Tneah-
I'm just curious. Why do you want to torture self to such a low body fat percentage? If 18% is your happy body fat percentage, why not stay there? I dare to say 13% is border line too low for good health.
When my BF% gets even close to 15% or so, I don't ovulate. Also, at lower BF percentages there is risk of bone loss and hormone imbalance.
ETA- I also disagree with the BMI reference. It does not take into account the weight of lean muscle.
