My husband and I wanted to lose a bit of flab before our holiday and went on the Cabbage Soup diet. This is a high fibre, nil carbohydrate diet which is for just 7 days.
One unexpected outcome was that my husband's mobility has improved a lot. I haven't seen him swing his arm whilst walking for years. He isn't shuffling around last thing at night and in the night.
It could be that this phenomena is specific to him and his health but I wondered if others had found carbohydrates reduced mobility or perhaps affected the efficacy of drugs?
