable bowel syndrome symptoms that are aggravated after a fatty meal.

Hypnosis, or hypnotherapy, has also been used for irritable bowel syndrome.

Learn About a Juice Fast

A juice fast is a type of detox diet. A juice fast involves the short-term intake of raw vegetable and fruit juice and water only. Proponents of juice fasting use juice because it’s thought to be a good source of vitamins and antioxidants.

A juice fast is considered an extreme form of detoxification because no solid food is consumed. More moderate detox methods, such as the detox diet include solid food.

Pregnant or nursing women or children shouldn’t try a juice fast. People with diabetes, low blood sugar, eating disorders, , liver disease, malnutrition, addictions, underweight, anemia, impaired immune function, infection, nutritional deficiency, low blood pressure, ulcerative colitis, cancer, terminal illness, epilepsy, or other chronic conditions shouldn’t try a juice fast or should do so only under strict medical supervision. People shouldn’t try a juice fast before or after surgical procedures. A juice fasting can reduce blood proteins and change the way prescription drugs react in the body. People taking prescription medications should consult a health professional skilled in detoxification before trying a juice fast, and should never discontinue or reduce their medications on their own.

It’s important to consult a qualified health professional before trying a juice fast.

Common temporary side effects of a juice fast include headaches, tiredness, hypoglycemia, constipation, acne, increased body odor, and bad breath.

Other side effects of a juice fast can include fainting, dizziness, low blood pressure, heart arrhythmias, weight loss, hunger, vomiting, diarrhea, and kidney problems. If these side effects occur, there is a worsening of symptoms, or new symptoms appear, the fast should be discontinued and it should prompt an immediate visit to a qualified health professional.

Another possible side effect of a juice fast is diarrhea, which can lead to dehydration and electrolyte loss.

If continued for a longer time, juice fasting can lead to nutrient deficiencies, particularly protein and calcium deficiency.

Grapefruit juice should not be used during a juice fast, especially by people taking certain prescription drugs. A compound in grapefruit can change the way certain prescription drugs are metabolized in the body. Recent evidence suggests that pomegranate juice may also have the same effect.

A juice fast typically lasts for one to three days. A longer fast requires medical supervision and possibly monitoring to ensure that nutrient deficiencies don’t result.

Proponents of juice fasting suggest fasting only during the warmer months of the year. Spring is thought to be the best time of the year for juice fasting. Seven or more days before the fast, alcohol, nicotine, caffeine, sugar, dairy, wheat, animal meat, fish, and eggs are typically reduced or eliminated from the diet. This preparation diet often consists mainly of organic fruits, vegetables, and beans. Between 32 and 64 ounces of juice is usually recommended per day during the fast. The juice is sipped throughout the day. Typical fruits and vegetables include celery, carrot, kale, cabbage, apple, pineapple, cranberry, spinach, beet, and greens. Citrus fruits are often avoided. Approximately 6 glasses of room temperature or warm filtered water is often recommended in addition to the juice. Organic fruits and vegetables are usually recommended. If organic produce isn’t available, practitioners suggest peeling the skin off fruits and vegetables or washing vegetables with a non-toxic produce cleaner, usually available at . Freshly juiced fruits and vegetables are preferred, but if unavailable, practitioners suggest buying it from the health food store or juice bar as fresh as possible. Green vegetables and sprouts contain the pigment chlorophyll, which juice proponents believe are especially beneficial during a juice fast. A combination of fruits and vegetables is recommended. Variations on the strict juice fast include eating one meal a day in addition to the juice.Certain fruits and vegetables and their parts should not be juiced, such as the pits of peaches, apricots, cherries, and other fruits, apple seeds, citrus peels, carrot and rhubarb tops, tough skins (such as kiwi, pineapple, mangoes), and bananas and avocados.

There should be a gradual return to solid foods. Read the sample guidelines on how to break a fast.
