Query: Right minded, but dated information and not detailed enough.

In my search for instructional material on how to get the most from fasting I grabbed this titled as at first glance it looked like a quick read and to the point. Upon reading it I was disappointed as it seems that it was written for a much earlier and unenlightened audience (1930's) when little may have been know about dietary practices. Most of the text is spent on promting the benefits of fasting and specificially Prof. Ehret's approach. Guidance on fasting itself is not very in-depth.Marcus Abundis
