“Fasting and natural diet as a therapy should be the first treatment when someone discovers that she or he has a medical problem. It should not be applied only to the most advanced cases, as is present practice. Whether the patient has a cardiac condition, hypertension, autoimmune disease, fibroids, or asthma, he or she must be informed that fasting and natural, plant based diets are a viable alternative to conventional therapy, and an effective one. The time may come when not offering this substantially more effective nutritional approach will be considered malpractice”
Dr Joel Fuhrman, MD, USA.
I have practiced Regular Intelligent Fasting® for over 30 years and detailed my experiences, good and bad, in my book Eat Less, Live Long. The science and proof on fasting benefits is vast and just keeps on coming. To me, fasting is the best way to grow younger, cleanse internally and to give your body a well-deserved holiday. Fasting is allowing your body to digest and remove the stored fuel it is carrying as fat. Each pound or half kilogram of extra fat you carry is stored fuel of around 3500 calories (or two days’ food supply).
Fasting is NOT starvation
Most of us have plenty of stored fuel all over our bodies. Starvation is when your body has no fuel, no fat or nutrient reserves, and then you stop eating. I do not recommend starvation. Ironically, even though some people view fasting as dangerous or radical, it is not. Fasting is something we are genetically primed to do and we have done for hundreds of years given there has always been famine. Overeating is what our bodies do not cope with. Overeating is far more damaging to the body long-term than occasionally having a day off food.
Fasting & Eating Less protects the body
James Mitchell, associate professor of genetics and complex diseases at the Harvard T.H. Chan School of Public Health, found that when you fast (particularly for three days or more on fresh vegetable juice or water), or ‘eat less’ generally, you restrict two amino acids (methionine and cysteine), which results in the body changing production amounts of hydrogen sulfide (H2S). This protects the body during ‘lower than normal’ blood flow.
High amounts of H2S, are dangerous.
Low amounts of H2S, as created and controlled by the body when either fasting or calorie controlling, is very beneficial and is linked in many studies with longevity. The researchers said “This finding suggests that H2S is one of the key molecules responsible for the benefits of dietary restriction in mammals and lower organisms as well… it does give us a new perspective on our efforts to combat human disease and aging”.
**PLEASE NOTE: For those who are brand new to fasting and are a little unsure, please read my ‘Fasting: WARNING‘ article before you try fasting.
