A lot of experts say that majority of the metabolic diseases like diabetes, heart ailments, brain disorders, obesity, high BP and even cancers are caused because of excess. The root cause is excess of energy in the system because of which system goes into energy imbalance.
Cellular growth and multiplication happens when you have good amount of nutrients (especially macro-nutrients like carbohydrates and fats) in the bloodstream. So if our system is constantly induced with a flux of nutrients in the form of food, there is a possibility of cellular overgrowth which could result in cancer or lead to other metabolic diseases.
When nutrition is absent during fasting the cells need to survive on their own and also they need to use internal energy to survive. Now there is no possibility of cellular multiplication or over growth rather the system would use the cellular organelles and stored nutrients to survive the fasting period. During this phase the system uses up the stored nutrients but also clean up the dead cells, weak cellular molecules, other metabolic gunk for producing energy. This results in autophagy which is the core benefit of fasting.
When you are restricting the external energy, body learns to use the stored energy and also cleans up the gunk formed during metabolism. When you go on fasting you will have counter regulatory hormone surge, you will have fatty acid oxidation, you consumed stored glycogen. Cancer cells or malignant cells survive in the presence of excess nutrients especially when there is a constant flow of glucose in the blood. In the absence of glucose these cancer cell do not the thrive.
When your body is malfunctioning, this excess energy or nutrients will allow the bad cells to multiply. This also lead to storage of fat, inflammation, imbalance lipid profile, clogging of arteries, fatty liver, fatty pancreas, increase in visceral fat which is the main cause of many metabolic diseases.
