Hair loss/changes in finger and toenails
A final effect which has occasionally been noted, primarily during total fasting or the
PSMF, is transient hair loss (34). In a related vein, some individuals have reported changes in
the quality of their finger and toe nails. The cause of this phenomenon is unknown but could
possible be related to protein or vitamin and mineral intake.
Summary
A number of metabolic effects have either been directly or anecdotally observed to occur in
individuals who use the ketogenic diet. As well, a number of health concerns have been voiced,
some valid, some invalid. This chapter addresses the main concerns surrounding the ketogenic
diet, as well as other effects which can occur outside of the major metabolic effects discussed in
the previous chapter.
