A limited but at least scientific study of fasting for 8 days among middle-aged males in Poland.
After 8 days of WF, all subjects were found to remain safe and feel the sense of well-being. However, the appearance of the above-mentioned adverse metabolic effects [decreased serum Ca and Mg++ concentrations, more acidic urine], despite partially effective renal compensations, suggests that the further continuation of fasting intervention by the subjects would be detrimental to their body.
The occasional juice with celery and spinach should help with calcium and magnesium depletion. Or pop a supplement?
