As far as we care, pork scratchings, aside from needing decent teeth.
Go nuts. Lol.
Seriously, pork scratchings are high in fat and salt both of which you need on lchf. The salt is a bit high I suppose but otherwise eat your fill. A BAG. Yes a decent sized 150g bag is less than a gram of carbs. Around 300 calories which compared to a Mars bar is great too.
okra. Cigarette smoke, old, new, and permeating a room, wafting from a balcony, etc etc. That I have so many chronic diseases. That I take so very many meds. Being cold. Anything too loud, but specifically non-classical music and the television.
