Every so often fasting – the conscious abstaining from all food or specific foods, sometimes for religious observance but sometimes for other reasons – like weight loss or “detoxing” has come back into vogue again.  There’s actually some recent research that suggests it might have some limited benefits – in rats but in a recent human study, too.   

Fasting, even if it can be useful, for how long?  How severe? Would I recommend it?  What about kids?  Read my take on this new research and my recommendations in my post in The Doctor’s Tablet.
