My understanding is that metabolism doesn't slow appreciably
until you lower your caloric intake to 1000 below your BMR. I
certainly agree with you about the very low calorie diet not
being sustainable in the long run.
If your carbs are at 12%, that's about 200 calories a day. What
kind of carbohydrates are they---all from green veggies, or are
there grains and fruits in there too? I've found that I need to
keep my carbs to 65 calories per day (which works out to about
2.5% of total calories) in order to lose consistently and keep
insulin levels under control. If I feel my serotonin is getting
depleted, I'll have a few more carbs in the form of an apple or
pear about two hours before bedtime, but otherwise I need to
carefully monitor the source of the carbs---very little fruit, no
sugar, no grains at all---or I go into a stall, even with a nice
caloric deficit.
