Intermittent fasting for digestive reset
Berg argues that it's not normal to have a bowel movement only every few days; everyone should have one to two eliminations daily. He sees the root cause of many digestive complaints as the high frequency of eating — especially snacking — which never allows the gut to finish processing one meal before another arrives. He presents intermittent fasting (two meals, no snacking) as therapeutic, giving the system relief. He also cites anecdotal evidence from prolonged fasters who still have bowel movements days into the fast, indicating the body is 'finally getting rid of stuff.' This protocol is positioned as more fundamental than any specific food recommendation.
During fasting, the migrating motor complex (the gut's housekeeping wave) activates, sweeping residual material through. Berg notes that even after days of fasting, people continue to pass stool as the body sheds old residue, demonstrating that the digestive tract requires uninterrupted time to complete elimination. By reducing feeding frequency, you also lower the constant demand on bile and enzyme secretion, reducing digestive strain.
A very healthy thing is to start to skip breakfast and not to snack. Have two meals a day. It's so therapeutic because it gives your digestive system a chance to reset and it gives it relief.
