MT Diet Always Hungry

I just took the healthexcel metabolic typing test last week and I came out as

15% sympathetic
25% balance
60% parasympathetic

30% slow oxidizer
10% mix oxidizer
58& fast oxidizer

It tells me I am I parasympathetic dominant protein type.
I've been following low carb for the past year and I have felt great until about 4 months ago. I started having bad bowel movements, gaining weight, and being tired all the time.
It seems anything I eat makes me hungrier an hour after and more tired.
It doesn't matter. I can eat pasta with meat sauce, eggs and toast, eggs and bacon, or steak and salad. It all does the same thing to me.
I'm sick of feeling like crap all day and I don't understand how I am a protein type if I get hungry right after eating meat or eggs.
I'm desperate here so any help would be really appreciated! Thanks.
