I'm sorry, this sounds like you're talking about "starvation mode". Do you have a decent source for this because everything I've seen around it is pseudoscience. You're suggesting that they, while feeling fine, have an enormous problem with one of the most fundamental processes which keeps us alive.

Your BMR drops as you lose weight, it might simply be that this hasn't been taken into account.

Or they're not tracking their calories.

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/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-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.
