Some research suggests IF confers the same life-extension bene ts as caloric restriction only
when calories are consumed during daylight hours. This would, if accurate, make the Fast-5
better for fat loss than longevity.
ADCR: Alternate Day Caloric Restriction (ADCR) requires that calories be cut 5080% every
other day. It has been shown to improve insulin sensitivity, autoimmune disease, and even
asthma after just two weeks.
Protein cycling: Dr. Ron Mignery, author of the Protein-Cycling Diet, suggests that even a single
day per week of restricting protein to no more than 5% of maintenance calories can produce
effects similar to extended caloric restriction.
If the mechanism of IF or CR is a genetic self-preservation response,4 protein cycling makes
sense. There are no essential dietary carbohydrates. Simply reducing calories (or carbs) wouldn't
necessarily qualify as a biological emergency. On the other hand, even brief absences of
