Help! My 19 year old son began Atkins about a week ago and has been pretty happy on the diet, had minimal adjustment/withdrawal problems and has lost about 7 pounds. However, suddenly, about 5 days into the diet he began having the runs from about noon till 5:00 p.m. each day. He was making cheese a large part of his intake because it was one of the things on Induction that he likes a lot. He was trying several things to deal with the runs (besides running ) and one day quit eating cheese. That seems to have brought the bowel problems under control, but now he's feeling way more restricted on the diet. Anyone who is more Atkins savvy than I (I use the Zone but put him on Atkins because it's so simple) have any insights about this problem. Is it common to have bowel problems? Will appreciate any help or advice anyone has. Thanks.
