Totally agree with the others on here, your doctor needs re-educating. Mine is the same and I avoid him as much as possible. He was another one who said the LCHF is a "gimmick" and not good for me.
More worrying was the liver specialist I see at the hospital twice a year.... Good news for me, is that she discharged me today. After nearly 2 years on LCHF my liver is back to normal and has remained that way for a year. When she asked how I did it and I attempted to tell her, she looked horrified and said.. you can't possibly eat fat, you must do low fat and try that Benecol stuff... Err excuse me ma'am , you've just discharged me for a normal liver ?? I just smiled, nodded and told her I'd do my best
