The Heilbronn-Ravussin study measured BMR after 22 days of zero-intake IF and found not decrease. The question is, to what extent would a similar degree of caloric restriction lower BMR eaten every day? There is good evidence that lowering caloric intake will lower BMR by at least 10-15%. Whether this is all due to the specific dynamic action of food is unclear to me. Also, I agree with Jeff - to what extent these differences between IF and CR on metabolic rate hold over the long-term are not clear.
