I didn't realized that she was low carbing until I overheard her talking about her new diet that a friend had told her about and some of what she was saying didn't make sense so I approached her and asked where she heard what she was telling another mutual friend. She told me and I asked if she had done any research on any of it and she said no that it was easy and her other friend was telling her what to do. I loaned her my Protein Power book and gave her this web site and said that she should read up on it before jumping in the way she was. At that time her leg muscles were almost constantly cramping and she was having bowel problems that lasted for weeks. She took the book, but later I asked if she'd read it she said no that it was confusing and boring! She gave it back and I didn't push it.
This is a healthy way to eat if you follow the rules!
