When I was diagnosed with Metabolic Syndrome that included NAFLD and horrendous readings of 183. I was referred to the hospital and had ultrasound scans and a biopsy.
Six months of strict LCHF and it had gone.. liver readings were and still are at about 35 which is considered normal.
The specialist at the hospital got bored with me and said.. "your readings have been consistently normal for 2 years now. I'm discharging you from this clinic" .. " By the way, how did you do it?.. low fat I assume ?"
She nearly fell off her chair when I replied.. " The exact opposite actually"
She screeched " You can't do that !" I just smiled instead of saying " well, doc, you just discharged me for being normal "
What I'm saying is don't expect any support from the NHS for LCHF but it definitely worked for me.
