Low cholesterol can be caused by...........
Pernicious anemia
Malnutrition
Hyperthyroidism.
All three causes can be corrected by a water-only-fast as the first two are probably caused by absorption issues of even the best of diets.
Hyperthyroidism can also be corrected in the same way, as the thyroid gland is in over-production drive and where water-only-fasting allows the body to regulate the endocrine system by self-healing/detoxing on a permanent basis.
