If you can afford it (usually around $150 here in Singapore), it might be worthwhile going into a sports clinic to get a RMR reading. It's possible that your body has significantly dropped your metabolism after the weight loss, and is fighting to restore its previous weight - making further fat loss (particularly while retaining most of your lean body mass) really difficult. Ironically, in that scenario, it might be worth occasional days of increased caloric input, to attempt to trigger your body into believing that it isn't starving, and really can continue to run a high BMR. At the very least, having the data in hand is pretty cool - and it only takes about 40 minutes, inclusive of the time they need to set up the gear (just an face mask) and get you into a calm/resting state.

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/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.
