People can also fast for medical reasons, which has been an accepted practice for many years. One reason is to prepare for surgery or other procedures that require anesthetic. Because the presence of food in a person's system can cause complications during anesthesia, medical personnel strongly suggest that their patients fast for several hours (or overnight) before the procedure.[citation needed]
Another reason for medical fasting is for certain medical tests, such as cholesterol testing (lipid panel). People are often asked to fast so that a baseline can be established. In the case of cholesterol, the failure to fast for a full 12 hours (including vitamins) will guarantee an elevated Triglyceride measurement.[citation needed]
It has been shown in many empirical, scientific studies that fasting can improve health. Although some fasting methods use juice or various amounts of food, the health of such methods is questionable, according to Dr. Joel Fuhrman. A true fast, he contends, consists of an intake solely of water, and can last (healthily) for extended periods of time when undertaken with the correct knowledge. According to Fuhrman, it is critically important to consume no calories (to put the body in Ketosis), or more than 800 calories per day, to avoid Hypoglycemia resulting in brain damage. Thus, diets of 100-800 calories/day are very dangerous. Any fasts of such nature should be preceded and followed by a healthy diet, and should also be supervised by a knowledgeable physician to make sure that deficiencies of any nutrients do not take place and detract from the healthful benefits of such a fast.[10]
Dr. Joel Fuhrman maintains that pure water fasting can not only "detoxify" cells and "rejuvenate" organs, but can actually cure[11] such diseases and conditions as cardiovascular disease, rheumatoid arthritis, asthma, high blood pressure, type 2 diabetes, colitis, psoriasis, lupus and some other autoimmune disorders when combined with a healthy diet. He believes that "Fasting is Nature's Restorer."[12] There is some inconclusive empirical evidence to corroborate the beliefs of these scientists.[12]
Recent studies on mice show that fasting every other day while eating double the normal amount of food on non-fasting days led to improved insulin and blood sugar control, neuronal resistance to injury, and health indicators superior to mice on 40% calorie restricted diets.[13][14] Alternate-day calorie restriction may prolong lifespan[15] and attenuate diseases associated with inflammation, oxidative stress and aging.[16]
People near the end of their lives sometimes consciously refuse food and/or water. The term in the medical literature is "patient refusal of nutrition and hydration".
In naturopathic medicine, fasting is seen as a way of cleansing the body of toxins and dead or diseased tissues, and giving the gastro-intestinal system a rest. Such fasts are either water-only, or consist of fruit and vegetable juices. A juice fast can also be used as a stepping-stone to a water fast, reducing the amount of discomfort experienced.[17]
Common terms used in research are: reduced diet therapy (RDT), Fasting Therapy (FT) and caloric restriction (CR). Research tends to originate from Russia, Japan and Germany.[citation needed]
