Don't have an answer for you, but I have a comment. If I calc out BMR based on my size and activity level, its a ridiculously huge number of kcals to eat, something like 3900. Supposedly cutting back by 10% would still be a ridiculous amount of food. No way it will work for me.
I read about people that increase their kcals, fat, whatever and start losing. It just doesn't work like that for me. Laws of physics still do apply. I have to burn more calories than I eat, by a longshot.
I consume about 2-2.4kcal per day and it wasn't until I really kicked up my workouts with a hardcore trainer 3x per week and added in 30min of cardio 5x that I've started to drop again. I've gone from CKD (too radical) to TKD, taking a 20-30g carbup an hour before lifting. This gets me through a heavy duty workout and I drop right back into the locarb zone right at the end of the workout.
But that's just me. I'm a hard gainer and a slow loser.
I actually think we all are somewhat unique, different things work for different people.
