Just wondering, there may be no correlation but whenever my dad goes to see my veggie (pescetarian but has fish minimally) step mum, he comes back really tired. Also she is quite overweight. I wondered if their low protein/high carb diet had anything to do with this. Dad said she has 'health issues' but did not elaborate what since they were personal. One of my fears of going veggie is not getting enough protein in my diet (I'm aware beans, nuts, lentils etc. and even dairy unless you're vegan can be used). Whenever I have mostly high-carb/low-protein I too end up tired, which makes me more anxious (since less eneergy=less focus/less control/less motivation) my libido also shoots down.
Is it possible there's any link?
