Fair point. There is research which shows your BMR may drop after sustained reduction in caloric intake, far below what your body weight would indicate. Probably one of the more well known recent ones was: http://onlinelibrary.wiley.com/doi/10.1002/oby.21538/abstract http://onlinelibrary.wiley.com/doi/10.1002/oby.21538/abstrac... - which shows the effect can go on for several years. Here's a really good article discussing caloric-reduction, impact on Leptin (key hormone involved in regulating the body metabolism): http://www.bodyrecomposition.com/muscle-gain/calorie-partitioning-part-1.html http://www.bodyrecomposition.com/muscle-gain/calorie-partiti... Though, careful reading suggests that the author believes that a day of refeeding (ala 4-hour body), is unlikely sufficient to trigger Leptin such that the body's BMR kicks back into high gear.
