I'm female, 19 (was 18 when I started), a uni-student and have been eating Primally since August 2012.
I lost about 5kg (of what, I don't know). Then I gained energy, meaning I could workout without it being a chore, so now I have gained 4kg of which over 3.5kg is lean body mass.
I find myself happier and more comfortable and that my body generally functions better in every sense: I sleep better, enjoy my exercise, have easier periods, enjoy my food more, snack less, eat more of what I love. I get ill less and illness doesn't take me out anymore, so I can just power through. My skin is cleaner and my body smells better, even sans soaps.
My typical daily diet at the moment is:
-100-200g of some meat or other
-3 pieces of fruit
-5 pieces of veg
+50% of my kcals from fat for optimal results, though, of course, this moves around.
