I think that namlesswonder has a point. Though I doubt that is a major contributing factor because you are not that low. And yes, it could take three months for a diet change to start making an impact. It could take a year to reduce your bodies accumulated PUFA. Looking at your average diet example, you are at around 25 grams or carbohydrates. That's pretty low. You know, there is no need to paint yourself into a corner when it comes to macro-nutrient distribution. There are days when I am VLC and others where I am VHC. It depends what is around. I've grown tired of the "you need to eat this much of this macro-nutrient, at this time" dogma. When you are hungry, just eat good whole food. Try to avoid the extremes - they are not likely right.
Some of you may die, but that is a risk I'm willing to take.
