Water fasting: Its impact on type 2 diabetes and more

When medications aren’t working I often turn to the powerful healing effect of water fasting.

This simple treatment method has now been reported to be effective for diabetics.

But dramatic improvement for type 2 diabetes is really just the tip of the iceberg for what water fasting can achieve. I believe there are several reasons to go on a liquid cleanse, from losing weight to breaking food addictions to reversing a chronic illness.

Water fasting for type 2 diabetes

One of my favorite examples is ofthree men with type 2 diabetes who utilized “intermittent fasting” under medical supervision to reverse their dependence on insulin, according to a report in the British Medical Journal of Case Reports. The case report showed that in addition to lowering their HbA1C levels (the gold standard test of diabetes control), the three patients also lost weight.

According to study author, Dr. Jason Fung, “People are focused on giving drugs to type 2 diabetics, but it’s a dietary disease,” he said.

It’s true that the concept of reversing or curing diabetes is not well-accepted in mainstream medicine today. In fact, the study author’s colleague, Dr. Abhinav Diwan, echoes that, “It [curing diabetes] is not even a therapeutic goal when people start to treat diabetics.”

Patients in the study went on 24-hour fasts. This means they ate only dinner on fasting days but could drink water, coffee and broth throughout. This was much like a water fast, but done several times a week instead of the traditional consecutive days as I explain below.

The participants were diabetic men, ages 40, 52 and 67 and all had been diagnosed with type 2 diabetes more than ten years prior. In type 2 diabetes, your body becomes less responsive to insulin, the hormone required to allow blood sugar to enter into cells for processing.

It is true that in diabetes, there is a need for caution to be safe from a hypoglycemic episode, so a water fast should be overseen by a health professional. The American Diabetes Association doesn’t recommend fasting for diabetes management.

I also know that there are other symptoms common with fasting such as headaches, fatigue, nausea, and insomnia — all of which reverse after a few days. Although we can’t make hard conclusions from this study about intermittent fasting for diabetics, we can look to the successes of previous experts of water fasting.

Water fasting’s historical evidence

Here are some bullet points to help understand more about the physiological effects of water fasting on your body, which are all accurate from my professional experience in overseeing water fasting patients and by my own personal experience:

  • After the third fast day, going without food becomes quite easy. Your hunger naturally dramatically reduces.
  • Causes detoxification, breaking down fat reserves and mobilizing stored toxins to be eliminated.
  • Allows the digestive system to rest, which begins to reverse leaky gut (hyperpermeable intestinal membrane) known to be a major underlying cause of chronic disease.
  • Begins to dramatically resolve inflammatory processes, including painful arthritic conditions.
  • Quiets down allergic reactions, such as asthma and hay fever.
  • Dries up abnormal water retention.
  • Clears the skin; sometimes skin eruptions will worsen during the fast and then the skin clears after several days of fasting (a.k.a. “Herxheimer reaction”).
  • Wakes up your taste buds and prepares you for a lifestyle of consuming whole foods.
  • Shrinks your stomach and prepares you to consume the normal amount of real food (rather than large amounts of nutrient-poor food) that will nourish you

Furthermore, water fasting has been reported to temporarily reverse anxiety, depression, and neurosis. One Japanese clinic achieved an 87 percent success rate in treating psychosomatic disease through water fasting, as reported in a 1979 issue of the journal Psychotherapy and Psychosomatics.

Water fasting and high blood pressure

In a 2001 study published in the Journal of Manipulative Physiological Therapy, researchers measured blood pressure in 174 patients who drank only water for an average of 10 ½ days, followed by a 7-day re-introduction of food using a vegan diet.

The most impressive results occurred among those with systolic blood pressure greater than 180 mg Hg (normal is below 140) and with diastolic blood pressure greater than 110 mg Hg (normal is below 90).

On average, among this group, there was an amazing reduction of blood pressure by 60 mm Hg systolic and 17 mm Hg diastolic after seven days of eating the vegan diet.  All who entered the study on blood pressure medication successfully discontinued use with no adverse effects.

The most successful liquid cleanse begins with a desire from deep within for change — some physical and/or spiritual healing.  Remember that in the process of cleansing physically, expect to experience a mental and emotional reawakening too. You can find some tips on how to do a water fast and what to expect, here.

Just remember, if you’re on medications talk to your doctor about plans to try a water fast. I would not suggest stopping any medication without the prescribing physician’s approval.
